Abstract

Aliphatic alcohols containing from 6 to 22 carbon atoms in the molecule are produced from starting materials containing at least one free fatty acid containing from 6 to 22 carbon atoms by a process comprising thermally esterifying the acid or acids with an alcohol containing from 6 to 22 carbon atoms in the molecule or a mixture of such alcohols, used in a proportion of at least 5 per cent in excess of the stoichiometric at a temperature above 150 DEG C. and at such a temperature and pressure that the alcohol is below its boiling point and the water formed is expelled as steam, and thereafter subjecting the product to hydrogenation in the liquid phase at elevated temperature and pressure in the presence of a foraminate copper catalyst in continuous manner. Suitable fatty acids are those obtained from natural oils and fats. In addition to the acids, glycerides and/or higher alcohols may be present in the mixture. The preferred foraminate catalyst is foraminate copper/aluminium formed from an alloy of copper and aluminium in the proportions by weight of from 40:60 to 80:20. In the examples palm oil is esterified with C8-C18 alcohols and the crude ester is hydrogenated according to the process of the invention to give C8-C18 alcohols.
