| titleOfInvention | Method for producing acetic acid |
| abstract | The invention provides a method for industrially producing acetic acid with a good potassium permanganate test value without consuming huge costs.n n n The method for producing acetic acid of the present invention includes a carbonylation reaction step, an evaporation step, a low boiler removal step, and an aqueous phase and/or an organic phase that condenses the first top distillate stream obtained in the low boiler removal step At least a part is recycled to the first top distillate stream recycling step of the reaction tank. The acetic acid manufacturing method is characterized by controlling the concentration of crotonaldehyde in the first acetic acid stream obtained in the step of removing low boilers to 2.2 mass ppm the following. The catalyst system may further include ionic iodide. In addition, the method for producing acetic acid may further include a step of separating and removing acetaldehyde. The step of separating and removing acetaldehyde is used to distill at least a part of the aqueous phase and/or organic phase obtained by condensing the first top distillate stream to remove The acetaldehyde is separated and removed. |
