A novel process for producing aziridine-2-carboxylic acid amide comprises reacting a 2,3-dichloropropionic acid ester or amide, a 2-chloroacrylic ester or amide, or mixtures thereof with ammonia, at a temperature not lower than 0°C. The process is preferably carried out in the presence of a tertiary amine or a quaternary ammonium salt. The resulting aziridine-2-carboxylic acid amide is readily purified or isolated by treating the reaction liquid with a basic anion exchange resin.
一种生产
氮丙啶-2-
羧酸酰胺的新工艺包括在不低于 0°C 的温度下,使
2,3-二氯丙酸酯或酰胺、
2-氯丙烯酸酯或酰胺或它们的混合物与
氨反应。该过程最好在叔胺或季
铵盐存在下进行。通过用碱性阴离子交换
树脂处理反应液,可以很容易地纯化或分离出所得到的
