This invention relates in part to a processes for the conversion of a feedstock stream comprising carbon monoxide and hydrogen to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof. This invention also relates in part to processes for converting an alcohol and/or ether feedstock to oxygenated products, e.g., esters, acids, acid anhydrides and mixtures thereof. The processes and catalysts are especially suitable for the production of acetic acid and methyl acetate from a synthesis gas feedstock or from an alcohol and/or ether feedstock.

Processes for preparing oxygenates

This invention relates to a process for the separation of a metal complex catalyst and any free ligand which may be present, from a homogeneous organic synthesis reaction mixture using sub-nanoporous, chemically stable membranes having discrete pores which allow organic products and by-products to pass through the membrane as permeate while retaining substantially all of the metal complex catalyst and free ligand, if any, as retentate.
