Abstract
Se pretende proporcionar un método capaz de suprimir la corrosión del aparato de destilación como un método para producir ácido acético, que comprende la etapa de destilar una solución de ácido acético crudo que comprende ácido acético y una impureza que tiene un punto de ebullición más alto que el del ácido acético para purificar el ácido acético; el método para producir ácido acético de la presente comprende la etapa descrita anteriormente, en la que la destilación de la solución de ácido acético crudo se lleva a cabo bajo una condición que implica una temperatura del fondo de la columna de destilación de no más de 165ºC; una concentración de ácido acético en la solución de ácido acético crudo a someter a la destilación es preferiblemente no menor a 90% en masa. Los ejemplos de la impureza que tiene un punto de ebullición más alto que el del ácido acético incluyen acetatos, anhídrido acético y ácido propiónico. Una presión del fondo de columna de la columna de destilación es preferiblemente menor que 0.255 MPaG.It is intended to provide a method capable of suppressing corrosion of the distillation apparatus as a method of producing acetic acid, comprising the step of distilling a solution of crude acetic acid comprising acetic acid and an impurity having a boiling point higher than that of acetic acid to purify acetic acid; The method for producing acetic acid of the present comprises the step described above, in which the distillation of the crude acetic acid solution is carried out under a condition that implies a bottom temperature of the distillation column of no more than 165 ° C ; A concentration of acetic acid in the crude acetic acid solution to be subjected to distillation is preferably not less than 90% by mass. Examples of impurity having a boiling point higher than acetic acid include acetates, acetic anhydride and propionic acid. A column bottom pressure of the distillation column is preferably less than 0.255 MPaG.
