【摘要】 研究了2,4-二硝基苯胺在不同条件下的硝化情况。当以乙酰硝酸酯作硝化剂、浓硫酸作溶剂时,2,4-二硝基苯胺硝化得到的主要产物是N,2,4,6-四硝基苯胺;而以乙酰硝酸酯作硝化剂、冰醋酸作溶剂时,主要产物是N,2,4-三硝基苯胺。通过IR1、HNMR、质谱、元素分析对产物进行了表征,同时研究了反应温度对产率的影响。更多还原

【Abstract】 The N-nitration of 2,4-dinitroaniline was investigated.When it was treated with acetyl nitrate in concentrated sulfuric acid and glacial acetic acid respectively,N,2,4,6-tetranitroaniline and N,2,4-trinitroaniline were produced accordingly.The influence of temperature on the products was also studied.Their structures were confirmed by IR,1HNMR,MS and elemental analyses.更多还原
