Produce trithioacetone
Trithioacetone is a cyclic sulfur-organic compound, [(CH3) 2CS] 3, which I read has a pleasant odor and is used as a food additive.
I am testing with the manufacture of sulfur soaps and I would like to manufacture this compound to see how it really smells and how useful it is.
The process should not require high temperatures, as it will produce thioacetone in another way (the most stinking substance in the world).
As I have read, one way to manufacture it is this:
3 H2S + 3 (CH3)2CO -> [(CH3)2CS]3 + 3 H2O
Hydrogen sulfide and acetone, and hydrochloric acid or any other Lewis acid are required to catalyze the reaction.
Will this really work? How do I mix hydrogen sulfide with acetone and the Lewis acid?

The trimer apparently has an unpleasant odour. Thioacetone is unpleasant also.

You sure you want to do this?

I would recommend against it. It is supposed to be one of the most penetrating and evil smelling substances.
"It merely stinks. But it does so relentlessly and unbearably. It makes innocent downwind pedestrians stagger, clutch their stomachs, and flee in
terror. It reeks to a degree that makes people suspect evil supernatural forces."
That's not hyperbole. In 1889, a factory in Freiberg, Germany attempted to make thioacetone. Their "success" produced "an offensive smell which spread
rapidly over a great area of the town, causing fainting, vomiting and a panic evacuation."
If you're not part of the solution, you're part of the precipitate.

And yet it is sold as a food grade product for use in flavours and perfumes.

The monomer is- shall we say- problematic.

Here is a method I came across. Unless you live on a one man island please note the precautions they use or if not don't forget to report back to us
when you get out of jail.
