| 摘 要： | 采用2-甲基环氧氯丙烷、尿素为原料．对合成3-氯-2-甲基-2-羟基丙基脲的方法进行了研究。最佳工艺条件为：原料体积比V（2-甲基环氧氯丙烷）／V（50％尿素水溶液）=0．58，反应温度为70～80℃，反应时间为75min，C（Na3PO4）=0．1mol／L10mL．所得产物的环氧值和氯离子生成率都比较小，产物以3-氯-2-甲基-2-羟基丙基脲为主。

| Abstract: | The method for synthesizing 3-Chloro-2-methyl2-hydroxypropylurea is investigated by the reaction of 2-methylepichlorohydrin with urea. The optimum conditions are as follows ：the volume ratio of 2-methylepichlorohydrin to 50%urea solution is 0.58, the reaction temperature is70- 80℃, the reaction time is 75minutes and 10 mL0.1mol/L Na3PO4, the chloridion production rate and epoxide number of the product are all small. The product is basically 3-Chloro-2-methyl-2- hydroxypropylurea. |
