Abstract

1444551 Edible oils UNILEVER 15 Oct 1973 [18 Oct 1972] 48039/72 Heading C5C The combined-polyunsaturated fatty acid content of an edible oil having a combinedlinoleic acid content of at least 50 wt. per cent based on the weight of the total combined fatty acids within this oil is increased by contacting the oil with a N-substituted amide (wherein all the available positions on the N atom are substituted by alkyl groups) solvent at a temperature at which two liquid phases are formed, and separating the phases, the one comprising a fraction of the oil rich in combined-linoleic acid dissolved in the solvent, the other a lean fraction comprising the residual oil and removing the solvent from the first phase. The oils are safflower seed, sunflower seed, maize and cottonseed oils. The solvent comprises dimethyl formamide or N methyl pyrrolidone with a small amount of (1) water or ethylene glycol and (11) light petroleum present.
