PRECIPITATION OF MOLYBDENUM (Docket No. 81,003-F) ABSTRACT OF THE DISCLOSURE An epoxidation reaction product formed by the molyb- denum catalyzed reaction of propylene with tertiary butyl hydroperoxide to provide propylene oxide and tertiary butyl alcohol is separated by distillation into a propylene frac- tion, a propylene oxide fraction, a tertiary butyl alcohol fraction and a heavy liquid distillation fraction composed primarily of tertiary butyl hydroperoxide, tertiary butyl alcohol, dissolved molybdenum catalyst, and impurities including lower aliphatic C1-C4 carboxylic acids, and the heavy liquid distillation fraction is saturated with hydro- gen to precipitate the molybdenum therefrom for recovery.
