3813. ----- [VEREINIGTE OELFABRIKEN HUBBE & FARENHOLTZ] [Production of Fatty Acids by Oxidation of Paraffin Hydrocarbons.] French Patent 837,251, Feb. 7, 1939. Chem. Abs., vol. 33, 1939, p. 6880.

Hydrocarbons are oxidized in presence of a catalyst consisting of a salt of a metal of group 6, 7, or 8 of the periodic system, together with a fatty, resinic or naphthalenic acid, and preferably together with a compound of an alkali or alkaline earth metal including Mg. Only a part of the catalyst mixture is added to the paraffins at the beginning of the oxidation, the remainder being added during the course of the reaction. The catalyst mixture may contain Mn stearate, Co resinate, or Fe naphthenate. Oxidation may be effected at 90°-150°.
