Synthesis method of n-substituted maleimide using solid acid catalysts |
| abstract |
The present invention relates to a process for producing N-substituted maleimides using heterogeneous solid acid catalysts, and more particularly, to a process for producing N-substituted maleimides by using zirconium (IV) hydrogenphosphate solid acid catalyst The catalyst can be completely regenerated through washing or firing when the activity of the separated and recovered catalyst is reduced and the selectivity of the washing solvent can be improved by minimizing the loss of the catalyst and simplifying the separation and recovery process of the catalyst, Substituted maleimides having a high yield of synthesis of N-substituted maleimides. |
