Abstract
Un procedimiento de producción de ácido acético de conformidad con la presente 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 del 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.An acetic acid production process according to the present invention inhibits the concentration of hydrogen iodide and improves a liquid-liquid separation of a fixed charge from a distillation column; Acetic acid is produced by distilling a mixture containing hydrogen iodide, water, acetic acid and methyl acetate in a first distillation column (3) to form a fixed charge and a side cutting current or a bottom stream containing acid acetic, cooling and condensing the fixed charge in a condenser (C3) to form separate upper and lower phases in a decanter (4); In accordance with this procedure, an area having a high concentration of water is formed in the distillation column above the feed position of the mixture by feeding a mixture having a water concentration of not less than an effective amount of no more 5% by weight (for example, 0.5 to 4.5% by weight) and a methyl acetate concentration of 0.5 to 9% by weight (for example, 0.5 to 8% by weight) as the mixture to the column of distillation and distilling the mixture; In the area that has a high concentration of water, hydrogen iodide is allowed to react with methyl acetate to produce methyl iodide and acetic acid.
