ABSTRACT:
A process for separating an unsaponifiable compound from a feed mixture including fatty and/or rosin acids. The process comprises: (a) forming an emulsion with the feed mixture, an organic solvent in which the feed mixture is soluble and an emulsifying liquid capable of forming an emulsion with the feedstock and organic solvent, the polarity index of the emulsifying liquid being at least 2.4 higher than the polarity index of the organic solvent; (b) effecting the formation of three phases from the emulsion, an organic solvent phase containing the major portion of the fatty or rosin acids, an emulsifying liquid phase and a semi-solid sludge phase containing the major portion of the unsaponifiable compound; and (c) separating the three phases.
