| titleOfInvention | A kind of reclaim the method remaining cis-butenedioic anhydride in cis-butenedioic anhydride reaction unit |
| abstract | The present invention relates to a kind of method reclaiming and remaining cis-butenedioic anhydride in cis-butenedioic anhydride reaction unit, comprise the following steps: 1) organic absorbent is injected in absorption tower from absorbing tower top spray, and cis-butenedioic anhydride is absorbed；2) adsorbent solution is entered in absorption tower in the middle part of absorption tower, and cis-butenedioic anhydride is carried out double absorption；3) in absorbing tower, it is passed through acid solution, and residuals remaining in absorption tower is carried out；4) will be through step 1) reacted residue organic absorbent reclaims, will be through step 2) reacted residue organic absorbent reclaims, and in mixed solution, add catalyst, and after mixture washing, filtering, by mixture crystallisation by cooling and filter, in filtrate, again add catalyst, and will be after mixture washes, filters, by mixture crystallisation by cooling and filter, and after twice crystallization is mixed and be dried；The cis-butenedioic anhydride of residual in reaction unit can be reclaimed by the present invention, effectively achieves the recycling realizing resource. |
