Sulphuric Acid in Australia

Phthalic Acid - 11-8-2011 at 02:15

Hi everyone, thought I better introduce myself since this is my first post (I've been lurking for a while though). I'm 19 years old and work at a sheet metal workshop (stanless steel, aluminium and whatever else). Chemistry was the only subject at school I was actually passionate about, and funnily enough the only one whose marks reflected that. I took a chem paper at uni as an elective (I was actually doing Management Studies) but decided uni wasn't for me. I just moved over to Australia from NZ and decided I'd like to do a bit of home chemistry as a hobby =) This brings me to the reason for this post...

I just went on a two hour mission to look for a few things I need to complete my lab. For the life of me I couldn't find anything at Bunnings (Australia's Home Depot I guess) that even had a small amount of H2SO4! Not only that but the only DCM and Toluene I could find was 60% max and with who knows what added to it... So I decided to cut my losses and buy some battery acid and boil it down (which I was hoping to avoid.) The guy at SuperCheap Auto kindly informed me that H2SO4 is illegal to sell to individuals in Australia unless they buy a battery with it (and even then it's only a 1L bottle!)

So finally getting to the point of this post, how do you other Aussies get your H2SO4 and what other chemicals are banned/restricted/illegal or otherwise hard to source? It seems like things are pretty strict over here...

Tell them you're into wind-generation using a stack of lead-acid batteries for storage after familiarising yourself with some technical terms of the process . . .

Phthalic Acid - 11-8-2011 at 03:31

I'd still have to buy the batteries though haha so it wouldn't be very efficient! Unless I register as a business I can't buy it without buying batteries too, no matter what story I come up with...

So then I guess you already know the solution. You need to buy some batteries.

hissingnoise - 11-8-2011 at 05:09

Yes, telling lies convincingly is a 'learned' art . . .

hissingnoise - 11-8-2011 at 05:19

But seriously, I can buy cheap, clear drain-cleaner @ 85% - the dark stuff is 93% but the contaminants put me off!
Boiling off 12% water is easy . . .
Isn't it available in Oz?

I'm not willing to buy several car batteries for a few liters of 30% H2SO4... Come on now if you aren't going to give me anything constructive then don't post at all.

Anyway, no hissingnoise it isn't available here. At all. I guess I'll have to make it then... I think I'll try my hand at the electrolysis of Copper Sulphate. I am not very experienced with electrochem (apart from a few experiments at high school) but I understand the theory quite well. Can anyone point me in the direction of any material regarding current/voltage required for this process? I imagine the voltage needed would have to be equal to or greater than the difference between the redox potentials of: 2H2O -> 4H+ + O2 (anode) and Cu2+ -> Cu (cathode) which is -0.89v. So putting in a voltage above 0.89v should do the trick right? Is there any advantage to putting more voltage in? Does the current just affect the rate of reduction/oxidation?

If anyone can shed some light on this it would be greatly appreciated!

plante1999 - 11-8-2011 at 06:36

Use 2-4 carbon rod from lantern battery satured sol. of CuSO4 4 Volt Dc 2amp.

Two patern for the electrode is usefull , first ( the less efficient patern) 1 anode at 1 inch from 1 cathode , the more efficient principle is 3 anode in a equidistan triangle shape and in the center , a cathode.

Current also affect the corosion rate of the anode.

Personaly when I start making chemistry , my first source of HSO4- was sodium bisulfate for pool ph down and after 2-3 week or so i make it from NaNO3 + S , search for ''lead chamber process''.

hope it will help you.

bquirky - 11-8-2011 at 06:44

I wouldn't take legal advice from 'the guy' at supercheap auto.

you can buy it in 2l flasks from sigma chemicals they have a outlet in balcatta wa that ive purchaced over the counter from
but there a national company

just walk in and say 'hi id like some h2s04' it cost me about $30 last time i picked some up.

if your not comfortable not having a 'proper' reason tell them that you recondition batterys and want the concentrate so you can 'fine tune' the concentration of the cells

Phthalic Acid - 11-8-2011 at 06:57

Thanks for the info plante1999! You seem to have a lot of experience with H2SO4, which method did you find was the highest yielding/easiest/cheapest? The lead chamber process is really interesting, I'm reading over the "H2SO4 by the Lead Chamber Process - success" thread right now. Just for the experience I might try both =)

bquirky, that's a good point. Do you think the laws may be different between states (I'm in QLD btw) or is chemical control a federal thing? Thanks for the advice on the cover story haha but I've never had a problem with things like that =) Is there anything else you can think of that I should know about over here regarding chemicals etc.?

plante1999 - 11-8-2011 at 07:14

Do you have charcoal and a place to make 1.5 feet pile of it , or you have only a 50 ml beaker for making it?

Wath I want to said is there is many way for H2SO4 but some need extreme temp , apparatus.... If you can specify your requirement to me it will be more simple expl: cheap.

Substitute to H2SO4

NaHSO4 , Sodium hydrogen sulfate , Pool Ph down

Process to make H2SO4:

heat to 700 degree C NaHSO4 and spray water vappor in the gas that will form , H2SO4 will condance note , it will heat strongly.
electrolisis of CuSO4
Burning sulfur and passing the gas in 3% H2O2
burning sulfur With NaNO3
Metabisulfate + bisulfate and the SO2 produce pass in H2O2
dry distill FeSO4
Persulfate hydrolisis and passing SO2 in the sol of hydrolised Persulfate.

And manny other process that I have tested but my two favorite are
NaHSO4 as an substitute and NaNO3 + S

metabisulfite + hcl creates SO2 and you pass that thru h2o2 and get H2SO4 the

Mixell - 11-8-2011 at 10:52

What about burning sulfur to get the SO2?
You can even try and make it via the SO3 route (vanadium pentoxide is available on ebay), although its quite complicated and the yield can be quite poor.

What are the details on this? Are you saying you can distill sulfuric acid from iron(II) sulfate? If you've got a reference I'd love to read about it, as I have quite a bit of FeSO4 "waste".

plante1999 - 11-8-2011 at 12:06

Simply make a google search :

FeSO4 dry distill H2SO4

It was the first process for sulfuric acid production.
I tested it and it worked good , but you need to heat with a 700 degree Celcius torch.

hissingnoise - 11-8-2011 at 12:11

On heating hydrated ferrous sulphate (green vitriol), impure sulphuric acid will come over, but heating the ferric compound will produce a mix of SO2 and SO3 which can be led into conc. H2SO4 to produce oleum.
Using water to absorb SO3 will produce a troublesome acid mist . . .

Neil - 11-8-2011 at 15:57

I'd check around a bit more if I were you.

The web says sulphuric is banned in Au as a food additive but I could find no encompassing ban.

Cleaning Sulphuric acid sometimes gets banned when people pass "sulphate bans". That happened to the area where I live, all it meant was that the retail places didn't carry it. If I wanted it I had to drive over to a different county or look in the business parks.

Mind you most of the hardware stores started carrying a sketchy Quebec drain opener which is sulphuric and has no MSDS... but I digress...

Try calling up a cleaning supply wholesaler. Instead of buying car batteries have a big pile of rusty steel that you need to pickle...

Also the company that made MOFLO still lists it as a product on their website http://www.momar.com.au/content_common/pg-plumbing-drain-unb... if you ask em they may give you a list of distributors.

cyanureeves - 11-8-2011 at 16:18

go to a junk yard and tell them to sell you used battery acid. it aint like the employees there are the highest paid in the country so they'll maybe want to make a buck. i bet you all they want is the core and i figured that if lead goes through passivation then the lead that has reacted with sulfuric acid will be in the sediment and on the plates leaving relatively clean sulfuric acid in the carcass.

starman - 11-8-2011 at 22:46

Pthalic acid.You want "fume free",or" low fume" acid from a swimming pool supplier,Its 30% H2SO4 and reasonably clear.You may have to check around a bit,but you are certain to find 5 and 20 litre containers.

Panache - 11-8-2011 at 22:55

they sell mo flo 98% h2so4 draincleaner at reece, tradelink and selected hardware stores, expensive though, $40.00/l. I think at reece they want you to be an account holder, i'd say you'd know a plumber or two (being a sheety) so voila!

boonga - 11-8-2011 at 23:58

Hey Phthalic,

I'm from Melb and have also run into this problem. I obtained a few litres of battery acid from local automotive stores. Here too, they do not sell directly to the public as it is prohibited. However, I simply told the clerk that I purchased a "dry" battery from interstate (ie; the battery was delivered to my home without the electrolyte (H2S04/H20 mixture). This isn't abnormal, many people who purchase motor bike parts and the likes run into this problem. I was able to purchase a 1L bottle for $12. Visiting 3-4 stores solved my problem. Concentrating it after was easy, i used the method from this website: http://amazingrust.com/experiments/how_to/Concentrating_H2SO... You probably already know how to do it, but i find extra info is always helpful one way or another

. After boiling, i ended up with just under 1L (about 850ml) of concentrated acid. The density of the final liquid was around 1.83 (using a battery hydrometer) which is equivalent to a concentration of 95% give or take...good enough for any home experiments surely.

Hope this helps,

Good luck

Boonga

Bismuth - 12-8-2011 at 01:40

If you're committed, I know you can find 20kg of 98.5% for the price of $25 in central Melbourne. Sold to even regular average day joes provided you can come up with a reason for needing it (not exactly hard). Industrial suppliers are more than happy to help people out still. It's a rather useful reagent, and really it's not one that comes to mind in their eyes as to being overtly suspicious. The only terms of agreement was that it has to be transported separate to the nitric acid, ie. individual trips.

People just need to do some more looking in my opinion.

Phthalic Acid - 12-8-2011 at 03:49

Thanks a lot for all the replies and suggestions guys!

Now a few of you have said that I need to look a bit harder and stuff like that. In my defence, the point of this thread was to save me time in tracking it down by using information that others in my situation provide (and gain some knowledge of the local/national laws).

Anyway, thanks a lot this pretty much solves my problem

I'm in QLD by the way, Gold Coast to be exact. Anyone else from around here?

EDIT: Thanks Panache, there's a Tradelink just down the road from where I work! I'll give that a shot tomorrow (although that does sound a tad pricey...)

[Edited on 12-8-2011 by Phthalic Acid]

Neil - 12-8-2011 at 04:59

Does anyone know why it is illegal to sell it to the public? Is it anti terror/drug/bomb making or just nanny-ism?

A good rule of thumb that has served me well in locating reagents is to type in synonyms for the reagent along with "msds" and local retail names into google.

for example if I type in "sodium bromide, msds, Canadian tire"
I find the msds for what ever product Canadian tire sells that contains what I want.

I found KNO3, NaBr, 30%H2O2 and KOH that way. It's easier then reading every isle in the cleaning section with old women glaring at you...

Mixell - 12-8-2011 at 05:23

If you have the ability to reach high temperatures (700C or more) you can decompose CuSO4 or any other sulfate that form an oxide of the metal and SO3, lead the SO3 vapors into water and you can get a very concentrated sulfuric acid, or even oleum! Although its very risky and better just buy the acid from somewhere if you manage to...

hissingnoise - 12-8-2011 at 06:09

I've stated several times on various threads, that SO3 produces a practically incondensable acid mist when led to water and, BTW, at 700°C the decomposition rate of SO3 is ~87% . . .
Cracking Na2S2O7 proceeds at ~466°C and the issuing gasses are readily absorbed by conc. H2SO4 to form oleum!

Phthalic Acid - 12-8-2011 at 18:58

That's a good idea Neil, I'll be sure to try that next time (probably for H2O2). Just went to Tradelink and asked if they sold Moflo drain cleaner. The guy said yeah and I asked for a liter of it. No problems whatsoever, he just said "be careful with it". It was $45 but a liter will last me a while and making it myself would've been vastly more expensive I imagine. Success!

MeSynth - 13-8-2011 at 00:41

Sulfuric acid can be produced in the laboratory by burning sulfur in air and dissolving the gas produced in a hydrogen peroxide solution.

SO2 + H2O2 → H2SO4

this was found on wikipedia...

did you not look through the sullfuric acid wiki before boiling down batery acid?

anyways...

There are some good videos on youtube that demonstrate how to synthesize sulfuric acid using different methods.

The drain cleaner you get from the store will be impure and may contain organic matter that discolors the acid. To purify it boil off the water and then turn up the heat to around 400c for a while. If it is a dark pos drain cleaner it will give off a lot of smoke which is coming from the impurities decomposing. after heating for a while longer the color should clear up and you should be able to see through it eventually. it will most likely be discolored a very nice clear yellow. when no more visual changes are observed you can turn off the heat and store it in the same bottle it came in. (after you wash and dry it. duh)

[Edited on 13-8-2011 by MeSynth]

Phthalic Acid - 13-8-2011 at 00:56

First of all, H2O2 in higher than 3% concentrations is just as hard to find as H2SO4 (well in my case anyway) which makes that method not very viable. Second, I didn't boil down battery acid, I bought concentrated stuff over the counter (and boiling down battery acid would've been easier than dealing with burning sulphur and directing gases anyway.)

And I am well aware of the various methods of synthesizing it myself, hence why I was asking about electrolysis of Copper Sulphate. There were a few methods mentioned here that I wasn't aware of though (lead chamber process for example) which sound very interesting. I'd like to have a go at a few just for the practical experience.

And what gives you the impression I need lots of acid? I didn't say anywhere that I needed a certain amount and I got 1L because that'd the smallest bottle they had.

theflickkk - 13-8-2011 at 06:32

Personally, I've found it near impossible to obtain sulfuric acid OTC. Firstly, laws regarding the purchase of chemicals is very strict here. Secondly, battery acid can only be obtained together with lead-acid batteries. A lead-acid battery containing approximately 500ml of acid costs roughly 30USD so its really too expensive.
What I've done was to synthesize a small amount of sulfuric acid via a really really long method.
Copper sulfate was prepared from ammonium sulfate hydroponics fertilizer and household ammonia.
A copper sulfate solution was then electrolyzed, filtered and concentrated by boiling down.
Despite being so troublesome, this long winded method is definitely the best I can do for now to get a few mls of conc. H2SO4.

uchiacon - 13-8-2011 at 19:06

Oh come on guys, you can't find technical grade sulfuric acid in australia? Freakin australia? Really? I buy 99% sulfuric acid in christchurch, new zealand, in 25L containers, without an account, without ID and without any questions from a huge chemical wholesaler for $3/L. Furthermore, I'm sixteen.

All these people giving suggestions about making it and buying drain opener... fucking seriously...

You do not stop searching until you have found it. It's really simple. There are some chemicals I need to import from china because I cannot find them here, but in the end I always find what I need.

theflickkk - 13-8-2011 at 23:07

I really wish I could indeed just buy sulfuric acid. Too bad its one of the many chemicals that are banned where I'm from.
Singapore is such a small country so there aren't many chemical wholesalers or people interested in home chemistry. Besides, even chewing gum is banned LOL It may be easy to obtain chemicals where you're from but that doesn't mean that it applies universally.

Where i live(EU), gas station's are obligted to take old car batteries and recycle them, but usually they store those batteries just outside on the back of the station, when i was younger and i was sure no place would sell me sulfuric acid, me and the boys went to those stations and had a funnel and 5l bottle to salvage the treasures of those batteries.As far as i know the gas stations only check security tapes when they are robbed.Where in australia do old car batteries go? do you have to take them to somewhere to be recycled?

But i suspect that sulfuric acid will be harder to come around here as well, because i believe all batteries i'v seen in here are 'non maintentace' ones. Besides car batteries dont cost much to replace so i dont think anyone is really wasting their acid for that

Does anybody thought about Ozone method. Its powerfull oxidizer, so it will probably oxidize SO2 to form SO3. I think the reaction will proceed something like this:

SO2 + O3 = SO3 + O2

If H2O2 works than this should work too..

Unless you want to lose your chemicals, your glassware and a whole lot of money, time and effort, I'd strongly suggest that you be VERY FUCKING CAREFUL in the Sunshine State (or the wicked witch of the East's Flying Monkey Squad will visit - been there, done that).

I've also had some serious problems purchasing H2SO4 in Queensland, there is a cleaning chemical company (named after a brand of soup - go figure (think Warhol)) that sells 4L plastic containers of it.

But if you want decent H2SO4 make it yourself, SO2 is formed by dripping bunneys bought muriatic on metabisulphite (home brew cleaner). Cl2 is formed by dripping HCl into hypochlorite (ie. domestos or homebrand version). Pass the SO2 gas into distilled water to form sulphurous acid (if you freeze & thaw it a few times it also oxidizes - the clathrates are funky as fuck) which is very endothermic. Pass Cl2 into the sulphurous acid to get H2SO4 and gaseous HCl (so getting two pure acids for the price of one if you pass the HCl into distilled water).

But that is QLD nowadays, everything is so fucking hot since the two major groups of f-wits with leather jackets and patches took to moving to the Sunshine state & pulling 80% of their pseudo runs there.

Be fucking careful if you try and import glassware or get anything by mail.

AusPost will NOT ship liquid corrosives. They are even funny about dry powders, especially strong oxidisers or toxic stuff. What's more, most businesses won't even offer to ship same through the post -- most offer only courier services, even for relatively innocuous things such as CuSO4.

For instance, my most recent chem order to Vanbar (photographic chemicals) had to be sent by courier. It was about $20AU for the courier, so I made sure to order lots of chemicals to reduce the pain a bit. (Unfortunately, Vanbar won't even ship GAA via courier; you have to go to their Melbourne location in person -- and, presumably, be obliged to give photo ID and perhaps sign an E.U.D.)

If you don't want to drop by Ace Chemicals, just go to someplace like Mitre 10, Reece Plumbing, or Banner Hardware (in SA). You'll find Momar "Mo Flo" drain cleaner sulphuric acid at about 90% concentration for about $45/litre. It's black and vile looking and it has some kind of corrosion inhibiters in it to protect pipes, but it should be usable for lots of reactions.

The problem I have with that statement is that although it might be true that CuSO4 would decompose to CuO and SO3, the reaction time might be very long.
The next problem is that those SO3 vapors need to be collected and people say that it is hard to condense and that it should be added to a medium concentration H2SO4 solution.

Have you done it?
Or has someone else done it?
Is the procedure practical?
What materials are needed for the container?

Also, note that venting sulfur trioxide into water instead of sulfuric acid would be catastrophic, IIRC.

The Supercheap Auto guy was talking out his arse. There are NO restrictions on H2SO4 in Australia, nor any need for EUDs or identity checks whatsoever.

As far as drain cleaner goes, why buy 1L for $50 when a 20L drum of 98+% pure costs $50 plus freight (maximum of another fifty, and that's if you don't manage to get it freaighted with a supply house's next order).

Just go to a cleaning chem supply house and ask for a 20L drum. Or PM me and let me know what state you're in, and if you're in mine I'll let you have some for free - the only reason I bought 20L was because it was the same price as 1L of adulterated shite.

Halcyon - 24-3-2012 at 18:23

Ok, I've had a couple questions from other Aussies, so I might as well post what I've found out here in the open.

For QLDers, try emailing info@avantichem.com.au or check out http://www.qldchemicalsupplies.com.au/

For NSW folks, try contacting one of the following:

http://www.truebluechemicals.com.au/
http://www.envirochemicals.com.au/

Just ask if they're able to supply concentrated sulphuric acid, what their lowest quantity is and how much. Remember that you're not doing anything wrong, don't make apologies or excuses if they ask what you want it for or tell you there's some restriction on it and you'll typically come off as a lot less suss
