1440413 Butyraldehydes (oxo process) MITSUBISHI CHEMICAL INDUSTRIES Ltd 17 Sept 1974 [21 Sept 1973] 40567/74 Heading C2C A process for producing butyraldehydes comprises reacting propylene with a water gas in a reaction solvent containing a triarylphosphine and a soluble rhodium complex in which a portion of said triarylphosphine is co-ordinated with rhodium metal, under a carbon monoxidehydrogen total pressure of from 30 to 100 kg./cm.2 and at a temperature of from 60‹ to 150‹ C., the total amount of said triarylphosphine present in said reaction solvent and in said soluble rhodium complex co-ordinated with rhodium metal being from 1 to 30 m. moles per litre of said reaction solvent. The soluble rhodium complex may be present at a concentration of from 0À1 to 500 mg., calculated as rhodium metal, per litre of said reaction solvent, and the ratio of triarylphosphine to rhodium may be 5 to 200 moles per gram-atom, and the water gas may contain 1/ 3 to 7 moles of hydrogen per mole of carbon monoxide.
