Abstract:
A method for carbonylating an aromatic hydroxy compound, said method comprising the step of contacting at least one aromatic hydroxy compound with oxygen and carbon monoxide in the presence of a carbonylation catalyst composition comprising the following and any reaction products thereof:an effective amount of at least one Group 8, 9, or 10 metal source; an effective amount of at least one inorganic co-catalyst comprising a Group 14 element source; and an effective amount of at least one salt co-catalyst with an anion selected from the group consisting of carboxylate, benzoate, acetate, sulfate, nitrate, arylborate, alkylsulfonate, arylsulfonate, and cyanide; wherein the carbonylation catalyst composition is free of a halide source to afford aromatic carbonates.
