169. BAUSCHINGER, C. [Utilization in the Soap Industry of Carboxylic Acids Made from Paraffin.] Fette u. Seifen, vol. 45, 1938, pp. 629-630; Chem. Abs., vol. 33, 1939, p. 9695. Synthetic fatty acids for use in the soap industry should contain the least possible amounts of hydroxy acids, lactones, lactides, keto acids, dicarboxylic acids, and unsaponifiable matter. The insufficient plasticity of soaps from synthetic fatty acids is ascribed to absence of unsaturated acids. Peculiar phenomena observed in the soap kettle in preparing soap from synthetic fatty acids are discussed briefly. BAYAN, S. See abs. 2553. |
