Conclusions A method of recovering of the fatty material from oil‐impregnated filter aids and bleaches had been tested. it was shown to give a recovery of as much as 88% of the theoretical amount in the form of soap or fatty acids. Compared to solvent extraction, the method described gives a lower yield and a less valuable product. Its main advantage is that it may be used where the use of solvents or the investment in solvent extraction equipment is objectionable. Difficulties on account of the presence of carbon, protein material, and oxidation are described, and methods of overcoming them are suggested.
