Abstract

Provided is a method for producing an alcohol through an olefin hydration reaction using a heteropolyacid catalyst, the method enabling the catalyst to be stably used over a long period. In the olefin hydration reaction, in which the heteropolyacid catalyst is used, the pressure loss during the period of passing a feed-material gas through a catalyst layer is regulated to a certain value or less. Specifically, the method for producing an alcohol comprises using a solid-acid catalyst including a supported heteropolyacid or salt thereof, supplying water and a 2C-5C olefin to a reactor, and hydrating the olefin in a gas phase, wherein the pressure loss during the period of passing the feed-material gas through a layer of the catalyst is regulated to 350 kPa or less.
