Document Type and Number:
WIPO Patent Application WO/2021/166485
Kind Code:
A1
Abstract:
A method for producing an alcohol by hydrating an olefin using a heteropolyacid catalyst is provided, in which the catalyst can be stably used over a long period. The method is for producing an alcohol by supplying water and an olefin having 2-5 carbon atoms to a reactor and hydrating the olefin in a gas phase using a solid acid catalyst loaded with a heteropolyacid or a salt thereof, and is characterized in that a raw-material mixture to be supplied to the reactor has an aldehyde compound content of 70 mol ppm or less.
