ABSTRACT:
This invention concerns process for the regeneration of carbonylation catalysts consisting of dispersions of ligand-stabilized palladium(II) halide complexes in quaternary ammonium, phosphonium and arsonium salts of trihalostannate(II) and trihalogermanate(II). The regeneration agents are those which are generically classified as oxychlorinating agents.
