Abstract
Procesos para reducir y/o eliminar los compuestos reductores de permanganato (PRC, por sus iniciales en inglés) que se forman con la carbonilación del metanol en presencia de un catalizador de la carbonilación de metales del grupo VIII para producir ácido acético. Más particularmente, procesos para reducir y/o eliminar los PRC o sus precursores de las corrientes intermediarias durante la formación de ácido acético en dichos procesos de carbonilación. En particular, procesos en los cuales se somete a destilación a una corriente de vapor de cabeza con bajo punto de ebullición proveniente de una columna de fracciones volátiles para obtener una cabeza que se somete a una extracción con el fin de eliminar y/o reducir selectivamente los PRC del proceso. Los procesos incluyen los pasos de reciclar una o más corrientes de retorno derivadas del paso de destilación y/o del paso de extracción hacia una columna de fracciones livianas y/o una columna de secado con el fin de mejorar el control del agua en el sistema de reacción general.Reivindicación 1: Un proceso para eliminar compuestos reductores de permanganato (PRC, por sus iniciales en inglés) de una composición en bruto que comprende ácido acético y uno o más PRC, donde el proceso comprende los pasos de: (a) separar la composición en bruto que contiene ácido acético en una columna de fracciones volátiles para dar una corriente enriquecida en PRC y una corriente de ácido acético; (b) separar la corriente enriquecida en PRC para obtener una fase acuosa y una fase orgánica; (c) separar la fase acuosa en una columna de destilación para dar una corriente de cabeza y una corriente del fondo; y (d) dirigir hacia la columna de fracciones volátiles a una primera corriente de retorno que comprende una porción de alícuota de la corriente del fondo.
