Abstract
Un proceso para la producción selectiva de acetato de etilo mediante la reacción de ácido acético en fase de vapor sobre una composición catalizadora de hidrógeno para formar acetato de etilo. En una realización, la reacción de ácido acético e hidrógeno sobre platino y cobre soportados en sílice produce selectivamente acetato de etilo en una fase de vapor a una temperatura de aproximadamente 250sC. Reivindicación 1: Un proceso para formación selectiva y directa de acetato de etilo a partir de ácido acético, caracterizado porque comprende: poner en contacto una corriente de carga que contiene ácido acético e hidrógeno a una temperatura elevada con un catalizador de hidrogenación adecuado que contiene por lo menos un metal seleccionado del grupo que consiste de níquel, platino y paladio y por lo menos un metal seleccionado de molibdeno, renio, zirconio, cobre y cobalto soportado sobre un soporte de catalizador adecuado con la condición que se puede utilizar platino sin molibdeno, renio, zirconio, cobre o cobalto, y porque el catalizador incluye adicional y opcionalmente uno o más catalizadores de metal adicionales seleccionados del grupo que consiste de rutenio, iridio, cromo, estano, tungsteno, vanadio y zinc. Reivindicación 23: Un proceso para formación selectiva y directa de acetato de etilo a partir de ácido acético, caracterizado porque comprende: poner en contacto una corriente de carga que contiene ácido acético e hidrógeno a una temperatura elevada con un catalizador de hidrogenación adecuado que contiene 0,5 por ciento en peso a 1 por ciento en peso de platino o paladio y 2,5 por ciento en peso a 5 por ciento en peso de cobre o cobalto sobre un soporte de catalizador adecuado.
