| titleOfInvention | process for producing acetic acid, and method for separating or removing acetaldehyde |
| abstract | process for producing acetic acid, and method for separating or removing acetaldehyde. a method is provided to effectively remove acetaldehyde and produce acetic acid in a stable manner. methanol and carbon monoxide are reacted continuously in a carbonylation reactor (1) in the presence of a catalyst system, the reaction mixture is continuously supplied to an expander (2), and a volatile phase (2a) containing acetic acid and iodide of methyl is produced the volatile phase (2a) is continuously supplied to a separation column (3) and separated at the top (3a) containing methyl iodide and acetaldehyde, and flow fraction (3b) containing acetic acid. the volatile phase (2a) and / or the upper part (3a) are cooled by first condensers (c1, c3) having a predetermined cooling temperature, the non-condensed gas component is additionally cooled by second condensers (c2, c4) and condenses do, the temperature is further lowered, and a concentrate in which acetaldehyde was concentrated to a high concentration is produced. the high concentration acetaldehyde concentrate is distilled through a distillation column (6), and the acetaldehyde is effectively removed. |
