Abstract: 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.

Key words: zeolite, toluene, nitration reaction, isomer
