I do not know if you live in the Czech Republic or Slovakia, but I thought there were regulations on similar chemicals in the EU. My country produces a very large amount of ammonium nitrate so it is very cheap it costs 50 kg 50 GEL(15$). I have a bag half full, but I have not used it for a long time.

Only easy way to get pure dry ammonium nitrate where I am at is Tannerite at the ever ubiquitous sporting goods stores.

I think almost every country produces very large amounts of ammonium nitrate. Afaik even my country makes shiploads of it, as it's used everywhere universally as a fertilizer. It's also the only nitrate that is regulated by EU, as well as by stability and as purity for general public, and sale of around over 50% pure AN is prohibited. The limit was 14% by weight of nitrogen if I remember correct, as 34% would be pure. Other nitrates are not regulated, but they are on the suspicious transactions list.

I see that at least potassium and calcium nitrates are readily bought in 25kg bags for about the same price unit, although the suppliers are not walk-in-stores but more like per order, and even when they do sell by bag, they have a checklist for a full pallet of 40 bags on their site. Ironically, ordering a full ton of it would look less suspicious than just one bag. I haven't ordered one, because I definitely don't need 25kg of it, a kilo or two at max over a few years, so keeping a huge bag of the stuff lying around would be stupid.

Of course many countries produce because nitrogen and oxygen are everywhere. But in my country really a lot is synthesized. If you ask me EU regulations are great, the substance is very dangerous, for example the explosion of Beirut. This ammonium nitrate was exported from Georgia to one of the African countries in 2013, but it was stopped in Beirut, and much more was lost than it exploded. I am sure it was scored in one of the Middle Eastern countries (I will not name it). I mean it should not be sold so easily because many countries and certain groups dream about it.

Many countries likely have more advanced methods for producing ordnance, albeit AN is a cheap, bulk material. I'm in it to prevent the bad guys from getting it, but I also fear a lot that I end up on the suspected bad guys' list just because if I purchase certain reagents.

The beirut was just grave lack of safety measures, but on the same time a very classic cause for a disaster: something ends locked up because of some form of bureaucracy or a conflict of interest, and while being on hold, no one has incentive to move it because it'll likely be temporary, but it eventually becomes long-term issue, but the chain of command has already been forgotten and people just live with it. Then, some minor disaster like electric fire spreads a little and initiates a chain of events.

Oh, and my latest order/purchase? Two bottles of ethanol, ready to be stripped clean.

Is it possible to be considered a bad guy in your country after purchasing certain compounds?:D Luckily I do not have similar problems, probably because no one except me buys similar chemicals here. As for the explosion, I agree, it was just caused by negligence. (Or not, but we will never know)

I moved on a bit from the topic, therefore chemicals which i bought last were lithium hydroxide, sulfamic acid, dichloromethane and just daily acids.

Two grams of samarium. I did not think it would have such a ridiculous size, I saw such a small vial for the first time.

just did a quick and dirty nitrate test on the KNO3 I got from Walmart online. H2SO4 + product from Wallyworld + copper = NO2 fumes.

Damn good deal at $3.20/lb delivered!

Vano I've bought 1 kg of Sm metal for 130 EUR to explore its usage in organic chemistry (SmI2)

Too much :D. I'm sure you will do very good things. Iodide is an excellent reagent in organic chemistry, but I have so little, its use is nonsense.

Walmart's online shopping is like Amazon: many of their items are actually sold and shipped by 3rd party sellers, not by Walmart itself. You won't find bags of pure KNO3 in the physical store (that being said, you might be able to find stump remover which is impure but quite easy to clean up).

It arrived!! Now to do silver chemistry

Nuclear physics is neat. It's a shame it's so regulated...

Now that I think about it, that's probably a good thing. Still annoying though.

In my area you can buy KNO3 for meat curing even in hardware shop.

Analytical reagent grade basic lead acetate, having approximate composition Pb(OH)1.15(CH3COO)0.85. I could obtain 500 grams of this for only GBP 6. It dissolves in water, giving an opalescent white solution. On addition of a little acetic acid, the solution becomes colorless.

Analytical reagent grade sodium tungstate, Na2WO4. A sealed bottle of 100 grams for again GBP 6.

I also obtained a few ampoules, each containing 10 ml of BBr3. I did not yet break one of these ampoules. I still am thinking about what kind of experiments I can do with this extreme reagent. As long as the material is in the thick-walled glass ampoules, I have no storage issue with these.

Got me some TAED, sodium percarbonate and turpentine. Anyone got an idea where this is heading?

Na percarbonate + TAED you can make your white clothes even more white and shining. Distilling turpentine using powerful column and variable reflux ratio distillation head you can separate alfa pinene and other terpenes, depending on the source of turpentine (EU turpentine usually contains most of alfa pinene and less beta pinene). Maybe you can oxidize double bonds of the alfa pinene. Or if you have source of HCl gas you can make an addition of dry HCl gas to alfa pinene to produce bornyl chloride

@Fery: Exactly! My plan after fractionation of the turpentine is to
1. epoxidise the alpha-pinene: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S...
2. rearrange the alpha-pinene epoxide to campholenic aldehyde: https://patents.google.com/patent/US4052341A/
3. do some aldol-condensations with simple aldehydes and ketones, followed by reductions to yield some funky sandalwood smelling compounds. Seems like all of the big fragrance companies have their own patented analogs (under trade names such as Brahmanol, Santaliff, Sandranol, Sandalore, Ebanol etc.) and I'm interested in smelling the differences :) There's a decent overview in Surburg, H.; Panten, J. Common Fragrance and Flavor Materials: Preparation, Properties and Uses, 6th ed.; Wiley-VCH Verlag: Weinheim, Germany, 2016.

dawt thx for the link, very interesting route available to everyone!!!
also D-limonene from orange peels (or orange oil) could be epoxidized the same way producing limonene oxide:
http://www.thegoodscentscompany.com/data/rw1124781.html
also carvone (s-carvone stereoisomer could be extracted by hydrodistillation of cumin, the other stereoisomer l-carvone I prepared by 3-step synthesis from D-limonene and later I've bought here)
