ABSTRACT:
A process for purifying lysocellin which comprises mixing lysocellin solids with sufficient halogen acid to convert fatty acid ester salt impurities into water-soluble metal halogen salts and water-insoluble free fatty acids and to convert lysocellin salts into water-soluble metal halogen salts and water-insoluble lysocellin acid, separating the halogen salts from the lysocellin acid and fatty acid solids, mixing the lysocellin acid and fatty acid solids with sufficient caustic reagent to convert free fatty acids into water-soluble alkali metal salts and to convert lysocellin acid into a water-insoluble alkali metal lysocellin salts, and separating the water-soluble fatty acid alkali metal salts from the alkali metal lysocellin solids.
