3047. ----- [RUHRCHEMIE, A. G.]  [Process for Preparing Aluminum Soaps From Wax Acids.]  German Patent Appl. --, R 668, filed Apr. 1, 1943.  TOM Reel 36, bag 3,354,  item 36, 4 pp.; Meyer Transl. PC-S-IV, Wax Oxidation, vol. 1, chap. 18, 1948, p. 44.

In producing al soaps from wax acids, the latter are heated with addition of an organic solvent with H₂O-free Al-halogen compounds, particularly with H₂O-free AlCl₃, and the solvent evaporated after evolution of the halogen hydride has ceased.  As the solvent agent, use is made of the product of the catalytic hydrogenation of CO, in Particular a synthetic heptane fraction.  The raw material consists of wax acids that have been prepared by the oxidation with agents such as alkali bichromate or nitrous gases of paraffins, particularly those high-melting paraffins from the catalytic hydrogenation of CO and Nitroslysulfuric acid.
