Abstract

Un catalizador bimetálico heterogéneo de paladio-oro para la produccion de acetato vinílico a partir de etileno, ácido acético y oxígeno. Un catalizadorde la presente invencion está preparado mediante la formacion de un primer revestimiento dedispersion en capa de metal de paladio coloidal sobre lasuperficie de soporte del catalizador y superponiendo un segundo revestimiento de dispersion en capa de metal de oro coloidal sobre la superficie de soportedel catalizador. Un compuestoorganom etálico de oro se emplea para aplicar la dispersion de oro sobre la superficie de soporte del catalizador. El compuestoorganométrico de oro no requiere un procedimiento de fijacion, que normalmente es la causa de una escasa retencion demetal de o ro. Un catalizador preferido de paladio-oro tiene una elevada retencion de metal de oro y exhibe durabilidad y selectividad a largo plazo en la produccion de acetato vínilico.
