醇钠滴定法合成2-氨基-4,6-二甲氧基-1,3,5-三嗪的研究

The Synthesis of 2-amino-4,6-dimethoxyl-1,3,5-triazine on Alcohol Sodium Titration

2-氨基-4,6-二甲氧基-1,3,5-三嗪是新型水稻除草剂醚磺隆的重要中间体,本文以三聚氯氰、液氨、氢氧化钠等为原料合成,平均收率为86%,含量为≥97%。并探讨了其反应机理及影响因素。

2-amino-4,6-dimethoxyl-1,3,5-triazine, an important intermediate in synthesis of the novel paddy rice herbicide cinosulfuron,was synthesized by cyanuricchloride,ammoniacal liquor, and sodium hydroxide as the raw materials,with the average yield of 86% and purity of 97%,and the reaction fundamental principle and influence factors was investigated.
