Abstract

Un procedimiento de producción de ácido acético de conformidad con la presente invención inhibe la concentración de yoduro de hidrógeno y mejora una separación líquido-líquido de una carga fija de una columna de destilación; el ácido acético se produce destilando una mezcla que contiene yoduro de hidrógeno, agua, ácido acético y acetato de metilo en una primera columna de destilación (3) para formar una carga fija y una corriente de corte lateral o una corriente de fondo que contiene ácido acético, enfriando y condensando la carga fija en un condensador (C3) para formar fases separadas superior e inferior en un decantador (4); de conformidad con este procedimiento, una zona que tiene una alta concentración de agua se forma en la columna de destilación arriba de la posición de alimentación de la mezcla alimentando una mezcla que tiene una concentración de agua de no menos que una cantidad efectiva de no más de 5% en peso (por ejemplo, de 0.5 a 4.5% en peso) y una concentración de acetato de metilo de 0.5 a 9% en peso (por ejemplo, de 0.5 a 8% en peso) como la mezcla a la columna de destilación y destilando la mezcla; en la zona que tiene una alta concentración de agua, se le permite al yoduro de hidrógeno reaccionar con acetato de metilo para producir yoduro de metilo y ácido acético.
