1883年兰登堡(Landenberg)首先合成了所谓具有三元环的伯胺,但在同年葛勃里耳(Gabriel)从β-溴化乙基胺与氧化银共蒸馏所得乙烯亚胺,误以为乙烯胺CH_2=CHNH_2。直到1900年马克瓦尔德(Marckwald)作了对锰酸盐的稳定性试验,认为不可能是乙烯胺,而应该是乙烯亚胺。乙烯亚胺为三元环中最活泼的化合物,极易开环与醇基、胺基等亲核试剂起反应,本身又易聚合。自1935年以来,就被广泛应用于纺织工业,近年来发展 In 1883 Landenberg first synthesized a so-called primary amine with a three-membered ring, but in the same year Gabriel mistakenly assumed that ethylenimine was co-distilled with beta-bromoethylamine and silver oxide Vinyl amine CH_2 = CHNH_2. It was not until 1900 that Marckwald made a stability test of manganate that it could not be vinylamine but rather ethyleneimine. Ethyleneimine is the most active compound in the three-membered ring, which is easy to ring-open and react with nucleophiles such as alcohol, amine and others, and polymerizes itself easily. Since 1935, it has been widely used in textile industry and developed in recent years
