1978. ------. [KYOWA CHEMICAL ENTERPRISES CO.] [Preparation of Aliphatic Saturated Alcohols From Carbon Dioxide and Hydrogen.] Japanese Patent 162,927, Mar. 15, 1944. Chem. Abs., vol. 41, 1947, p. 5142.

Mixture of 1 part each of Mn, Cu, and Zn hydroxides, 0.2 part Fe₂O₃, and 0.125 part KOH (the oxides or carbonates of each may be used, Cr may be substituted for Cu, and another alkali metal for K) is dried into bean-sized lumps with the addition of kieselguhr and then dehydrated at 400° and reduced in H₂ gas just before use. The CO₂-H₂ mixture, CO₂25.5%, is heated in the presence of this mixed catalyst at 400° per 150 atm. The resulting liquid, after distilling off the H₂O, refining with CaO and KOH, and desiccating, is fractionated into 39.5% EtOH, 33.5% PrOH, 8.3% iso-BuOH, and 18.7% MeOH. The total alcohol yield is 53 cc. from 3.45 1. of gas mixture.
