摘　　要：用乙二胺和三氧化硫脲合成了乙二胍的亚硫酸盐,产物的红外光谱具有烷基胍的特征吸收峰,能够发生烷基胍的特征显色反应,元素分析结果与目标产物吻合,残余—NH2≤0.02 mmol/g。乙醇和水的混合物是良好的反应介质,适宜的反应温度为60℃,收率为84%,研究了投料比等因素对合成反应的影响。Ethylenediguanidine salt was synthesized from aminoimino-methanesulfonic acid and ethylenediamine hydrate. The product is characterized by IR. It has characteristics color-reaction of alkyl guanidine. Result of element analysis is identical with objective product. The remnant --NH2 is ≤0.02 mmolg^- 1. Mixture of alcohol and water is a good medium. Optimum reacting temperature is 60 ℃. The product has yield of 84%. The influence of additional ratio on reaction is researched.
