Procedure

In practice of the invention as set forth in FIG. 2, effluent from a reactor wherein debutanized isobutane oxidate comprised of tertiary butyl hydroperoxide and tertiary butyl alcohol is reacted with isobutylene to form ditertiary butyl peroxide is combined with an azeotropic ditertiary butyl peroxide and tertiary butyl alcohol stream and fed to dehydration zone 102 via line 101. Dehydration zone 102 is a reactor distillation column provided with a central packed bed 103 of zeolite H--Y catalyst supported by conventional means. Fractional distillation zones 104 and 105 are located respectively above and below the catalyst bed.
