Abstract
Unsaponifiable material is extracted from saponified synthetic fatty acids by treatment with a chlorinated hydrocarbon. The treatment is performed above about 70.degree. C at a pressure sufficient to ensure the hydrocarbon does not boil. The reactants settle into two layers without emulsification with the unsaponifiables contained in the lower chlorinated hydrocarbon layer.
