Abstract
Se proporciona un método que permite la producción industrialmente eficiente de ácido acético de alta calidad con un buen valor de prueba de permanganato de potasio y un bajo contenido de impureza sin un costo elevado; el método para producir ácido acético de acuerdo con la presente tiene un paso de reacción de carbonilación, un paso de evaporación y un paso de eliminación del componente con punto de ebullición más bajo, y en donde con calentamiento del evaporador, (i) una concentración del acetaldehído en la fase acuosa de un condensado superior en una columna de eliminación del componente con punto de ebullición más bajo se controla a no menos de 2340 ppm en masa; y/o (ii) una concentración de acetato de metilo en la fase acuosa se controla a menos de 19.0% en masa, y/o; (iii) una concentración de acetato de metilo en la fase orgánica del condensado superior en la columna de eliminación del componente con punto de ebullición más bajo se controla a menos de 38.0% en masa, y luego por lo menos una porción de la fase acuosa se trata en el paso de separación y eliminación del acetaldehído para reciclar un líquido residual después de la separación y eliminación del acetaldehído al recipiente de reacción y/o el paso de eliminación o separación del acetaldehído y/u otros procesos.
