Procedure

The oily material from the distillate weighed 48.5 g. and consisted of 26% cumene, 56% α-methylstyrene and lesser amounts of acetophenone and cumyl alcohol. This recovered material was used without purification in a subsequent run from which a 55.1% yield of dicumyl peroxide was obtained.
