TH1882B - Processes for producing alcohol - Google Patents

Abstract

The process for producing various alcohols is usually furfuril alcohol by using furfural to make a hydrocinate reaction. Or produce Fatty guys Various alcohols by hydrogens are fatty acids with the same number of carbon atoms. Or the esters of these acids Under pressure in the range from 20 to 100 bar at temperatures from 150 to 300C with a catalyst included, one part of the Cu-Cr mixture and the other copper coated on the support.
