Claim Text:
1. Carbonylation process for the production of esters, carboxylic acids or combinations of two or more of the foregoing comprising combining in a reaction zone at least one carbonylation feedstock compound selected from alkanols, dialkyl ethers, and combination of any two or more thereof with carbon monoxide in a carbonylation zone of a carbonylation reactor in the presence of a catalyst material, wherein the catalyst material comprises the contact product of: (a) a monomeric nitrogen-containing compound selected from pyridines and imidazoles; (b) a Group VIII metal; and (c) an alkali metal compound; wherein the catalyst material is on a solid support; and wherein said monomeric nitrogen-containing compound is selected from compounds having the structure of Formulas I and II: wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 are independently selected from hydrogen, substituted or unsubstituted, linear or branched-chained C 1 -C 20 alkyl, substituted or unsubstituted cyclic C 3 -C 20 alkyl, and substituted or unsubstituted C 6 -C 20 aryl.
