Thioacetone

Hello,

I'm interested in buying/making thioacetone (the chemical that smells really bad)
Can anyone help me ?

Regards.

Don't.
Seriously, just don't.

Sheesh. Lately If it isn't somebody new asking for a "recipe" to make sodium cyanide it's this

Yeah what's next, fluorine because it looks neat?:P

How about Batrachotoxin because it's structure is kewl:D

First, you will isolate some impure thioacetone oil, and the stench will be bearable. When you recrystallize it and leave it to dry, the intensity of the smell will increase, and you will probably vomit. Your dog will cough up the squirrel he had for lunch, and the area near your house will be cleared of songbirds. When you stumble outside to get some fresh air, the wind will catch the air in your laboratory, and distribute a portion of the material to each of your neighbors. Merry Christmas. Thank goodness that they haven't eaten dinner, but that doesn't matter, because they probably won't be eating at home anyway after that. Your angry neighbors will go to torches and pitchforks, or more likely, the police, and then you'll have to explain to them why you made such a smelly material.

It's probably a bad idea.

Funny thing about this - the "thioacetone" (or whatever the exact odorant is) is perfectly harmless - unlike toxic chemicals, and explosives no physical harm can come to you - yet this looks like one of them most hazardous areas of experimentation for a home lab.

Compare say to an extremely toxic compound, say, a nerve agent.

The nerve agent will have its physical, chemical and toxic properties thoroughly documented, and the synthesis will be very well known (a lot of literature on this). Thus it is possible to design experiments such that very small amounts are produced and manipulated safely and the methods of dealing with any very small accidental releases straightforward and efficient. Though quite toxic per unit mass, that toxicity is well measured and bounded and can be managed.

None of this is true with "thioacetone".

If the exact identity of the odorant is indeed in doubt (check the other Thioacetone thread) then obviously its properties are not well understood. Little seems to be available about the reactions that produce it, since no one wants to make it. It seems to be harmful in extremely small amounts, with little indication of how low it might go. Decontamination seems difficult. There seem to be no grounds to design a sensible preparation even on the micro scale with predictable and controlled effects.

If you were running a macro (or maybe even a micro) scale reaction and stumbled upon really efficient reaction conditions for production of the odorant then heaven help you.

This is the sort of bad episode that could potentially get a house condemned and torn down if odor decontamination cannot be accomplished.

Consider the case of the USS Bistera, a destroyer escort that was contaminated by a few hundred grams of mustard gas after picking up men contaminated by a CW munition store explosion at Bari Harbor in WWII. Large amounts of decontaminating agents were used to try to remove the residual contamination left from the men's clothing, but were unsuccessful and the ship was scuttled.*

One could imagine a persistent extreme noxious odorant absorbed on the surfaces of a dwelling being impossible to remove.

*I should clarify - a few hundred grams was the total amount of bis(2-chloroethyl) sulfide brought aboard, mostly as clothing contaminant. After the clothing was removed and destroyed, and the areas where the men were housed washed down by decontaminating solution, the total residual contamination of the vessel from migrating vapor was no more than several grams. This is what they could not get rid of, and led to scuttling the ship.

This sounds like a good experiment to perform in the middle of the ocean before ditching the vessel you are on.
