摘要
本文介绍了以单乙醇胺、硫酸、碱等原料制备氮丙环的方法。讨论了原料配比、反应时间、温度等对产率的影响,从而确定了合理的合成工艺条件。
The method of preparing ethylenimine with monoethanolamine （MEA）, sulphuric acid and alkali is introduced in the paper. The influences of prooportion of raw meterial, reaction time and reaction temperature on the efficiency are discussed. In this case the technical condition was determined for the systhesis.
