Document Type and Number:
WIPO Patent Application WO/2021/205900
Kind Code:
A1
Abstract:
Provided is a method for stably producing a high-purity alcohol for a long period of time when producing an alcohol through a hydration reaction of an olefin by using a heteropolyacid catalyst. Provided is a method for producing an alcohol in which a reaction product is obtained by supplying a raw material mixture containing water and an olefin having X carbon atoms (X is an integer of 2-5) to a reactor and subjecting the mixture to a hydration reaction by using a solid acid catalyst in which a heteropolyacid or a salt thereof is carried, wherein the content of an impurity olefin having Y carbon atoms (Y is an integer of 2-6, and X and Y are different) contained in the raw material mixture is at most 700 molppm.
