| titleOfInvention | METHOD FOR THE PRODUCTION OF ACETIC ACID |
| abstract | It provides a method for efficiently industrially producing acetic acid that produces a good result in the potassium permanganate test, without enormous cost; The acetic acid production method according to the present includes a carbonylation step, a separation step, a recycling step, a liquid-liquid separation step, and an object treatment acetaldehyde removal step, where The object is selected from at least a part of at least one of the aqueous phase and the organic phase based on a factor (s) selected from a temperature of the liquid in the liquid-liquid separation in the liquid separation step. liquid, a concentration of acetaldehyde in at least one of the aqueous phase and the organic phase, a partition coefficient of acetaldehyde, a concentration of methyl acetate in at least one of the aqueous phase and the organic phase, and a coefficient partitioning of methyl acetate; In the first stream of acetic acid in the separation step, a concentration of crotonaldehyde is controlled to 2.2 ppm by mass or less, and the ratio (CCR / CECR) of a concentration of crotonaldehyde CCR (ppm by mass) is regulated to a 2-ethylcrotonaldehyde CECR concentration (ppm by mass). |
