Abstract

UN METODO DE PREPARAR UN CATALIZADOR, PARTICULARMENTE UTIL EN LA REACCION DE ETILENO, OXIGENO Y ACIDO ACETICO, EN LA FASE DE VAPOR, PARA FORMAR ACETATO DE VINILO, COMPRENDE LA IMPREGNACION DE UN SOPORTE POROSO CON SALES DE PALADIO Y ORO, SOLUBLES EN AGUA, FIJANDO EL PALADIO Y EL ORO SOBRE EL SOPORTE COMO COMPUESTOS INSOLUBLES EN AGUA, MEDIANTE LA INMERSION DEL SOPORTE IMPREGNADO EN UNA SOLUCION DE REACCION, Y DEPOSITANDO EL SOPORTE IMPREGNADO EN LA SOLUCION DE REACCION DURANTE, AL MENOS, 1/2 HORA, PARA COMENZAR LA PRECIPITACION DE LOS COMPUESTOS INSOLUBLES, Y COMPLETAR LA PRECIPITACION DE LOS COMPUESTOS INSOLUBLES SOBRE EL SOPORTE, Y REDUCIR LOS COMPUESTOS INSOLUBLES PARA LIBERAR EL PALADIO Y EL ORO. EL CATALIZADOR PREPARADO DE ESTA FORMA SE HA COMPROBADO QUE PROPORCIONA PERFECCIONAMIENTOS CON RESPECTO A LA SELECTIVIDAD REDUCIDA AL CO2 DURANTE LA REACCION DE FORMACION DE ACETATO DE VINILO.
