Abstract

PURPOSE: To obtain the title compound with a low water content, by passing tertiary butanol formed by selective hydration of isobutylene in mixed olefin into the upper layer almost free from water.
CONSTITUTION: A mixed olefin containing isobutylene and n-butene, and water are reacted, at a sufficient pressure for both of them to remain liquid of higher, in the presence of a heteropoly-acid having Mo, W, and V as condensation coordination elements, e.g., tungstosilicic acid, and a sufficient amount of tertiary butanol in the reaction system, to form a two liquid-phase reaction product consisting of the upper layer containing the tertiary butanol corresponding to the hydrated isobutylene and the remaining hydrocarbon, and the lower layer containing the heteropoly-acid, water, and tertiary butanol in the amount corresponding to that before reaction. The upper layer is separated to remove the hydrocarbon, and an aqueous solution of the tertiary butanol is obtained in a high concentration.
