The 40% regulation for H2SO4 is not a real problem. Where I live, most companies already limit sale of H2SO4 to 37% concentration (battery acid,
available in high purity colorless form). This concentration can be boiled down to well over 90% (1 liter of purchased acid then gives almost 300 ml
of concentrated acid). But yes, again a piece of nuisance for the amateur chemist.

I know about it, but I was more interested in what's legal to make yourself.
More than 40% sulfuric acid is regulated? S3 Chemicals still sells 97% food-grade sulfuric acid. Would that be illegal to order?

No it would not be illegal to order 40%.
You need to fill some form and thats it.
But keep in mind, that no matter what you do in your lab, even if it is legal, if it is discovered, they would just take everything with them and find
something they think you're guilty of.
You would probably not get anything back without a lengthy legal battle.
And that is more or less the same in every country where us home chemists live.
So actually, it does not really matter what is legal or not, keep your lips shut and you're on the safe side.

The regulation for more than 40% acid is after the start of February, 2021. So, you now still can buy 98% H2SO4 in the EU. After February 1, 2021 this
is not possible anymore. If you don't want any paperwork, then you can only buy 15% or lower, with a suitable license, you can get up to 40%. Higher
concentrations cannot be purchased anymore by any member of the general public. There will be no licensing scheme for more than 40% acid.

Ugh. That's so annoying. Would it be illegal to own it in general or just to purchase it? Since if it would still be legal to own it, I'd bulk order
sulfuric acid so that I have enough for quite a while.

After that date, there is a grace period, in which you can use up your acid (when the previous regulation for HNO3 came, there was a grace period of
18 months). After the grace period, owning conc. H2SO4 also will be illegal.
This kind of regulations indeed is a nuisance. I 'solve' the issues as follows:
1) HNO3 I make when needed. I have an all-glass NS19/NS24 distillation setup with 50 ml and 100 ml flasks. Very nice to make small quantities of HNO3
(e.g. 25 ml of azeotropic acid from a mix of H2SO4, water and KNO3). No need to store HNO3, just make it and use it when needed.
2) H2O2 still is available at 12% concentration. For most experiments that's enough. Freezing out allows making 20% H2O2 without too much trouble,
with a little more effort I could go up higher. Again, I can do that in quantities of a few tens of ml. I actually never needed this up to now.
Stockpiling on concentrated H2O2 is not possible anyway, the stuff decomposes in a few years.
3) Chlorates I make from KCl or NaCl. On my website is a detailed description on how to make small quantities (one batch is appr. 30 grams) by means
of electrolysis. Chlorates can be interesting for certain demos and as oxidizer in aqueous solution.
4) Perchlorates still can be purchased, only the sodium and potassium salts are illegal (especially the potassium salt easily can be used for making
explosives). The ammonium salt still is available, albeit somewhat expensive (but not prohibitively so). Perchloric acid also still is available, but
unfortunately that is very expensive. Commercial ammonium perchlorate is slow-burning, so not really suitable for making exposives. There also is
ultrafine particle material, but that form of NH4ClO4 is not available for the general public and also nearly impossible to make at home. I have
another application of NH4ClO4 in mind: I am still searching for a means of making nice pure HClO4 from NH4ClO4.
5) Nitromethane is something which will be beyond my reach. It be so. I know of no relatively easy method of making this from other easy to obtain
chemicals.
6) When the concentration of H2SO4 is limited, then I'll store that in concentrations, which are allowed and if I need a higher concetration for a
certain experiment, I'll have to boil down a little bit of acid. A nuisance, but can be done easily.
So, my strategy is basically to not store illegal compounds (not at all, or just in mini-quantities, just enough for one or two experiments I plan to
do within a few days). I make these chemicals from other legal chemicals, when I need them for experiments. Only nitromethane is something beyond
reach. The really determined home chemist still can do many interesting things, even with the limitations of the current regulations. Having this kind
of regulations also has a positive side-effect. It makes people more creative and forces people to build up more knowledge and experience in doing
practical chemistry.

What about buying chemical weapon precursors like thionyl chloride? I found a seller for it (in Latvia), but once again I've found no clear definition
for the guidelines of the chemical weapons act, so I don't know if it'd be legal to order it.

Draeger, at least here in the US, that might very well fall under the Patriot Act and the lesser known Domestic Security Enhancement Act, since, as
you mention, it would be a chemical weapon precursor. If you were an established laboratory (with a EIN/ tax id and such, which really isn't that
difficult to do in the States if you own a commercial address) it would be one thing, but as an individual it enables law enforcement to search for
"terrorist activity" on your person with impunity with complete disregard to the 4th amendment. Secondly, law enforcement has the right to detain you
as the federal government searches your premises to build a criminal case against you.
I would expect something similar to be true in Europe.

From having a few hundreds of ml of thionyl chloride to producing and deploying chemical weapons is a far far stretch. The chemical weopons
conventions are about tonne quantities of precursors, except maybe for a few very specific compounds, which have no other application than using them
for making chemical weapons (e.g. some specific fluoro phosphorus compounds for making nerve gases).
However, there are not many suppliers, willing to sell thionyl chloride, sulfuryl chloride, phosphorus pentachloride and more of that kind of
chemicals to the general public, not even in small quantities, but this mostly (at least in NL) is due to their extreme corrosiveness and difficulty
of storing and handling them. Only if you really know what you get in the house with these chemicals, should you try to obtain them. Storing them is a
pain in the ass, they eat caps and plastic bottles like hell. Nearby labels, tools, equipment, all is corroded by the fumes. I have some of these
chemicals, but I store them in sealed glass ampoules, the only way to keep them contained for more than a few months without issues of fumes and
corrosion. These chemicals also are dangerous to handle. They have intensely suffocating vapors and with some of them, as soon as you open the bottle,
there is a strong hissing noise of pressure release and you are greeted by a big dense cloud of HCl-fumes.
So, for a starting home chemist, steer away from this kind of chemicals (the acid chlorides, acyl chlorides) and wait with that until you have more
experience in handling corrosive compounds. Before you can run, you first need to be able to walk.

You like to invite trouble it seems.
If the only thing it is to you is a chemical weapon precursor I recommend you stay away from it.
Get isopropanol instead. It has "a few" more uses than just a chemical weapon precursor.

Nah, I was just asking right now if I ever need it in the scope of what it would be legally considered so that I don't have to ask in a few years. I
won't buy it until I have a lot more experience and proper equipment. Calm down. I just want to be able to tell what is legal and what is not, and
which restrictions some things have.

Seen the overwhelming presence of law enforcement related users here on this board, it seems appropriate to put this here.
Europe recently extended its laws on "forbidden explosive precursors". It was quite funny to see they now list >40% sulfuric illegal instead of
>10% (IIRC), oops...who knows how a lead battery works anyway huh? Anyway...
Many fireworks here still contain perchlorates as components of pyrotechnic mixtures. Huh?...Sodium and potassium perchlorates are forbidden now by
European law as explosives precursors, how is this possible?! Is this why law enforcement seems obsessed with banning all fireworks in the
Netherlands? Could I sue the pyrotechnic industry or at least the distributors? I'm a potential terrorist for having some of these fireworks in my
home.
In university I've worked with many things now listed as explosives or illegal explosive precursors. Stainings using picric acid, sodium perchlorate
for hybridization reactions, 70% perchloric acid for protein hydrolysis, and sodium azide as preservative. Funny things is I never got any warning for
how dangerous these things actually are, not a single word! .  No EOD was
present, while everone, including undergraduates, were messing around with these dangerous and highly illegal chemicals, in sometimes absurdly
dangerous ways! How does this work insurance wise? Is it that these labs have a permit as professional lab user? For 50 bucks anyone here can buy a
KVK pas and be listed as a company and order every chemical you like from what I've read. WTF?
Also, supermarkets still sell bleach, I could imagine that during warm wheather and prolonged storage, sodium chlorate would always be present. If the
bleach would be spilled, dry out and formed a crust, it would be illegal. Can I sue the supermarkets?
All high explosives are illegal...of course...Bang snaps contain silver fulminate, albeit in minute amounts, why are these not illegal? Same for
nitroglycerin, used in heart medication? Can I sue these dangergous terrorists selling these things under innocecent labels as "toy fireworks" or
"medications"?
Then there are the real criminals, real terrorists, of course...Ordering semtex from the dark web:
https://www.youtube.com/watch?v=HLYHtfryjk8
Luckily they were caught though...their sentence...uhhh...nothing. Apparently, although these guys were caught red-handed while opening a package of
semtex, it could never be proven they were the ones actually ordering it.
Thinking about the sentences some chemistry enthusiast recieved for owning illegal chemicals, it's like: Excuse me?!... say whaaaaaaat?
It seems the lessons here are:
- Potentially, lawsuits could make you a lot of money, for instating laws for which all consequences have not been completely thought thru. Have a
minor accident with bleach, or fireworks and SUE the goverment for their piss poor law enstatement!!! Really curious... if you now have an accident
with an illegal perchlorate containing firework, who is responsible?
- If you are caught as a chemistry enthusiast...deny that the stuff is yours by any means and keep denying it, works for Ali, should work for us. Keep
in mind: You mean no harm and they know it, even though they will try and find an angle to try and believe you do in order to pressurise you in
cooperating. You are dealing with people trained in psychological pressurization tactics, just keep calm and stick to the facts. 2. Be aware that in
some cases intelligence agencies may operate outside of their legal jurisdiction (they are above any law themselves), having posted potentially life
threatening information without any warning on a board where people of all ages are present. Besides, forum infiltration is highly dubious from a
human rights perspective, as acknowledged by Amnesty International. The law that foreign intelligence agencies can share information even more so as I
experienced personally. Someone should really think about the human rights violations made possible by this innocent looking little law. But he...it
is not personal, these people just need to make living. Unlike a terrorist that has recieved formal training, you as an amateur chemist are much
easier to screw over...easy meat is also meat. 3. The things you posted here might have helped to get a better overview of which chemicals to ban by
law anyway...That's right, we've all helped dig our own grave here and we have all cooperated already. It is probably one of the reasons this board
continues to exist in the first place.
-If you are a terrorist, don't spent years trying to understand the science of chemistry from OTC chemicals and post here on this law enforcement
invested board and possibly subject yourself and your family to disgusting privacy violations. lies, intimidations, seeding, manipulation, to even
material damage to your computer etc.... just order semtex and detonators via the dark web. It is mind blowing to see how the CIA can just shamelessly
invade your property, considering in several American states tresspassers may be shot without warning. Just thinking about the money needed to exert
such megalomania induced world control. Land of confusion...interesting story about Mike Masse and his son btw...he needed only a couple of
grand...

You should read the regulations more precisely. Fireworks in the Netherlands indeed contain perchlorate, but less than 40% by weight. Any mix, having
less than 40% by weight of perchlorate (or chlorate) is not illegal. The obsession of dutch law enforcement on banning fireworks is not because of
terrorism, but because of general abuse and the immense damage done to public infrastructure every year on December 31/January 1. Although I do not
like the regulations for chemicals like perchlorates, acids and so on (i.e. 98/2013 and its follow-up), I actually signed the electronic petition for
banning fireworks. I am really done with the shitload of damage with all the fireworks in the Netherlands. This has nothing to do with chemistry, it
just has to do with people being assholes, drinking too much and using too much drugs and then using fireworks to blow up things, set things on fire
and hindering people who help others (e.g. ambulance personnel, fire fighters) by throwing explosive devices to them. This is total madness and it
must be stopped, hence my signature for a ban on fireworks for the general public.
All your reasoning about bleach, which decomposes and forms chlorates and hence becomes illegal, makes no sense in this context. You at most get 15%
or so by weight of chlorate (the rest will be chloride), so no issue here as well (again, there is a 40% threshold).
The regulation also is valid only for sodium and potassium salts of chlorate and perchlorate. E.g. perchloric acid and ammonium perchlorate are not
under this regulation. Some countries may have regulations for them, but I can still buy these legally. I have read documents in which ammonium
perchlorate is discussed from a legal point of view and politics does not require any regulation of this substance from the point of view of using it
for making illegal explosives. There may be other reasons to put regulations on this (e.g. prolonged low-level perchlorate exposure affects iodine
uptake and may cause thyroid problems), but those regulations then will have wider scope, because perchlorates are used quite extensively and may be
released into the environment. Indeed, making explosives with ammonium perchlorate (without first converting it to KClO4) is quite difficult. NH4ClO4
burns and does not explode, unless it is initiated with a high explosive providing a shock wave of several km/s speed, and packed very tightly and
mixed with suitable fuel and catalyst in ultrafine (nanosize)particles.

I think you both are forgetting the most important aspect of these regulations.
They are for INDIVIDUALS.
As a company you can still get any of those chemicals in any concentration.
Or others, that have been banned for the general public for much much longer:

That sounds like a bad joke. So after Februrary 2021 you cannot buy even battery acid? What a stupid regulation. Do you know if this will apply in
every country in EU or only in some countries?

Battery acid is less than 40% so no problem there.
Not all countries seem to enforce the regulations in the same way so who knows ?
Ex: one of my suppliers stopped selling anything containing Boron and HNO3 after the "ban". They're very strict on regulations. Still sells 35% H2O2
though...

Quote Woelen: "You should read the regulations more precisely. Fireworks in the Netherlands indeed contain perchlorate, but less than 40% by weight."
So all whisteling fireworks still available (potassium (per)chlorate/ benzoate 70%/30% else it don't work IIRC) and flashpowder compositions (Thunder
kings etc) do not contain more than 40% potassium perchlorate by weight? If I am not mistaken, my question still stands, if I would have an accident
with these fireworks (or as many people already had), could they sue someone, since they legally bought fireworks that were illegal by European and
Dutch law? Maybe inform a newspaper or something to make it more public, I get more curious by the minute now... 
Quote Woelen: "The obsession of dutch law enforcement on banning fireworks is not because of terrorism, but because of general abuse and the immense
damage done to public infrastructure every year on December 31/January 1"
How much of this damage is related to illegal firework? The fireworks still legal here are not able to "blow up things", except maybe cause a
secondary fire. We also don't ban soccer because hooligans cause multi-million dollar damages every year, do we? Note that soccer is a great example,
because, like fireworks, it has no proven benefit to society, except that a lot of people seem to simply "enjoy" it. The mayor of Rotterdam said in a
press conference that new years eve had been terrible, almost like a war zone (excuse me?) with more than 50 arrests. Huh? During the queens day
celebrations in 2015, 58 arrests were made in Rotterdam. These celebrations were described as "peacefully and harmoniously".
Consider the total medical costs of smoking sigarets and the 20.000 lives it claimes anually. A total ban on fireworks would save 1-2 lives each year,
what is going on here?! https://www.nrc.nl/nieuws/2017/02/12/wat-roken-de-samenlevin...
Quote Woelen: I actually signed the electronic petition for banning fireworks. I am really done with the shitload of damage with all the fireworks in
the Netherlands.
I seem to remember you made a post somewhere about not wanting to ban the EM section, because fireworks and energetic materials are usually the first
things people naturally find an intriguing and inspiring aspect of chemistry. In fact, 50% of all people in the Netherlands seem to mostly enjoy
fireworks and for younger people fireworks are almost like magic. So despite the fact that I haven't bought much fireworks myself in recent years, I
can still RELATE to these facts.
Quote Woelen: "This has nothing to do with chemistry, it just has to do with people being assholes, drinking too much and using too much drugs and
then using fireworks to blow up things, set things on fire and hindering people who help others (e.g. ambulance personnel, fire fighters) by throwing

You mean something like this? https://m.youtube.com/watch?v=WJIyD0vt56Y
I would like to rephraze this to: This has nothing to do with FIREWORKS, it just has to do with people being assholes, drinking too much and using too
much drugs, set things on fire and hindering people who help others (e.g. ambulance personnel, fire fighters)
Note that the (completely valid) debate about aggression towards emergency services personnel is NOT specific to fireworks, but a general mentality
problem the whole year through and a frequent topic in the media. I tried to look up the actual NUMBER of emergency personel that was actually thrown
fireworks at last new years eve, and the only thing I could find was the term "dozens", which means 12 IIRC, all without any physical harm done btw.
Whenever no statistics are available, I'm inclined to presume it is an emotional argument instead. Can you imagine that if someone would be given CPR
in the street, people would deliberately throw fireworks at them? I just can't, I don't believe it, I simply don't....Emotional arguments by
social-media influenced mass-hysteria induced polarized people acheing tot put some mark on society and journalists that absolutely abuse their powers
to manipulate according to their own visions instead of profession implied objectivity, which like the oath of Hippocrates for any doctor, should be
punishable by law IMHO.
All these drunk people celebrating outside during new years eve is just the logical equivalent to trouble and property damage (like soccer,
queens/kings day and many others). A curfew seems the logical next step.

@Bedlasky: After Februrary 2021 you still can buy battery acid (IIRC this is 35-40% acid), but you need a license. Without a license the maximum
concentration is 15%.
@nitro-genes: I don't think any consumer fireworks contains more than 40% by weight potassium perchlorate. Packing materials, clay stops, that kind of
things, also have top be taken into account. If people take apart the fireworks and isolate just the composition layer which does the bang, then you
may be right, that part of the composition most likely does contain more KClO4.
My issue with the fireworks is not the exact composition, it is the abuse of it by the general public. Even with legal fireworks, a lot of nasty
things can be done. A few years ago, my wife had a burn of her hair and her coat. A medium-size fire rocket (so-called "sierpijl") was pointed nearly
horizontally by some idiot, well over 50 meters away from us. This person was shooting fire rockets in random directions, nearly horizontally, taking
no care of people who could get such a burning thing in their face. Probably this person was drunk. So, even people, wo have no relation at all with
the assholes can be severely affected.
I agree with you that there is a general mentality problem in society and also other festivals are affected by that and there indeed is a certain
hysteria around December 31, but fact remains that on December 31, the presence of all that consumer firework adds a lot of additional mayhem. I
myself also can enjoy fireworks a lot, but not at all cost. If the cost becomes so high, then (sadly) we must stop with it.
The presence of the EM-section on sciencemadness is another thing. It does not contribute to the mayhem, mentioned above. Of course, there may be some
k3wls who want an easy and cheap BANG, but mostly, the EM-section is about fascination by energetic properties of special chemicals. What sparked my
interest in chemistry most is not the fireworks, but the experiments at school in which pure chemicals were mixed and demonstrated to have fascinating
energetic properties (e.g. KClO3 + S, carefully mixed and then ignited).

Woelen: What kind of license? I doubt if government give to ordinary citizen some license for buying H2SO4 without very good reason. Or you mean
business license or something like this? But for businessman cannot be problem buy concentrated H2SO4. As I know in CZ is H2SO4 sell only in
concentrations 32-40%, 50% and 96%. So after this prohibition will be impossible buy H2SO4.
In CZ for example can be bought 30% H2O2 with identity card. You just write number of your identity card and reason for the purchase on list and
seller sell to you H2O2 without problems. If the same will be applied on buying battery acid there won't be any problem.

The license I am talking about is a license for private persons, not for businesses.
The explosives precursor law allows people to apply for a license, e.g. for hobby purposes (think of certain arts, or etching). It is up to some local
official to grant such a license or not. When applying for a license, you need to fill in a form, provide ID and have to explain why you want to have
access to the chemical. For H2SO4, the licensing is for concentrations up to 40%. Acid of higher concentration cannot be purchased at all, no license
can be obtained for that (at least not without having a business).
A similar license also is available for HNO3 (up to 10% by weight), H2O2 (up to 35% by weight) and nitromethane (up to 100% by weight). For KClO3,
NaClO3, KClO4, NaClO4, no licensing scheme is available, these chemicals may not be obtained at more than 40% concentration. You can, however, get
other chlorates and perchlorates (e.g. Ba(ClO3)2, Ni(ClO4)2 or NH4ClO4). The latter chemicals are niche chemicals and are much more expensive than the
basic sodium or potassium salts.

But isn´t it the same argumentation which the "forbidden" chemicals? A few assholes, idiots and terrorists use these chemicals for making explosives.
Even if they are a minority, they have enough impact to make the possession, use, production für members of the general public illegal.
What sucks me most....is the arrogant phrasing....e.g. [...]For some restricted explosives precursors at concentrations above the limit values
provided for in this Regulation, there exists no legitimate use by members of the general public.
[...]
Above that upper limit value the risk of the illicit manufacture of explosives outweighs the negligible legitimate use of those explosives precursors
by members of the general public, given that alternatives to, or lower concentrations of, those precursors can achieve the same effect. [...]
where my crest is rising (in German: Mir schwillt der Kamm...): Okay there is a "balancing of legally protected interests" (Güterabwägung), but if I
look at the phrase " the negligible legitimate use" then I want to take the authors of it and the "experts" and shove it up to a place where no light
shines (an eine Stelle stecken wo kein Licht hinkommt) without lube.
Sorry I make for photography and other uses silver nitrate and for that I need conc. nitric acid, there are neither alternatives nor it works with low
concentrations, that means for me and for that LEGAL purposes is the use of concentrated nitric acid definitively not negligible and that is the
reason why I perceive this as arrogant and beneath contempt (unter aller Sau) and it shows IMHO how bureaucrats are wired differently and there
opinion from the "general public" aka "responsible citizen".

Chemicals/fireworks
I'm sorry to hear of the bullshit you have to put up with in
Europe because of assholes and nanny-state mentalities.
As a rule, most chemicals can be possessed in the U.S.
with exceptions such as some precursors to chemical
warfare agents. Many precursors related to drug making
aren't banned but could get a person a knock on the
door by the DEA.
There are federal restrictions on the types and amounts of
chemicals allowed in consumer fireworks.
Prohibited chemicals in consumer fireworks:
(a) Arsenic sulfide, arsenates, or arsenites.
(b) Boron.
(c) Chlorates, except:
(1) In colored smoke mixtures in which an equal or greater amount of sodium bicarbonate is included.
(2) In caps and party poppers.
(3) In those small items (such as ground spinners) wherein the total powder content does not exceed 4 grams of which not greater than 15 percent (or
600 milligrams) is potassium, sodium, or barium chlorate.
(d) Gallates or gallic acid.
(e) Magnesium (magnesium/aluminum alloys, called magnalium, are permitted).
(f) Mercury salts.
(g) Phosphorus (red or white). Except that red phosphorus is permissible in caps and party poppers.
(h) Picrates or picric acid.
(i) Thiocyanates.
(j) Titanium, except in particle size greater than 100-mesh.
(k) Zirconium.
Consumer fireworks. Any small firework device designed to produce visible effects by combustion and which must comply with the construction, chemical
composition, and labeling regulations of the U.S. Consumer Product Safety Commission, as set forth in title 16, Code of Federal Regulations, parts
1500 and 1507. Some small devices designed to produce audible effects are included, such as whistling devices, ground devices containing 50 mg or less
of explosive materials, and aerial devices containing 130 mg or less of explosive materials. Consumer fireworks are classified as fireworks UN0336,
and UN0337 by the U.S. Department of Transportation at 49 CFR 172.101. This term does not include fused setpieces containing components which together
exceed 50 mg of salute powder.
From opening of NCIS New Orleans - It goes a BOOM ! BOOM ! BOOM ! MUHAHAHAHAHAHAHA !
