Source of potassium permanganate in Eastern Europe
Hi! Does anybody know a product commonly sold in Eastern Europe that contains KMnO4 (something among the lines of the Pot Perm form USA) and at what
kind of store it could be bought? At least in my country it is no longer present in pharmacies as it is considered a "drug precursor".

Maybe somewhere in Belarus it's still sold with less restrictions. At least here in Ukraine KMnO4 is on the list of controlled substances.
Edit: Maybe for your particular reaction there is a replacement oxidizer?

Poland - a country to the East of Germany, borders to the East with Lithuania, Belarus and Ukraine.
You can get it from the UK too, on Ebay.

Yeah, but I'm not polish. I would prefer to buy it from my country as I am too afraid to order it online from another country. (Just asking a
pharmacist if they still have it made them very suspicious)
All I could find was a really expensive 1N solution.
btw I am from Romania.

Only dichromates would also work, but I don't like handling such carcinogenic substances. I think that finding MnSO4 at a reasonable price could also
suffice as I can oxidize that to permanganate with sodium persulfate with silver nitrate catalyst.

nice attempt, but it is more like che fachi. Most of those companies don't sell to individuals anyway.

Strange.
I imagined the response would be 'Beeeneh'.
Funny how being drunk can make things clear at times.

Dichromate is really only carcinogenic if you decide to eat some or otherwise ingest it, you can look at a list of dangers for chemicals but these are
just possibilities. Unrelated to an extent, I bought some caffeine powder from a chem house since it was the only source available to me and it had a
warning that it was ‘harmful if swallowed’, which it obviously isn’t since many people consume it daily.
We used to use dichromate extensively for organic oxidations in school because of the colour change associated with the reaction, if it was massively
dangerous then it wouldn’t be allowed for students to use. Gloves and a mask will protect you just fine even if it’s a little excessive, and
don’t suck your fingers afterwards; long story short, you won’t get cancer if you treat it like any other chemical in your lab, there are far more
dangerous substances you’ll come into contact with during the course of experimentation.
In chemistry, sometimes the solution is the problem.
It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.

Do you have a procedure for this? I am not aware of any home chemists who have successfully synthesised KMnO4. I have easy access to MnSO4, Na2S2O8
and silver nitrate is not too difficult either. OTOH, KMnO4 is easily available where I live but not especially cheap.

Depending how much I have left and how much you need I could send you some. I think I can spare a couple hundred grams, I have to check but I think it
is technical quality..
I'm pretty sure I also have Na2S and a 250 ml Erlenmeyer.
Do you have some interesting stuff to swap? I don't need sodium metal.

Try eating 10g of your pure caffeine powder and then tell me it's not harmful if swallowed...

There is a video on YouTube on this https://youtu.be/xNBNpBhBVM4
I know woelen explains it as well on his website, but I can't seem to find the exact page on this.

Well I don't have very exotic reagents. I have some analytical grade ammonium nitrate, potassium hydroxide, diethyl ether, barium chloride. I also
have technical grade trisodium phosphate. Everything else I have is pretty otc (50% hydrogen peroxide, concentrated sulfuric acid etc. ) or is easily
made (nitric acid etc.) . I could buy some exotic reagents from a chemistry shop in my country if you'd like to swap for the sodium sulfide at least
(that's the one I want the most).

There is potassium pormanganate crystals in every pharmacy in Bosnia and Herzegovina. Comes in i think 50 or 100 ml brown glass bottle. I bought it
when i was underage 5 years ago. Until I decided to stop wasting money on chemistry, and try to earn it that way instead.

50% H2O2?!
Where did you get that?

From the chemistry shop I was talking about in my earlier post. It sells a lot of nice reagents, even potassium tetraiodomercurate for example. But
some normally otc reagents aren't in their catalogue, such as cheap hydrochloric acid or potassium permanganate more concentrated than 1N.

It isn't this way in Romania anymore. It is no longer sold in pharmacies.

It might be worth your effort to enquire as to whether they can source some potassium permanganate for you - there are a whole plethora of uses for
it, including as an antiseptic, fungicide, treatment for various skin conditions, as a survival tool - starting fires using glycerin/ethanediol and
water, water purifier/disinfectant, and to mark snow if you get lost. It can also be used to disinfect aquariums for sensitive fish, as a nutrient for
growing vegetables, and to treat disease in your garden.
It is such a useful chemical that banning it for the sake of curbing drug manufacture is utterly insane! It would be like banning diethyl ether,
hydrogen peroxide, ammonium nitrate, and even water just because they can be used for illicit purposes even though there are far more
numerable legitimate and totally legal uses. Good luck on your quest to source some.

Thank you! Even my grandma thinks it's insane to ban it. She used it for disinfecting fruits, but now she can't.
