| titleOfInvention | Method for producing acetic acid |
| abstract | The invention provides a method for industrially producing acetic acid with high efficiency.n n n In the aldehyde separation and removal step, it includes industrially advantageous separation and removal of acetaldehyde as a by-product, and the step of distilling the water phase and/or organic phase of the low-boiling tower overhead condensate in the crotonaldehyde tower to remove the acetaldehyde The reflux ratio of the low-boiling tower is stirred for 2 or more (when the aqueous phase is refluxed), and the crotonaldehyde tower is operated in a manner that satisfies at least one of the following (ai) to (a-iii).n n n (a-i) The reflux ratio of the distillation tower is set to 0.01 or moren n n (a-ii) The ratio of the crotonaldehyde concentration (mass ppm) in the distillate of the distillation column to the crotonaldehyde concentration (mass ppm) in the feed liquid (the former/the latter) is set to less than 1n n n (a-iii) The ratio of the crotonaldehyde concentration (mass ppm) in the outlet liquid of the distillation column to the crotonaldehyde concentration (mass ppm) in the feed liquid (the former/the latter) is set to be greater than 1 |
