Abstract

Un método para eliminar acetaldehído de una mezcla de acetato de metilo, metanol y acetaldehído incluye: (a) cargar la mezcla de acetato de metilo, metanol y acetaldehído a una columna de destilacion; (b) destilar la mezcla de alimentacion de acetato de metilo, metanol y acetaldehído a una presion de 10 psig o más para generar una corriente de vapor de sobrecarga enriquecida en acetaldehído en comparacion con la mezcla de alimentacion y una corriente de resitudo con agotamiento de acetaldehído en comparacion con la mezcla de alimentacion y (c) retirar de la columna de destilacion la corriente residual en la que el acetaldehído se ha agotado. Reivindicacion 1: Un método para eliminar acetaldehído de una mezcla de acetato de metilo, metanol y acetaldehído, que comprende: (a) alimentar la mezcla de acetato de metilo, metanol y acetaldehído a una columna de destilacion; (b) destilar la mezcla de alimentacion de acetato de metilo, metanol y acetaldehído a una presion de 10 psig o más para generar una corriente de vapor de sobrecarga enriquecida, en acetaldehído en comparacion con la mezcla de alimentacion y una corriente de residuo con agotamiento de acetaldehído en comparacion con la mezcla de alimentacion; y (c) retirar la corriente de residuo con agotamiento de acetaldehído de la columna de destilacion. Reivindicacion 24: Un proceso para la produccion de ácido acético, que comprende: (a) purificar una mezcla de acetato de metilo, metanol y acetaldehído para eliminar el acetaldehído mediante: (i) la alimentacion de la mezcla de acetato de metilo, metanol y acetaldehído a una columna de destilacion; (ii) la destilacion de la mezcla de alimentacion de acetato de metilo, metanol y acetaldehído a una presion de 10 psig o más para generar una corriente de vapor de sobrecarga enriquecida en acetaldehído en comparacion con la mezcla de alimentacion y una corriente de residuo con agotamiento del acetaldehído en comparacion con la mezcla de alimentacion; y (iii) el retiro de la corriente de residuo con agotamiento de acetaldehído de la columna de destilacion; (b) alimentar la corriente de residuo purificada a una mezcla de reaccion de carbonilacion junto con monoxido de carbono, en donde la mezcla de carbonilacion comprende agua, un catalizador seleccionado de catalizadores de rodio, catalizadores de iridio y mezclas de ellos, un promotor de yoduro de metilo y ácido acético; y (c) recuperar el ácido acético de la mezcla de carbonilacion.
