Abstract
A tertiary butyl hydroperoxide reaction product is distilled to provide a tertiary butyl alcohol distillation fraction containing tertiary butyl alcohol and a heavier fraction containing unreacted tertiary butyl hydroperoxide, and reaction by-products boiling below tertiary butyl alcohol, the tertiary butyl alcohol fraction is charged to a vacuum distillation column for separation into a vaporized overhead tertiary butyl alcohol fraction that is cooled to obtain a liquefaction product containing a minor amount of vaporized tertiary butyl alcohol and a major amount of a liquified tertiary butyl alcohol, and the tertiary butyl alcohol vapors are dissolved in water to form an aqueous solution of tertiary butyl alcohol from which the tertiary butyl alcohol is recovered.
