A process for preparing an aromatic N- glycidylamine comprising a step of heating a mixture of an amine having at least one aromatic aminohydrogen atom with at least 0.7 equivalent of epichlorohydrin per aminohydrogen equivalent of the amine in presence of a catalyst dissolved in an inert organic solvent, at a pressure in a range of 200 to 600 mbar; and adding a base to the mixture at a pressure in a range of 200 to 600 mbar to facilitate dehydrochlorination of product of the previous step to obtain the aromatic N- glycidylamine.
一种制备芳香族N-环氧丙基胺的过程,包括以下步骤:在惰性有机溶剂中加入催化剂,然后将至少含有一个芳香族氨基氢原子的胺与每个氨基氢当量的至少0.7当量的环氧氯丙烷混合物加热,压力范围在200到600毫巴之间;然后在压力范围在200到600毫巴之间向混合物中加入碱,以促进前一步骤产物的脱氢氯化,从而获得芳香族N-环氧丙基胺。
