Abstract

1334204 Fatty acid esters PROCTER & GAMBLE CO 21 March 1972 [24 March 1971] 13119/72 Heading C2C Mixtures of alkyl (1-4C) esters of unsaturated fatty acids are enriched in unsaturates by contacting with a two phase solvent system comprising a liquid hydrocarbon and γ-butyrolactone at between 0‹ and 110‹ F., and separating the butyrolactone extract 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 or a basic catalyst. Alkyl esters derived from soybean, safflower, corn, palm, tung, lard and tallow oil may be treated. Hydrocarbon solvents may be hexane, octane, nonane, hexadecane, cyclohexene, petroleum ether, kerosene and light mineral oil.
