Hydroformylation catalyst and process

摘要

Olefins are hydroformylated with syngas in the presence of a novel organo metallic complex catalyst to form the corresponding aldehydes at high reaction rate and improved selectivity of linear aldehydes over branched aldehydes. The novel catalyst comprises an organo metallic complex formed from a mixture of: (1) platinum (II) acetylacetonate; (2) a Group IVB metal halide; and (3) a bidentate tertiary ligand of the formula R1R2Q(CH2)mQR3R4; or wherein Q is arsenic, antimony, or phosphorus; and R1,R2,R3 and R4 are alkyl, alkoxyl, aryl, or aryloxyl groups, and may be the same or different; and m is an integer of from 3 to about 5; and n is an integer of from 2 to about 4.
