Abstract
Olefins are hydroformylated with syngas in the presence of a novel organometallic complex catalyst to form the corresponding aldehydes at high reaction rates and improved selectively of linear aldehydes over branched aldehydes. The novel catalyst comprises an organometallic complex formed from a mixture of (1) a platinum (O) complex containing two bidentate diphosphine, diarsine or distibine ligands; and (2) A Group IVB metal halide.
Claims14
In the process of hydroformylating an olefin having from about 2 to 20 carbon atoms by reacting the olefin with hydrogen and carbon monoxide at elevated pressures in the presence of a catalyst to produce an aldehyde, the improvement of using as the catalyst a catalyst system which comprises a complex of (1) a platinum (0) complex containing two bidentate diphosphine, diarsine or distibine ligands, and (2) a Group IVB metal halide.
