2,4,6-三硝基苯肼的合成

Synthesis of 2,4,6-trinitrophenylhydrazine

研究了用2,4，6-三硝基氯苯与水合肼反应合成2,4，6-三硝基苯肼的方法，产品与文献值一致，这是一个简单实用的方法。通过正交实验，对工艺条件进行优化，得到较优的工艺参数：三硝基氯苯：水合肼（摩尔比）=0．8，滴加速度0．02mL／min，反应温度8～10℃，收率达84．1％。

2,4,6-Trinitrophenylhydrazine was synthesized by picryl chloride and hydrazine hydrate. Properties of product is similar with literature. The present paper provided a simple and convenient method. The process was optimized by orthogonal experiment and a better synthetic condition was obtained. The results showed that mole ratio of picryl chloride to hydrazine hydrate was 0.8, adding velocity was 0.02 mL /rain,temperature was 8 - 10℃ ,the yield of product was 84.1%.
