摘　　要：在实验室硝化中有多种方法可以提高甲苯一段硝化产物中对硝基甲苯（ｐＭＮＴ）的生成比例。研究认为，硝硫混酸的不同配比与硝化方式对甲苯的一段硝化产物组成有明显的影响，以浓硫酸为底酸，在一定条件下滴加硝酸对甲苯进行一段硝化，可以使产物中的对硝基甲苯的生成比例提高８％。Many methods can be used to increase pMNT yield in mononitration product of toluene in lab.It is found that the composition of mixed acid and of nitration method have considerable effect on isomer distribution of the product. With concentrated H2SO4 as substrate, toluene can be nitrated by adding diluted HNO3 at certain temperature, and the pMNT in the product increased by 8%,which is promising to be used in industry.
