Summary It has been shown in the work reported previously (1,2) that it is possible to extract the oil from cotton‐seed to produce gossypol‐free meal of superior value. The miscella produced by this process contains the oil, free fatty acids, gossypol, and other non‐oil materials. Solubility and distribution data have been established for the systems isopropanol‐water‐cottonseed oil and oleic acid and isopropanol‐water‐cottonseed oil‐oleic acid‐hexane. Using these data as a basis, a liquid‐liquid extraction system has been developed which permits the separation of the miscella into a stable purified oil and a mixture of the free fatty acids, gossypol, phospholipids, sugars, and other non‐oil materials. The process is sufficiently flexible to permit the extraction of cottonseed of variable free fatty acid content and to produce a product of controlled uniformity.
