摘要： Phenol pitch obtained as a bottoms fraction in the distillation of phenol deriving from the acid hydrolysis of cumene hydroperoxide is treated to recover therefrom desired products consisting of phenol, alpha-methylstyrene, cumene and acetone, by introducing steam and the phenol pitch, into a reactor in a weight ratio of from 0.01:1 to 1:1, withdrawing from the top of said reactor a vapor phase comprising said desired products, withdrawing from the bottom of said reactor a liquid phase consisting essentially of compounds of higher boiling point than said desired products, and operating at a pressure of 4-12 Kg/cm.sup.2, at a temperature of 320.degree.-400.degree. C., as measured in the liquid phase, and with a residence time of 0.5-10 hours.
