| titleOfInvention | A kind of preparation method of 1,2-cyclopentadicarboximide |
| abstract | The invention relates to an organic synthesis method, in particular to a preparation method of 1,2-cyclopentadicarboximide. The method uses 1,2-cyclopentadicarboxylic acid as a catalyst to cyclize 1,2-cyclopentadicarboxamide to prepare 1,2-cyclopentadicarboximide. Then add an appropriate amount of depolymerization agent to the above reaction solution to depolymerize part of the by-products into the target product, and evaporate it under reduced pressure to obtain crude 1,2-cyclopentadicarboximide. Finally, it is refined and reshaped by an organic solvent to obtain the finished product of 1,2-cyclopentadicarboximide. The invention not only simplifies the process path, improves the reaction conditions, improves the product quality and yield, but also eliminates a large amount of waste salt pollution in the original process, and the ammonia gas produced at the same time can be recycled, providing a green and feasible industrial production. route. |
