Sn2 on thioacteone
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. Web3 Jul 2024 · The trimer of thioacetone [...] with a melting point of 24 °C, near room temperature It will dissipate into the atmosphere very easily. It was also found "that dilution seemed to make the smell worse". Note as the side-box on that page states, the melting point of thioacetone itself is 40 °C.
