2506. ------. [NATTA, G.]. [Catalysts and Their Use in Reactions in Which Carbon Monoxide Occurs.] Italian Patent 342,930, June 10, 1936. Chem. Zentralb., 1938, I, p. 431.

Catalysts are given for production of MeOH by the hydrogenation of CO and CO2 or of water gas, of ketone from organic acids containing at least 2 C atoms, of aldehydes from a mixture of HCOOH and other volatile organic acids. Catalysts are obtained by the partial or total pyrogenetic decomposition of organic salts of Zn, such as Zn acetate whose melting point is lower than its decomposition temperature, at the lowest possible temperature and increased pressure with exclusion of air and in a reducing or inert gas atmosphere.
