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 separating one or more cyclic products from a reaction product fluid comprising one or more cyclic reactants, a metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand, a non-polar solvent and said one or more cyclic products, wherein said process comprises: (1) reacting said one or more cyclic reactants in the presence of said metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand and non-polar solvent to form a multiphase reaction product fluid; and (2) separating said multiphase reaction product fluid to obtain a non-polar phase comprising said one or more cyclic reactants, metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand and non-polar solvent and a polar phase comprising said one or more cyclic products.

Metal-ligand complex catalyzed processes

This invention relates to the use of ion exchange resins having metal-exchanged thiol functional groups in removing iodide impurities from carboxylic acids and/or carboxylic acid anhydrides. More particularly, this invention provides a process for removing iodide impurities from liquid carboxylic acids and/or carboxylic acid anhydrides using ion exchange resins in which thiol functional groups have been exchanged with silver, palladium or mercury.

Iodide removal process

This invention relates tot he use of ion exchange resins having metal-exchanged thiol functional groups in removing iodide impurities from carboxylic acids and/or carboxylic acid anhydrides. More particularly, this invention provides a process for removing iodide impurities from liquid carboxylic acids and/or carboxylic acid anhydrides using ion exchange resins in which thiol functional groups have been exchanged with silver, palladium or mercury.
