| titleOfInvention | process to produce acetic acid |
| abstract | process for producing acetic acid acetic acid is produced, while inhibiting the increase in the concentrations of hydrogen iodide and acetic acid in an acetaldehyde distillation column. a process for producing acetic acid comprises a step to allow methanol to react with carbon monoxide; a step for feeding a vaporizer with a reaction mixture, to separate a volatile component (2a) and a low volatility component (2b); a step to feed a distillation column with the volatile component (2a), and separate a supernatant (3a) containing methyl iodide, acetic acid, methyl acetate, water, acetaldehyde, and hydrogen iodide, and a stream (3b) containing acetic acid to collect acetic acid; and a separation step to feed an acetaldehyde distillation column with at least part of the supernatant (3a), and separate a liquid object to be treated containing the supernatant (3a) and a lower boiling component (4a) containing acetaldehyde and a component with a higher boiling point (4b); on what; in the separation step, the liquid object containing methanol and / or dimethyl ether, in a concentration of 0.1 to 50% by weight, is subjected to distillation. |
