Abstract

Primary alcohols are prepared by reaction of an organic compound containing olefinic unsaturation with carbon monoxide and hydrogen in presence of a hydrogenation catalyst at above 300 atmospheres pressure and a temperature above 250 DEG up to 400 DEG C., preferably 325-1500 atmos. and 275-375 DEG C. The molar ratio of olefinic compound: CO : H2 is suitably between 1 : 2 : 2 and 1 : 5 : 20. Suitable olefinic compounds and general conditions of reaction are as specified in Specification 614,010. Copper with aluminium and/or cobalt is preferred as catalyst. Preheating in hydrogen or partial poisoning with sulphur prevents hydrogenation of olefins to alkanes. In examples, propylene is converted to butanols, and ethylene to propanols using catalysts comprising 1Cu : 0.1 Cr : 0.05 Co, 9 Cu : 1 SiO2 or 1 Cu : 1 SiO2 pressure being 1000 atmos. Aldehydes, esters and acids in the products may be reduced to alcohols by hydrogenation. Specification 637,999 also is referred to.
