| titleOfInvention | Method for producing carboxylic acid |
| abstract | The present invention provides a carboxylic acid stream containing a carboxylic acid having a carbon number of n + 1, a hydrogen halide, a low boiling point (bp) component, a high boiling point component and the like to a first distillation column; Separating the low boiling point fraction containing a part of the low boiling point component and the high boiling point fraction containing a part of the high boiling point component in the first distillation column; Side flow containing at least carboxylic acid is taken out of the first column by side cut; Feeding the side stream to the second distillation column; Separating the low boiling point fraction containing a part of the low boiling point component and the high boiling point fraction containing a part of the high boiling point component into the second distillation column; Side flow containing the carboxylic acid is taken out by the side cut to recover the purified carboxylic acid; Purified car further comprising supplying water to the first distillation column with at least one first component (A) selected from the group consisting of alcohols having n carbons corresponding to carboxylic acids and esters of alcohols and carboxylic acids, and if necessary It relates to a process for producing an acid. This method reduces the hydrogen halide concentration in the purified carboxylic acid. |
