Abstract
N-phenylmaleimide (PMI), a compound for strengthening the heat resistance of ABS resin, is a yellow crystal. Therefore, copolymers modified with PMI exhibit color, which limits their use. In order to overcome such disadvantage, the demand for N-cyclohexylmaleimide (CHMI), which has similar properties to PMI and also is a white crystal, is increasing. However, CHMI is difficult to industrialize due to the formation of various by-products during synthesis, which requires an additional purification process resulting in a low yield. In this study, composite catalysts were developed to improve these problems and industrially produce CHMI. Finally, CHMI was synthesized with a 85% yield and at least 99.5% purity.
