Process for the preparation of tertiary butyl alcohol.

摘要

A process for preparing tertiary butyl alcohol from isobutylene comprising reacting isobutylene or a hydrocarbon mixture containing isobutylene with an aqueous solution of an aliphatic carboxylic acid having from 1 to 6 carbon atoms in the presence of a solid, acidic ion-exchange resin as catalyst to produce an aqueous reaction mixture of a major a mount of tertiary butyl alcohol and a minor amount of the tertiary butyl ester of the carboxylic acid, characterised by the steps of… (1) subjecting said reaction mixture (4) to distillation (103) to remove unreacted isobutylene or hydrocarbon mixture therefrom, and thereafter;… (2) supplying the treated reaction mixture of step (1) to a distillation column (104) and passing water (9) downwardly through said distillation column (104) to remove said tertiary butyl ester of the carboxylic acid.
