157. BECK, C., AMD WEISSBACH, H. (I. G. Farbenindustrie A. G.). [Soaps and High molecular Fatty Acids.] German Patent 695,647, Aug. 1, 1940 (Cl. 23 e-1). Chem. Abs. Vol. 35, 1941, p. 5734.

High molecular fatty acids, derived from oxidation of paraffins, are saponified in stages. Only 10-30% of the acid value in saponifying agent is added at first. The H₂O-soluble part is separate and the residue saponified in the usual way. The soaps can then be decomposed with acids.
