1761. JAHRSTORFER, M., AND SCHWARTE, G. (I. G. Farbenindustrie A. G.). [High-Molecular Waxlike Substances.] German Patent 695,860, Aug. 8, 1940; appl. 1 45,780, filed Nov. 18, 1932 (Cl. 12 6-1.01). FIAT Reel AA-90, frames 1,379-1,380: PB 70,275; Meyer Transl. PC-S-IV. Wax Oxidation. Vol. 3, chap. 47, 1949. p. 30: Chem. Abs., vol. 35, 1941, p. 5604.

High-molecular oxidation products of aliphatic hydrocarbons, fatty acids or oils, which contain a carbonyl group, are treated catalytically so as to split off CO₂, and the resulting product is hydrogenated. These substances are good for dressing and impregnating of all kinds of fiber and paper. Being neutral they also can be used for lubrication.
