Participants

Reaction Steps

To a mixture of 10.18 g (0.082 mole) of 2,3-dimercapto-1-propanol, 20 mL of cyclohexane, and 5.0 g (0.086 mole) of acetone was added 4 drops of concentrated hydrochloric acid, and the mixture was stirred at reflux temperature for 3.5 hours to give, after fractional distillation of the reaction mixture, 5.85 g of a colorless oil, bp 96°-106° C./1.2-1.5 mm Hg, which solidified on standing. Recrystallization from toluene-hexane gave 3.96 g of product, mp 45°-50° C.
