1424008 Rhodium carbonyl complexes UNION CARBIDE CORP 20 Dec 1972 [21 Dec 1971 19 Jan 1972] 36941/75 Divided out of 1424007 Heading C2C [Also in Divisions C1 and B1] A catalyst composition for the conversion of a mixture of hydrogen and oxides of carbon directly to polyhydric alcohols comprises a rhodium carbonyl complex formed at temperatures from 100‹ to 375‹ C. from a rhodiumcontaining substance in the presence of oxides of carbon and hydrogen at a pressure between 500 and 50,000 p.s.i.g. which is sufficient to produce the polyhydric alcohols. The complex may comprise rhodium in complex combination with carbon monoxide and organic ligands, and with/without hydrogen. Illustrative of organic ligands are N,N,N1,N1-tetramethylethylenediamine, 2,21-dipyridyl, 1,2-dimethoxyethane, glycolic acid, 2-hydroxypyridine, 1,10- phenanthroline, and pyrocatechol.

JPS5950651	[Title of the Invention] A converting method of carbon monoxide
JP2749090	Title: Catalytic hydrogenation of carboxylic acids and their anhydrides into alcohols and / or esters.
