Abstract

Se pretende proporcionar un método de producción de ácido acético capaz de separar y eliminar industrialmente de manera ventajosa un subproducto acetaldehído en la etapa de separación para separar una corriente de proceso en fases acuosa y orgánica. En la presente, la etapa de separación satisface, por ejemplo, las siguientes condiciones (vi) a (viii), y al menos una porción de la fase acuosa se trata en la etapa de separación y eliminación de acetaldehído: (vi) las concentraciones de acetaldehído en las fases acuosa y/u orgánica no son mayores de 28.1% en masa y no mayores de 24.8% en masa, respectivamente; (vii) una temperatura de separación es no mayor a 70ºC; y (viii) las concentraciones de acetato de metilo en las fases acuosa y/u orgánica no son mayores de 12.0% en masa y no mayores de 47.6% en peso, respectivamente, y/o la suma de las concentraciones de acetato de metilo en las fases acuosa y orgánica es no mayor de 59.6% en masa.It is intended to provide a method of acetic acid production capable of industrially separating and disposing of an acetaldehyde byproduct in the separation stage to separate a process stream in aqueous and organic phases. Here, the separation stage satisfies, for example, the following conditions (vi) to (viii), and at least a portion of the aqueous phase is treated in the acetaldehyde separation and removal stage: (vi) concentrations acetaldehyde in the aqueous and / or organic phases are not greater than 28.1% by mass and not greater than 24.8% by mass, respectively; (vii) a separation temperature is not greater than 70 ° C; and (viii) the concentrations of methyl acetate in the aqueous and / or organic phases are not greater than 12.0% by mass and not greater than 47.6% by weight, respectively, and / or the sum of the concentrations of methyl acetate in The aqueous and organic phases is no more than 59.6% by mass.
