摘 要:三聚氯氰与甲醇发生SN2亲核取代反应,得到2-甲氧基-4,6-二氯-1,3,5-三嗪。通过采用正交试验,优化缚酸剂种类、缚酸剂用量、反应温度、反应时间等反应条件,确定了合成三聚氯氰甲氧基单取代产品的优化工艺为:以NaHCO3为缚酸剂、反应温度8~10℃、反应时间5h、三聚氯氰与缚酸剂物质的量之比为1∶1,目标产物的收率为84.4%。2-Methoxy-4,6-dichloro-1,3,5-triazine was prepared from cyanuric chloride and methanol by SN2 nucleophilic substitution reaction.The synthesizing processes of the mono-substituted hydrocarbon-oxygen 1,3,5-triazine was studied by orthogonal experiment.The influencing factors of the reaction,such as acid-capturer species,reaction time,temperature and so on were investigated.The experimental results showed that the optimal reaction conditions were as follows:the acid-capturer was NaHCO3,the molar ratio of cyanuric chloride and acid-capturer was 1∶1,the reaction temperature was controlled at 8~10℃,and the reaction time was 5h.The yield reached 84.4%.
