| titleOfInvention | Processing system of xylol oxidation reaction liquid |
| abstract | The utility model relates to a fine chemistry industry technical field, in particular to processing system of xylol oxidation reaction liquid, include: the system comprises: a light component removal system (A) which is provided with a first light component removal unit (011), an oxidation reaction liquid (a1) inlet, a light component (a2) outlet and a light component removal mother liquid (a3) outlet; a de-weighting system (B) having a first rectification device (021), an inlet for high boiling point solvent (c1), an inlet for light weight removal mother liquor (a3), an outlet for benzoic acid (B1), an outlet for methylbenzoic acid (B2), and an outlet for heavy components (B3), wherein the inlet for high boiling point solvent (c1) introduces high boiling point solvent (c1) into the de-weighting system (B). The utility model discloses the method not only can reduce the product loss to oxidation reaction liquid treatment in-process, but also can reduce the content of single impurity benzoic acid, improves methyl benzoic acid's purity. |
