In the EU, a private individual cannot buy H2SO4 above 15%. Battery acid is 38% H2SO4 and can therefore only be purchased by companies and only be filled into batteries by companies. Companies are only allowed to sell this battery acid in batteries or they have to fill the acid into the battery. Submission is not permitted.
Sad.
You can make H2SO4 from gypsum lmao.
Bakers ammonia + CaSO4 liberates ammonium sulfate and calcium carbonate.
Ammonium sulfate can be turned into sulfuric acid by using a special electrolytic bath.
You get watery ammonia as a side-product.
The EU has a massive skill issue.
@@cezarcatalin1406but,but,,all the 'cultural enrichment and diversity' was suposed to be our strenght! 😅 Kids don't get taught sxxt at school compared to 30, or 40 years ago. Cuntinual assessment, with emphasis on the ass......😮😊
@@cezarcatalin1406 No skill issue at all. More of a "everyone knows how but nobody's stupid enough to admit to illegality on the internet" issue that makes you think nobody in the EU is doing it.
@omegageek64 do you have a link or post a copy of your conversion chart please
Sulfuric acid doesn't form an azeotrope but it does form a constant boiling mixture at 98.3%. To get above 98.3% you have to add sulfur trioxide. But most people can use 92% or higher as concentrated. The 85% is the monohydrate and anything above that is dehydrating and will absorb water from the atmosphere.
For oleum (above 98.3%) just make sodium acid sulfate, heat it up to liberate water thus turning it to pyrosulfate then heat it up further to liberate sulfur trioxide.
Na2SO4 + H2SO4 -> 2 NaHSO4
2 NaHSO4 -(heat)-> Na2S2O7 + H2O
Na2S2O7 -(400C)-> Na2SO4 + SO3
Another method that turns almost 100% of the H2SO4 into SO3 without needing heating to 400C is reacting Tin(IV) chloride with H2SO4 to make anhydrous Tin(IV) sulfate and lots of hydrogen chloride. Then heat up the Tin(IV) sulfate to liberate SO3 and leave behind Tin(IV) dioxide. Here’s the general reaction:
Sn + 2 Cl2 -> SnCl4
SnCl4 + 2 H2SO4 -> 4 HCl + Sn(SO4)2
Sn(SO4)2 -(180C)-> SnO2 + 2 SO3
SnO2 + 2H2 -> Sn + 2 H2O
The hydrogen and the chlorine can be produced simultaneously in a chlor-alkali electrolytic cell.
NaCl + H2O -> cathode{NaOH + 1/2 H2} + anode{1/2 Cl2}
Best part about this method is that you start with table salt and H2SO4 and you end up with NaOH, HCl and SO3 (and some water but no one cares about that). The tin metal is recycled in this process.
5:08 there's always a workaround....
Single best way to get me to do anything is to tell me I can't 😅😂
All my H2SO4 is homemade at no cost. My anaerobic digesters produce free methane gas for heating of liquid chemical solutions, and the biproduct is H2S. This hydrogen sulfide is captured and converted to elementary sulfur, which is the starting material for making H2SO4.
Another source is "waste material" from scrapping: Rubber seals, rubber plugs/bushings all contain sulfur. So do bicycle-, motor bike-, and car tyres (around 5%). All rubber is pyrolyzed, and later when the raw pyrolysis oil is refined the sulfur is removed as a useful biproduct.
Sulfur is also obtained by thermal decomposition of waste gypsum (drywall waste from demolitions, or cut offs from construction).
can you explain more how you get a biproduct of H2S from methane (CH4)? what other chemical does the sulfur come from?
I think I'm misunderstanding something.
@@divinezoomer7305. Let me elaborate the comment a bit further. I never buy any chemicals; virtually everything needed for metal recovery and refining is homemade at no cost at all.
H2S occurs naturally in anaerobic digesters (partly responsive for the rotten smell). It must be removed from the methane as it's highly corrosive and spoil all gas burners. Easily captured as elemental Sulfur by adsorption.
Sulphur can also be obtained from the "stinky" oil from any kind of rubber processed by pyrolysis. Lots of Sulfur can be extracted from thermal decomposition of waste gypsum. The yield is high, but the process requires building a slightly advanced apparatus yourself.
Part of my Sulfur is converted to SO2 for precipitation of PMs, part of it is converted to H2SO4. Both conversions are not suitable for amateurs, or home refiners without deep insight in chemistry! Be aware, when converting Sulfur to H2SO4 the process is extremely HOT.
Great video! The most basic method I know is to burn sulfur and bubble the smoke through ice water to create a weak H2SO4 solution.
Two improvements. Use a thermometer to measure boiling temperature, that will tell you the concentration. Secondly, when you have removed most of the water move to a flask with a short reflux condenser to reduce the acid fumes.
this is just a caution: Yes, it is Florida and hot and humid but you should wear full body protection and a full face shield. One for accidental splatters and related to gold recovery, even a small amount of PGM salts on your skin could result in an incurable heavy metal poisoning from platinum called platinosis
I agree with platinosis I'm almost certain Sreetips says it can or does lead to blindness!?
I have special spark plugs with 8 tips in all and I'm assuming they're a platinum or some other pgm but not sure what?! So I'm a bit apprehensive of recovering it unless I can confirm what it actually is
your statement about the politics is absolutely true! Thank you for the video.
Hold the battery acid bottle vertically with the opening at the upper end. Then rotate, around the centerline of the opening, the bottom of the container to the horizontal, and above. That will minimize / eliminate the sloshing of the fluid.
Absolutely nailed it brother awesome work
Best hurry up and stock up on that Bisulphate salt because that will be next.
Be a good idea to have some baking soda dissolved in water do neutralize if you get any on you or spell it
Looking at the struggle couldn't you use the vacuum pump to reduce the pressure and boil off the water using a lot less heat
vacuum will reducing boiling temp of conc. H2SO4 but it will still need to be over 200°C
You could, but the acid would destroy the pump
@@edrimeikis9270 use an asperator 😉
The added risk of implosion is generally considered not worth the risk.
For more accurate measurements, consider filling the graduated cylinder using the bottom of the fluid meniscus as opposed to the top of the fluid line. 😉
and check the accuracy of the cylinder too
Maybe if you put a P trap in your blower stack before the blower it would make your blowers last longer.
When the law in Germany/EU changed last year, Thyzoid did a video about it. He had several gallons of concentrated sulfuric acid he had to dilute with water.
Sad.
He actually dissolve it? I would just lie
@@NilaSpeaksLoudly Depends on your tolerance for having your life turned upside down by corrupt authorities- ua-cam.com/video/z1Qe7NrBXJU/v-deo.html
Listen I live in England and as long as you mix your nitric acid with 3rd hcl making AR is not illegal so soon as you make nitric turn it into AR. Also sulphur is widely available so sulphuric acid is easy to make.
make a zinc acid-air (znso4 water) electroplating zinc-air battery instead, it will recharge to zinc + h2so4 water, from the steel/zinc + carbon/air electrodes
you could also just boil dilute h2so4 to absolute h2so4
In Canada, concentrated sulphuric acid (reagent grade) is available from chemical suppliers and also drain cleaner, but you have to look around.
Or anyplace that deals with batteries ... Like ( Canadian Tire... Dunno if they still carry the concentrate ... Been a few years )
You mentioned _”A.R.”_ for refining gold. (Not the only kind of _”A.R.”_ they want to ban.)
Back in the day when I was growing up, it was the *GOLD* itself that we were forbidden to own (here in the USA)!
Of course, back then, in high school chemistry labs, they had these nice little coasters to put hot glassware on to prevent damage to the tabletops - made of *ASBESTOS!*
And I remember the little poem we used to recite:
"Sally used to drink.
Sally drinks no more.
For what the thought was H20,
Was H2SO4."
You can boil it more rapidly! H2SO4 boils at 300 C !
What about boiling under a partial (relatively high) vacuum? Aspiration apparatus. also, install an updraft blower in your fume hood to preserve your blower.
Good job my friend! I may be over simplifying my hypothesis but could you add water to kill the efficiency of the anti-freeze and then simply freeze it? Remove the ice (majority of the water fraction) and then use the distilation process to bring it up to the desired 98%? Except for the freezing thought, I have always done it this way myself. Thanks so much you creative genius
Not sure. Have to research that. Thanks for the suggestion.
In the UK im sure homebase sell "spirit of salts" which I suspect is either hydrochloric acid or sulphuric acid
it's hydrochloric @36% but latest update to the poisons and explosives precursors last week the legal limit was reduced to 10% 😭😭😭
Unless you're a plumber
@@DorsetMushroomHunteramazing how we didn't even notice sliding from the nanny state, to full on tyrannical police state, isn't it?! Bit of division and distraction, and those supposedly working for us, are ruling over us, with ever increasing draconian powers......
Oh my days, I didn't realise this, I think I will need to get a epp licence.
Good afternoon, I enjoy your videos and clearly your knowledge is quite diverse therefore i would like to know if you have a low tech method of removing sodium fluoride from water
Distillation, reverse osmosis
Love this series very informative 👍🏻
Hi Mike, Wow! Great results! But you sure did make a mess!! :) I guess I'm really lucky having a major chemical supply house fairly close! Thumbs up! Stay safe!! Jim
Just a thought but I leave my fume hood fan on all the time. Figure the cost of electricity is less than a new motor. Besides as a smoker it helps pull the smoke out of the shop.
Places like autozone actually are charging more for most things too. So something like RockAuto may have it even cheaper. But that matters more for car stuff than getting this acid lol
Drain cleaner at 90+is good for most applications but might need to get rid of inhibitors with some oxidation. Many methods
Love your channel I’m in Australia and they also use it here for cleaning pools and is 35%. 15 litres was $35 AUD so about $20 USD. Hope that helps
What do they sell, whats the name of it plz
@@snoddyification hi mate pool shop online
I’m trying to send you the photo off product and website but can’t if you in Australia Google sulphuric acid. Then go to shopping tab
Yeah it’s poolshop online. Go into chemicals then Sulfuric acid 34%
@@markgellie7032 thanks.
I have had to filter and evaporate down with lead contam remaining.
Only useful for nitric synth, but toxic lead byproducts.
Extra note:
When re-perposing a storage jug,
Any durable HDPE container should
work well as you said... yet,
Ahead of time, test the material of
both the cap & cap's gasket.
(May want to have gasket materials
on hand, & not just for this)
Mf this guy is just great. Absolutely outstanding rant my guy.
Should have acid goggles and chemical bib on.
Oop were going in the other direction. This guy playing around here. "Now were cooking with gas" this kind of reminds me of the comic strip Crankshaft. He would run over Keestermans mail box with his school bus,.His inagural summer bar- b-cue's could be seen lighting up from as far as the moon.
Molecular sieves not help any? Not sure if they're safe to use with acid right enough 🤔 lol
I bet if you contained the process with a desiccant and ran it at a lower temperature you'd dry it with less loss.
Potentially a dumb question, but what might happen if you put the acid into your desiccation bucket that you rigged for the KNO3? Would it make HCL or cause some other unexpected reaction?
Sulfuric acid is a much more powerful desiccating agent than calcium chloride. I'd get dry calcium chloride crystals and dilute acid.
Acetone and hcl and h2so4
The Amazon acid looks like the ones you get with motorcycle 🏍 batteries 🔋 they come dry without fluid or used to. I'm afraid my information is sadly out of 📅 date. The spout makes it easier for use with the small 🕳 fill holes in such a 🔋 battery.
Motorcycle shops do acid for batteries usually as would scrapyards emptying batteries
New batteries supplied to the public do not contain any acid now.
@@DorsetMushroomHunter? It's a lead/acid battery! Won't work without the acid.......what are putting in it now? Vinegar grade acetic?!😅😊
@@keithcarpenter5254 you have to take it to a garage to fill.
I work at a recycling center. My boss can't buy batteries legally. This precious metal's. (Catalytic Converters, gold, I'm not sure even titanium) ammo brass ammo shells need to be fully checked for un-spent rounds. This subject this guy is touching on is hairy. Let's hope the FBI doesn't get involved. Dangerous but useful info. I Was born in 1963. I still remember chemistry sets sold at toy stores. You can't get plastic model cars at the drug store anymore. The kids sniff the glue.
Thanks for sharing
You can make a air scrubber with a plastic (or lined) drum that has a removable lid that has 2 @ 2" bung holes.
2" pvc piping
Few framed window screens
Imagination
Instead of blower,
2" pvc T & 2 @ shop vac.s
Will make a bit of difference
You can make more concentrated nitric acid without the hassle of concentrated sulfuric acid. Use sodium bisulfate instead. If you start with the ingredients dry, you can make fuming nitric acid if you want. Here is video. This is much safer & less hassle & chemicals are easier to get.

Maybe you can also help us to know how to make something like Eco-Goldex, so we don't need to use a lot of kind chemicals😁
Why did you not use a hydrometer for the specific gravity?
Do you have a link for the conversion sheet please @Omegageek64
Wonder if this is going to involve some car batteries, now for a bucket of baking soda lol!
An old name for sulfuric acid was Oil of Vitriol.
How comes there is no fuming mist when distilling it?
Can acid recovered from scrap batteries be used to concentrate . Will the lead cause problems .?
It will probably be contaminated with lead sulfate. I'm not sure if there's a way to remove it, but if you have glassware, you can distill it. You heat it in an open container like in this video, then once it starts smoking, you let it cool, then transfer it to your distillation apparatus.
The lead sulfate will drop out of solution if the acid is dilute enough, but that kind of defeats the purpose. I expect it would stay behind during distillation.
@@omegageek64 thanks have access to a lot of acid from auto batteries being recycled would like to put it to use in some way would be good to somehow drop lead out and have useable acid without distillation or find a use for lead contaminated solutions
Wonder if putting a dehumidifier in with it you could reduce water with less acid loss? Without using heat.
yes if that dehumidifier contained Phosphorous phentoxide otherwise not a chance
@@DorsetMushroomHunter *phosphorous pentoxide
You got the Walmart nitric bottle
I do enjoy your videos, however I do feel that this is sort of clickbait. You're not making sulphuric acid, your concentrating sulphuric acid that you have bought. I live in the UK and you cannot buy battery acid like you have, to buy and own sulphuric acid (as nitric acid) you have to have a EPP licence, if you don't have a license, the maximum percentage is 15% so it's not easy to get, unless you recover it from used batteries, but then you have lead sulphate.
Or on clothing!
10:08 don't let those Nanny state tree huggers see that you printed out a physical copy on deceased remains of victimized trees or they'll be all over your front lawn trampling and salting it up with tears.
No not even battery acid can be legally sold to the general public.
Sad.
You can still get epsom salt, you can make it.
You seem to have arm protection 😅
IV just watched the video twice and I've only just realised the proff is a bloody orangutan!!! He could do with splashing it all over to remove the ginger arm fur😂😂😊
Why would you not adjust the temp down to between 100 C-150 C this over a long period of time boils off the H2O but not reach boiling point of H2SO4 which is 300C
A video nearly an hour long that tells you if you want to concentrate weak acid you have to heat it to evaporate the water
No shit Einstien😂😂😂
Absolutely correct. That is why I haven't subscribed - same with the video for making Potassium Nitrate from Potassium Chloride and Calcium Nitrate. It is a double decomposition reaction 2KCl + Ca(NO3)2 -> 2KNO3 + CaCl3 and since KNO3 is sparingly soluble in cold water it precipitates out and the highly soluble Calcium Chloride remains in solution.
Another one is making Ammonium Nitrate from Ammonium Sulphate and Calcium Nitrate - in this reaction Calcium Sulphate is precipitated and Ammonium Nitrate remains in solution.
So this channel has a low signal to noise ratio.
With every step you demonstrate just why governments legislate against personal possession of chemicals. You sir, seem like a nice guy, but you are a danger to yourself.
