    • PURPOSE: A method for preparing N-cyclohexylmaleimide is provided to effectively control a temperature during preparation, to reduce risks, to suppress natural polymerization of CHMI(N-cyclohexylmaleimide), and to obtain a large amount of CHMI. CONSTITUTION: A method for preparing CHMI comprises: a step of dissolving maleic anhydride in an organic solvent and adding cyclohexylamine to prepare N-cyclohexylmaleimide acid; a step of mixing N-cyclohexylmaleimide acid and alcohol and preparing N-cyclohexylmaleimide acid ester; and a step of imidizing N-cyclohexylmaleimide acid ester. The organic solvent is toluene. The alcohol is isobutyl alcohol.
    • 目的:提供制备N-环己基马来酰亚胺的方法,以有效控制制备过程中的温度,降低风险,抑制CHMI(N-环己基马来酰亚胺)的天然聚合,并获得大量的CHMI。 构成:制备CHMI的方法包括:将马来酸酐溶解在有机溶剂中并加入环己胺以制备N-环己基马来酰亚胺的步骤; 将N-环己基马来酰亚胺酸和醇混合并制备N-环己基马来酰亚胺酸酯的步骤; 和N-环己基马来酰亚胺酸酯的酰亚胺化步骤。 有机溶剂是甲苯。 酒精是异丁醇。
