METHOD FOR PRODUCING ALCOHOL AND CATALYST FOR PRODUCING ALCOHOL

WIPO Patent Application WO/2020/090756

A1

The present invention addresses the problem of improving the production efficiency of an alcohol obtained through the hydration of an olefin and providing high-performance catalyst used in the production of an alcohol obtained through the hydration of an olefin. The present disclosure provides a method for producing an alcohol by using a solid acid catalyst, supplying water and a C2-C5 olefin to a reactor, and performing hydration in a gas phase, the method being characterized by: kneading a fumed silica obtained by a combustion method, a silica gel obtained by a gel method, and a colloidal silica obtained by a sol-gel method or a water glass method; molding the resulting kneaded product; calcining the resulting molded body to obtain a silica carrier; and using a solid acid catalyst in which a heteropolyacid or a salt thereof is supported on the silica carrier.
