CARBONYLATION CATALYST AND PROCESS USING SAME

摘要

Carbonylation catalysts and methods for using them are disclosed. In some embodiments, the carbonylation catalyst includes the contact product of:
(a) a nitrogen compound selected from monomeric pyridines and imidazoles;(b) a Group VIII metal; and(c) an alkali metal compound;wherein the catalyst material is on a solid support.

主权项

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.
