METHOD FOR PRODUCING TERTIARY BUTYL ALCOHOL

摘要

Disclosed is a method for producing a tertiary butyl alcohol wherein the hydration rate of isobutylene is high. Also disclosed is a method for producing a tertiary butyl alcohol wherein a low-concentration isobutylene is used as a raw material and the hydration rate of isobutylene is high. In this method, a tertiary butyl alcohol is produced from isobutylene and water in the presence of an cation-exchange resin catalyst and at least one solvent selected from the group consisting of sulfones and organic carboxylic acids, using a reaction distillation apparatus. Preferably, at least one solvent selected from the group consisting of sulfolane, dimethyl sulfone and acetic acid is used as the solvent in this method.
