WebThioacetone is an organosulfur compound belonging to the -thione group called thioketones, with a chemical formula (CH 3) 2 CS. It is an unstable orange or brown substance that can be isolated only at low temperatures. Above −20 °C (−4 °F), thioacetone readily converts to a polymer and a trimer, trithioacetone. It has an extremely potent, … Thioacetone is usually obtained by cracking the cyclic trimer trithioacetone, [(CH3)2CS]3. The trimer is prepared by pyrolysis of allyl isopropyl sulfide or by treating acetone with hydrogen sulfide in the presence of a Lewis acid. The trimer cracks at 500–600 °C (932–1,112 °F) to give the thione.

Trithioacetone (2,2,4,4,6,6-hexamethyl-1,3,5-trithiane) is an organic chemical with formula C 9H 18S 3. Its covalent structure is [–C(CH 3) 2–S–] 3, that is, a six-membered ring of alternating carbon and sulfur atoms, with two methyl groups attached to each carbon. It can be viewed as a derivative of 1,3,5-trithiane, with methyl-group substituents for all of the hydrogen atoms in that parent structure.
