3656. ----- [STÖWENER, F.] (I.G. Farbenindustrie A.G.). [Deposition of Insoluble Metal Compounds on Carriers.] German Patent 740,634, Sept. 2, 1943 (Cl. 12 g-1.01). Chem. Abs., vol. 40, 1946, p. 182.

Compounds of the desired metal are made to react with nitrogenous derivatives of CO₂ in which at least 1 of the N atoms is bound to C. Particularly suitable for this process is urea or its derivatives. The metal organic product formed in the course of this reaction should be insoluble. The reaction is carried out in the presence of the material that is to act as carrier. The whole is heated until an insoluble product is formed and then the metal urea is transformed to metal or metal oxide.
