Abstract

Un método para fabricar un catalizador de paladio-oro impregnado fijando por separado el paladio y el oro, y reduciendo los solidos fijos a metales libressobre una base util para la fabricacion de acetato de vinilo a partir de etileno y ácidoacético . Particularmente, se incluye la formacion de un catalizadorpor 1) impregnacion no sucesiva de un soporte con una solucion acuosa de sales de Pd y Au, 2) la fijacion no sucesiva de cada uno de los metales preciosossobre el soporte, 3) ellavado con a gua para remover los iones formados, y 4) la reduccion de hidroxidos metálicos formados a metales Pd y Au libres.
