| titleOfInvention | Method for producing acetic acid |
| abstract | The invention provides a method for industrially efficiently producing acetic acid with good test value of potassium permanganate without consuming huge cost.n n n The method includes the step of distilling the water phase and / or the organic phase of the condensate at the top of the low-boiling column in the decrotonaldehyde column, so that the reflux ratio of the low-boiling column is 2 or more (when the water phase is refluxed) And operate the crotonaldehyde tower in a manner that satisfies at least one of the following conditions (i) to (iii).n n n (i) Make the reflux ratio of this distillation column 0.01 or moren n n (ii) The ratio (the former / the latter) of the crotonaldehyde concentration (mass ppm) in the distillate of the distillation column to the crotonaldehyde concentration (mass ppm) in the addition liquid is less than 1n n n (iii) The ratio (the former / the latter) of the crotonaldehyde concentration (mass ppm) in the effluent from the bottom of the distillation column to the crotonaldehyde concentration (mass ppm) in the addition liquid is greater than 1 |
