| titleOfInvention | Process for producing acetic acid |
| abstract | The present invention relates to a method for producing acetic acid while suppressing an increase in the concentration of hydrogen iodide and acetic acid in an acetaldehyde distillation column. The present invention also provides a method for producing a volatile component (2A) comprising the steps of reacting methanol and carbon monoxide, supplying the reaction mixture to a flasher to separate the volatile component (2A) and the low-volatile component (2B) , An overhead (3A) containing methyl iodide, acetic acid, methyl acetate, water, acetaldehyde and hydrogen iodide and an oil (3B) containing acetic acid and recovering acetic acid, 3A) is supplied to an acetaldehyde distillation column and a separation step of separating the liquid to be treated containing the overhead (3A) into a low boiling point component (4A) containing acetaldehyde and a high boiling point component (4B) In the separation step, distillation of the to-be-treated liquid containing methanol and / or dimethyl ether at a concentration of 0.1 to 50% by weight is carried out. |
