Abstract

1334205 Fatty acid esters PROCTER & GAMBLE CO. 21 March 1972 [24 March 1971] 13120/72 Heading C2C Mixtures of alkyl (1-4C) esters of unsaturated fatty acids are enriched in the unsaturates by contacting with a two-phase solvent system comprising a liquid hydrocarbon and a homogeneous liquid lower alkyl sulphoxide-lower alcohol solution at a temperature within the range 0‹ to 110‹ F., separating the resultant sulphoxide-alcohol extract phase and hydrocarbon raffinate and recovering the esters from the extract. The alkyl (1-4C) esters are obtained by transesterification of a fat or oil with the 1-4C alcohol in the presence of mineral acids on a basic catalyst. Alkyl esters derived from soybean, safflower, corn, palm, tung, lard and tallow oil may be treated. Hydrocarbon solvents may be pentane, cyclopentane, hexane, octane, 3-methyloctane, hexadecane, cyclohexane, petroleum ether, kerosene and light mineral oil. A dimethyl sulphoxide and methyl alcohol in a weight ratio of 100:1 to 10: 6 may be used.
