ABSTRACT:
A process for preparing branched chain fatty acids or alkyl esters thereof comprising at least a step wherein unsaturated fatty acids having 10 to 25 carbon atoms, alkyl esters thereof or mixtures thereof are subjected to skeletal isomerization reaction in the presence of water or a lower alcohol at a temperature of 150.degree. to 350.degree. C. using a zeolite as a catalyst, the zeolite having a linear pore structure of pore size that is small enough to retard dimerization and large enough to allow diffusion of the branched chain fatty acids or alkyl esters thereof.
