TH2422A - Processes for producing alcohol - Google Patents

Abstract

A process for producing different types of alcohol is usually furfuril alcohol by using furfural to make a hydrocinate reaction. Or produce the Fatty Various alcohols by hydrogenate fatty acids with the same number of carbon atoms. Or the esters of these acids Under pressure ranges from 20 to 100 bar at temperatures ranging from 150 to 300C with a catalyst included, one part of the Cu-Cr mixture and the other a copper coating on the support.

Claims (2)
