| titleOfInvention | Method for producing acetic acid |
| abstract | Provided is a method capable of industrially efficiently producing acetic acid having a good potassium permanganate test value without incurring a great deal of cost. Including a step of distilling the aqueous phase and / or organic phase of the condensed liquid at the top of the delow boiling tower in the decrotonaldehyde tower, wherein the reflux ratio of the delow boiling tower is 2 or more (when the aqueous phase is refluxed), and The decrotonaldehyde column is operated so as to satisfy at least one of the following conditions (i) to (iii). (I) The reflux ratio of the distillation column is 0.01 or more. (Ii) The ratio between the crotonaldehyde concentration (mass ppm) in the distillate of the distillation column and the crotonaldehyde concentration (mass ppm) in the charged solution. (The former / the latter) is less than 1. (iii) The ratio (the former / the latter) of the crotonaldehyde concentration (mass ppm) in the bottoms of the distillation column and the crotonaldehyde concentration (mass ppm) in the charged solution. Greater than 1 |
