Abstract:
A process for continuously producing tertiary butyl alcohol from water and a liquefied gas comprising isobutylene or an isobutylene-containing hydrocarbon using tertiary butyl alcohol as a solvent which process comprises reacting said water and said liquified gas in the presence of a cation exchange resin in a series multi-stage reactor, wherein the reaction temperature in each reaction vessel of the series multistage reactor is adjusted to not more than 65.degree. C., and wherein a part of the reaction mixture in the outlet of the first reaction vessel is returned to the inlet portion of the first reaction vessel at a circulation ratio of 1.8 to 10, and wherein the weight ratio of the tertiary butyl alcohol to the liquefied gas in the inlet portion of the first reaction vessel is 0.5 to 3.5.
