Separation of fatty acids into saturated and unsaturated components.
Preliminary liquid phase extraction with Sulfolane permits the fractionation of fatty acids into saturated and unsaturated components. In a single stage operation, a fatty acid mixture of oleic and linoleic acids of 131 iodine number was separated into fractions of 142 iodine value in the extract phase and 125 iodine value in the raffinate. Hence multi-stage extraction should be of value in producing drying and non-drying fractions from soya bean oil acids and in the fractionation of the original glycerides into saturates and polyunsaturates.
