titleOfInvention | Method for producing acetic acid |
abstract | The invention provides a method for industrially and efficiently producing acetic acid with good potassium permanganate test value without costly cost.n n n The manufacturing method of the acetic acid includes: (1) industrially favorably separating and removing by-product acetaldehyde from the process stream, and (2) controlling the concentration of crotonaldehyde in the acetic acid stream obtained by removing the low-boiling tower below a specific value , And/or the reflux ratio of the second distillation column is controlled to be above 0.1, and (3) the step of distilling the aqueous phase and/or organic phase of the low-boiling tower overhead condensate with a crotonaldehyde tower distillation, in which the low The reflux ratio of the boiling tower is set to 2 or more (when the aqueous phase is refluxed), and the crotonaldehyde tower is operated so as to satisfy specific conditions. |
