Abstract
C.sub.8-22 fatty alcohols are produced by a process which comprises contacting a triglyceride with hydrogen in the presence of a copper-zinc catalyst and in a reaction zone. The hydrogen pressure in the reaction zone is from about 200 to about 280 bar, the temperature of the entrance of the reaction zone is from about 200.degree. C. to about 230.degree. C., and the temperature of the exit of the reaction zone is from about 190.degree. C. to about 220.degree. C. The amount of 1,2-propanediol formed is optimized by the lower temperature of the exit portion of the reaction zone.
