Processes for regenerating dispersions of ligand stabilized, palladium and platinum (II) halide-complexes used in carbonylation and hydroformylation catalysts

摘要

This invention concerns using mineral acid treatment for the regeneration of carbonylation and hydroformylation catalysts consisting of dispersions of ligand-stabilized palladium(II) and platinum(II) halide complexes in quaternary ammonium, phosphonium and arsonium salts of trihalostannate(II) and trihalogermanate(II).
