Abstract

Saturated aliphatic monohydric alcohols are produced by reacting one mole of an acetylenic diol of formula:- <FORM:0936321/IV(a)/1> in which R1, R2, R3 and R4 are hydrogen or a C1 to C6 alkyl group, with three moles of hydrogen at a pressure of 1-5 atmospheres, a temperature of 20 DEG -100 DEG C., and in the presence of a catalyst containing rhodium or a mixture of rhodium and palladium. The catalyst is preferably supported on an inert carrier. The acetylenic diol may be used in solution in an aliphatic alcohol having up to six carbon atoms, or in an aliphatic acid having up to six carbon atoms. Diols used include butyne-2-diol-1,4 and 3,6-dimethyloctyne-4-diol-3,6 to give butanol and dimethyloctanol respectively.
