Abstract
A process for the isolation and purification of essentially fatty acid mixtures, which in addition to the methyl branched fatty acids contain saturated and unsaturated, respectively straight chain as well as methyl branched, unsaturated fatty acids, in which the industrial fatty acid mixtures are first hydrogenated by catalysis and then the methyl branched saturated fatty acids are separated, and in which before the hydrogenation if necessary, a separation by the hydrophilization process is provided, this process produces the desired products with a high yield and purity.
