Abstract

A process for effecting hydrogenolysis of a carboxylic acid ester comprising contacting a vaporous mixture containing the ester and hydrogen with a catalyst comprising a reduced mixture of copper oxide and zinc oxide at a temperature in the range of from about 75<o>C up to about 300<o>C and at a pressure in the range of from about 0.1 kg/cm<2> absolute (about 9.8 kPa) up to about 100 kg/cm<2> absolute (9813 kPa).
