[Also in Divisions C1 and C7] An unsaturated organic compound is reacted with a gas containing carbon monoxide in the presence of rhodium or a rhodium-containing compound as catalyst. Hexahydrobenzaldehyde is produced by reacting cyclohexene in a benzene solvent with a synthesis gas having a volume composition CO H 2 of 1 : 1 under elevated temperature and pressure in the presence of a rhodium oxide hydrate. Similar processes are described for producing hydroquinone from acetylene.
