ABSTRACT:
A carbonylation catalyst useful for the carbonylation of methanol to acetic acid, acetic anhydride or both comprises a polymer support containing pendant pyrrolidone groups which support a rhodium species. Other polymeric supports capable of withstanding carbonylation temperatures of at least 150.degree. C. are disclosed for the carbonylation reaction in which rhodium levels in the reaction medium of greater than 500 ppm are contemplated.
