  • Patent number: 10899708
    Abstract: The present invention relates to a method for purifying N-substituted maleimide. More specifically, the present invention, without performing a water washing process, enables to remove organic-acid-impurities which are difficult to remove through distillation because of having similar boiling points to the N-substituted maleimide compound by utilizing solubility of organic-acid-impurities in an organic solvent used in the preparing process of the maleimide compound, and thereby, without producing washing wastewater, ensuring removal efficiency of the organic-acid-impurities equal to or similar to an N-substituted maleimide compound subjected to a water washing process.
