| titleOfInvention | Method for producing acetic acid |
| abstract | The invention provides a method for efficiently manufacturing acetic acid with good test value of potassium permanganate without costly cost.n n n The method for producing acetic acid of the present invention includes a carbonylation reaction step, a separation step, a circulation step, a liquid separation step, and an acetaldehyde separation and removal step. The acetaldehyde separation and removal step is based on the liquid temperature at the time of liquid separation in the liquid separation step. The acetaldehyde concentration of the aqueous phase and/or organic phase, the distribution ratio of acetaldehyde, the concentration of methyl acetate or the distribution ratio of methyl acetate in the aqueous phase and/or organic phase are selected from at least a part of the aqueous phase and/or organic phase The object to be processed is processed, and in this separation step, the crotonaldehyde concentration in the first acetic acid stream is controlled to 2.2 mass ppm or less, and the crotonaldehyde concentration C CR (mass ppm) and 2-B in the first acetic acid stream are adjusted The ratio of crotonaldehyde concentration C ECR (mass ppm) (C CR /C ECR ). |
