3092.----- [RUHRCHEMIE, A. G.] [Process for separating Mixtures of Fatty Acids or Fatty Acid Salts and Neutral Oils.] German patent Appl. --, R 648, filed Dec. 18, 1942. FIAT Reel K-30, frames 8,024-8,027; PB 73,587; TOM Reel 36, bag 3,454, item 36, 4 pp; Meyer Transl. PC-S-IV, Wax Oxidation, vol. 1, ch. 14, 1948, p. 37.

Mixtures consisting of fatty acids or fatty-acid salts and neutral oils are separated by dissolving the fatty acids or fatty-acids salts with H₂O or a mixture of H₂O and alcohol. Before, during, or after the H₂O treatment, alkaline or acid reacting materials are added to the reaction mixture until a pH concentration of 7 is attained, whereupon neutral oils insoluble under these conditions are separated. This may take place under normal or slightly increased temperature. Mineral acids or gaseous CO₂or even fatty acids can be utilized at normal or increased pressure as the acid reacting materials.
