| titleOfInvention | Manufacturing method of N-substituted maleimide |
| abstract | The present invention relates to a method for producing N-substituted maleimide, and more specifically, to the primary reaction by adding an excess of primary amine and maleic anhydride in the presence of an organic solvent, and then acid catalyst to the primary reaction mixture And maleic anhydride in the reaction system relates to a method for producing N-substituted maleimide, characterized in that the secondary reaction by the addition of maleic anhydride so that the molar ratio of 1.0 to 1.2 with respect to the primary amine.n n n According to the present invention, it is possible to obtain N-substituted maleimide which has high yield and high purity and is not discolored and has a low production cost effect.n n n N-substituted maleimide, primary amine, maleic anhydride, acid catalyst, high yield, high purity |
