| titleOfInvention | A kind of post-treating method of oxalate hydrogenation liquid |
| abstract | The invention discloses a kind of post-treating method of oxalate hydrogenation liquid, the method, by passing into ammonia in the reaction solution after barkite hydrogenation, makes the intermediate product ethyl glycolate amination of unreacted barkite or partial hydrogenation in reaction solution generate oxamide and 2-hydroxyl acetamide.Then be separated by simple press filtration and oxamide and 2-hydroxyl acetamide are separated and collected, the method not only reduces follow-up rectifying cost, decreases the wasting of resources, can contribute to the ethylene glycol product obtaining high-quality simultaneously. |
