Paragraph 0021, (2016/11/21)
The invention discloses a synthesis method for increasing the yield of N-(2,4,6-trichlorophenyl)maleimide. The synthesis method comprises the steps that firstly, an N-(2,4,6-trichlorophenyl)maleimide intermediate product is synthesized at the room temperature, and then the intermediate product is catalyzed and dehydrated to obtain N-(2,4,6-trichlorophenyl)maleimide. According to the synthesis method, the reaction temperature is low, the industrial cost is low, little harm is caused, and the yield can reach 95%.
