ABSTRACT:
A process for the production of fatty acid mixtures containing a high proportion of C.sub.6 -C.sub.10 -fatty acids consisting essentially of (1) transesterifying mixtures consisting essentially of C.sub.6 -C.sub.10 -fatty acid alkyl esters with from 1 to 4 carbon atoms in the alkyl with glycerine at 160.degree. to 250.degree. C. in the presence of transesterification catalysts with removal of the C.sub.1 -C.sub.4 -alkanol formed, (2) adding the C.sub.6 -C.sub.10 -fatty acid glycerides to a C.sub.6 -C.sub.18 -fatty acid glyceride selected from the group consisting of coconut oil, palm kernel oil and mixtures thereof, (3) subjecting the mixture of glycerides to lipolysis in the presence of an excess of water at 200.degree. C. to 250.degree. C. at the autogenous pressure in the absence of a catalyst until until the required degree of splitting is achieved and (4) recovering a fatty acid mixture containing a high proportion of C.sub.6 -C.sub.10 -fatty acids.
