ABSTRACT:
An aqueous methanol feed stream contaminated with tertiary butyl alcohol is charged to a reactive distillation column having a reaction distillation section in the upper portion thereof containing an acid cation exchange resin and separated therein into a substantially anhydrous lower boiling methanol fraction contaminated with isobutylene and a higher boiling water fraction by charging the feed stream to the lower portion of the reactive distillation column to separate the feed stream into a higher boiling water fraction and a lower boiling methanol fraction containing a tertiary butyl alcohol-water azeotrope for upward flow into the reactive distillation section for reaction of the tertiary butyl alcohol to form isobutylene, MTBE and water and recovery of a substantially anhydrous lower boiling methanol fraction contaminated with isobutylene and MTBE.
