Web7 Sep 2024 · How do you make Thioacetone? 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.
