摘要
报告了利用改进的Ｂｕｃｈｅｒｅｒ－Ｂｅｒｇ＇ｓ工艺进行乙内酰脲的合成方法。将自制的乙醇腈水溶液直接用于乙内酰脲的成环反应；对其过程的工艺参数进行了实验研究。所制备的乙内酰脲杂质含量低，且具有较高的收率。
篢he synthetic method for hydantoin by using improved Bucherer Berg＇s synthesis was re-ported．The self-made glycolonitrile solution was made use of hydantoin cyclized reaction. The techno-logical parameters of process were studied. The hydantoin have lower impurity and higher yield.
