Fatty acids are hydrogenolysed to correspond‐ing alcohols in 90% yield at 220‐250C at pres‐sures of 3500‐4000 psi. For saturated acids the catalyst is one per cent of copper and for oleic and ricinoleic acids 2% of copper and one per cent of cadmium, all present as their soaps. Only 10% of the unsaturation is lost. The main side product is the acid‐alcohol ester. In hydrogenoly‐sis of ricinoleic acid, the alcohol obtained con‐tains 15% of ester and 10% of lower alcohols such as undecenyl.
