    Abstract: Aliphatic carboxylic acid salts of metals, having a normal electrode potential of -0,80 to +0,5 volts, are prepared by reacting a pulverulent metal with the acid diluted with water or an inert organic solvent, at a temperature between room temperature and the boiling point of the acid, in the presence of free oxygen and an activator consisting of the bromide of the metal. Saturated aliphatic monocarboxylic acids, e.g. formic, acetic, propionic and butyric acids, a -ethyl hexanoic acid and unsaturated acids such as oleic are referred to, and the diluents may be g -lactones, nitriles and alkylene carbonates. Chromium, cobalt, nickel, and lead salts are prepared and copper, bismuth and iron salts are mentioned, and pure oxygen or air may be the oxidising agent. The bromides may be prepared in situ by adding metal carbonates with hydrogen bromide or tetrabromoethane, or by adding bromine to the reaction mixture. The process may be batchwise or continuous.
