| titleOfInvention | Improved process for fractionating highly unsaturated fatty acids from less unsaturated and saturated fatty acids |
| abstract | Mixed fatty acids or their glycerides, particularly of the semi-drying oil class, are separated according to their unsaturation by treating the sodium soaps thereof in suitable particle size with a water-miscible organic solvent consisting of an aliphatic monohydric alcohol or water-containing aliphatic ketone in which the soaps of the saturated fatty acids and those with one double bond are insoluble and the soaps of the highly unsaturated fatty acids are soluble. After removal of the solvent from the extract, the soaps in each case may be acidified to obtain the saturated fatty acids and acids of low unsaturation on the one hand, and highly unsaturated fatty acids on the other hand. The former may be used directly as soaps, acidification being then unnecessary; the latter, after acidification, may be esterified with glycerine or pentaerythritol to obtain drying oils. The oils specified to be treated comprise soybean oil, liver oils, sardine, herring and other marine oils. The solvents specified comprise methanol, ethanol, isopropanol, acetone and methyl ethyl ketone. The extraction is preferably a continuous counter current extraction and may be carried out in steps, by which the soaps of the highly unsaturated fatty acids are extracted first and then the soaps of the fatty acids of lower unsaturation are extracted, leaving the saturated acids and the acids of lowest unsaturation undissolved. |
