CARBOXYLATION PROCESS FOR PREPARING LINEAR FATTY ACIDS OR ESTERS (D#74,032-1-F) ABSTRACT OF THE DISCLOSURE This invention concerns a process for preparing linear ratty (carboxylic) acids and esters from the reaction of olefins, alcohols (or water) and carbon monoxide. The process is catalyzed by catalytic amounts of dispersions of ligand-stabilized, palladium (II) halide complexes, in quaternary ammonium, phosphonium or arsonium salts of trihalostannate(II) or trihalogermanate(II). These empirically selected palladium catalysts can be re- cycled with fresh olefin feed several times before sub- stantial loss of catalytic activity is encountered. I
