ABSTRACT:
A method for refining of soaps, in which method the unsaponifiable neutral substances included in the soap are separated by means of extraction from an aqueous solution containing low molecular weight ketones by water immiscible organic solvents, whereby an organic phase is obtained that contains unsaponifiable neutral substances, and a water phase that contains mainly salts of fatty acids and rosin acids, which phases are separated and processed in a way in itself known, whereby neutral substances and, correspondingly, a crude oil with a high content of free fatty and other acids and, consequently with a high acid number, are obtained.
