摘要
对NaZSM-5分子筛进行改性,在其表面引入铁、镁离子,用作硝硫混酸对甲苯一段硝化反应的催化剂,明显提高产物中对硝基甲苯的生成比例,研究了影响反应结果的因素。
The Modified NaZSM-5 zeolite:Fe-ZSM-5,MgZSM-5,and Fe-Mg-ZSM-5 zeo-lites have been tested as eatalyst in mononitration of toluene by mixed acid.The para substi-tuted nitrotoluene was found to be considerably increased. Some factors affecting o/p ratiohave been investigated.
