Vapor phase carbonylation
Abstract
Abstract A GAS PHASE CARBONYLATION REACTION IS PROVIDED WHEREIN A GAS MIXTURE OF A LOW MOLECULAR WEIGHT OLEFIN, CARBON MONOXIDE, AND A COREACTANT SUCH AS AN ALCOHOL, AMINE, WATER OR HYDROGEN IS CONTACTED IN THE VAPOR PHASE WITH A HETEROGENEOUS CATALYST COMPRISING A GROUP VIII METAL AND A BIPHYLLIC LIGAND WHICH IS SUPPORTED IN THE REACTION ZONE ON A SUITABLE INERT SOLID SUPPORT SUCH AS SILICA OR ALUMINA. IN A TYPICAL APPLICATION, PROPYLENE IS HYDROFORMYLATED TO BUTYRALDEHYDE BY THE CONTACTING OF A GAS MIXTURE OF PROPYLENE, CARBON MONOXIDE AND HYDROGEN WITH A TRIS (TRIPHENYLPHOSPHINE) RHODIUMHYDRIDECARBONYL CATALYST IMPREGNATED ON SILICA PELLETS. THE REACTION IS PERFORMED AT 400 P.S.I.G. AND ABOUT 280*F. TO PRODUCE AN EXCELLENT YIELD OF BUTYRALDEHYDE HAVING A HIGH NORMAL TO ISO RATIO.
