Beschreibung
Zusammenfassung:	A process for purification of wool grease comprising mixing the grease miscelle in a hydrocarbon solvent with an alcohol in a ratio of from 10:1 to 10:4, mixing an aqueous solution of an alkali with an alcohol in a ratio of water:alkali-alcohol of 60-75:2-5:20-35, neutralization of free fatty acids by dispersing said mixture of the grease miscelle with the alcohol in said aqueo-alcoholic solution, followed by separation of the formed phases by settling.
