ABSTRACT:
This invention provides a novel hydroformylation catalyst which is an ionic combination of a quaternary ammonium component and a ligand stabilized complex of platinum dihalide and stannous halide.
A preferred species of the invention hydroformylation catalyst can be represented empirically by the chemical structure: ##STR1## wherein R and R' are organic radicals such as alkyl and aryl, and X is a halogen radical.
The present invention stabilized platinum-tin complex hydroformylation catalyst provides a faster reaction rate at lower pressures and a superior combination of a high level of olefin conversion and efficiency to aldehyde products than prior art hydroformylation catalysts.
