    Abstract: An aqueous process for the recovery of polymeric fatty acids from crystalline clay minerals including catalyst and bleaching clays is provided. The process involves contacting the clay containing the polymeric acid with a sufficient quantity of water and agitating to displace the polymeric acid, and when the displacement is essentially complete, recovering the polymeric fatty acid from the water and clay. An additional feature of this invention is the reuse of the clay for catalyst or bleaching purposes.
