Advances in hydroformylation catalysis
Hydroformylation is a key reaction in petrochemical technology for the conversion of olefins to aldehyde intermediates via reaction with synthesis gas: e.g., RCH = CH{sub 2} + CO + H{sub 2} {yields} RCH{sub 2}CH{sub 2}CHO + RCH(CH{sub 3})CHO. The reaction is catalyzed by Group VIII transition metal carbonyl hydrides, in general, but its petrochemical use is limited to cobalt and rhodium catalysts. The reaction, commonly known in the industry as the oxo-process, was discovered with cobalt in the 1940's but most of the advances were made with rhodium during the last 20 years. In the present overview, at first the significance of the reaction will be reviewed. Thereafter, basic concepts of hydroformylation catalysis will be discussed, largely on the basis of studies we carried out at Exxon. In cobalt catalysis, studies of concurrent isomerization hydroformylation will be presented. A major part of the presentation will focus on developments in rhodium hydroformylation and the steric effects of phosphine ligands on the formation of rhodium catalyst complexes of different structures under CO/H{sub 2} pressure.
