Abstract

Soporte de catalizador para la producción de acetato de vinilo monómero que, sobre un soporte de dióxido de silicio, aluminosilicato u óxido de aluminio, contiene como componentes catalíticamente activos paladio, oro y acetato alcalino, el cual se puede obtener por impregnación del soporte con una solución de carácter básico, una solución que contiene sales de oro y paladio, teniendo lugar la impregnación simultánea o sucesivamente, con o sin secado intermedio, lavado del soporte para separar las porciones de cloruro eventualmente presentes, y reducción de los compuestos insolubles precipitados sobre el soporte antes o después del lavado, secado de la etapa previa de catalizador, así obtenida, e impregnación con acetatos alcalinos o compuestos alcalinos, los cuales, bajo las condiciones de reacción en la producción de acetato de vinilo monómero, se transforman completa o parcialmente en acetatos alcalinos, caracterizado porque la reducción en el gas de conformación (95 % en volumen de N2 +5 % en volumen de H2) se lleva a cabo a temperaturas entre 300 y 550, preferentemente entre 350 y 500°C.
