1977. KYOWA CHEMICAL ENTERPRISES CO. [Aliphatic Saturated Alcohols With More Than Two Carbon Atoms From Hydrogen and Carbon Dioxide.] Japanese Patent 154,318, Dec. 21, 1942. Chem. Abs., vol. 44, 1950, p. 1525.

CO₂ and H₂ can be condensed at high temperatures under high pressures to aliphatic saturated alcohols according to nCO₂+6nH=CnH_2n+1OH+(2n-1)H₂O in the presence of MnO [Mn-(OH)₂ or MnCO₃] mixed with Fe oxide (hydroxide or carbonate) and a Cd, Cr, Al, Cu, or alkali metal oxide, singly or in combination. For example, over 300 cc. of a dried granular mixture of Mn (OH)₂, Fe (OH)₃, Cd(OH)₂, and CuOH (5:1:2:5 mol.), after heating at 400° in a stream of H₂, was passed H₂ mixed with CO_2, 24.7% at 397°-400°/150-160 atm. and space velocity 1,500 to give a liquid, which, after dehydrating by distillation was fractionated into EtOH, PrOH, BuOH, and MeOH, yields 20%, 18%, 8%, and a small amount respectively.
