Zusammenfassung:UN CATALIZADOR DE CARBONILACION UTIL PARA LA CARBONILACION DE METANOL A ACIDO ACETICO, ANHIDRIDO ACETICO, O A AMBOS, COMPRENDE UN SOPORTE POLIMERO QUE CONTIENE GRUPOS PENDIENTES DE PIRROLIDONA QUE SOPORTAN UNAS ESPECIES DE RODIO. SE DESCRIBEN OTROS SOPORTES POLIMERICOS CAPACES DE RESISTIR LAS TEMPERATURAS DE CARBONILACION DE AL MENOS 150 ILACION EN LA QUE LOS NIVELES DE RODIO QUE ESTAN CONTEMPLADOS EN EL MEDIO DE REACCION SON MAYORES QUE 500 PPM. 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 DEG C. are disclosed for the carbonylation reaction in which rhodium levels in the reaction medium of greater than 500 ppm are contemplated.
