ABSTRACT:
Tertiary butyl hydroperoxide and tertiary butyl alcohol are recovered from the reaction product formed by reacting excess propylene with tertiary butyl hydroperoxide in solution in tertiary butyl alcohol in the presence of a soluble molybdenum catalyst, by fractionating the reaction produce to provide distillate propylene, propylene oxide, and tertiary butyl alcohol fractions and a heavy distillation fraction comprising tertiary butyl hydroperoxide, tertiary butyl alcohol and impurities, including dissolved molybdenum catalyst, the tertiary butyl hydroperoxide and tertiary butyl alcohol being recovered from the heavy distillation fraction by vacuum evaporation under evaporation conditions including a temperature of about 25.degree. to about 160.degree. C. and a pressure of about 2 to about 200 mm Hg. in order to provide a lighter condensate fraction comprising about 60 to about 95 wt. % of the heavy distillation fraction and containing from about 70 to about 95 wt. % of tertiary butyl alcohol, about 1 to about 20 wt. % of the tertiary butyl hydroperoxide and from about 15 to about 3 wt. % of impurities and also into a clear liquid heavier residue fraction comprising tertiary butyl alcohol, tertiary butyl hydroperoxide and substantially all of the soluble molybdenum catalyst originally contained in the heavy liquid fraction.
