Abstract
An aqueous acid solution is mixed with an organic water-immiscible solvent which contains saponified and unsaponified compounds, which are obtained by saponifying a wax with an alkali in the solvent, to obtain an acidified mixture having a pH of from 2.5 to 4. The mixture is allowed to separate into an aqueous phase and an organic phase, and then the aqueous phase is separated from the organic phase. An alkaline earth metal hydroxide is mixed with the organic phase to form salts of fatty acids, and in cases when an insoluble material is formed from the organic phase, the insoluble material is separated from the organic phase. Unsaponified compounds are obtained from the organic phase by evaporating the organic phase. Salts of fatty acids may be removed from the compounds.
