Abstract

A process for purifying a fatty acid containing unwanted unsaponifiable materials involving: (a) providing a C4-C26 fatty acid starting material containing unsaponifiable materials; (b) reacting the fatty acid starting material with a zinc oxide component to form a zinc soap; (c) heating the zinc soap; (d) distilling the unsaponifiable materials from the zinc soap; (e) cooling the purified zinc soap; (f) adding a neutralizing acid component to the purified zinc soap to form a mixture containing a zinc salt and an organic layer containing clean fatty acid; and (g) distilling the purified fatty acid from the organic layer.
