Catalyzed Nitration Of Aromatic Compounds with Nano Clay/IL

The unique nitration of the Aromatic Compounds was examined on one types of Iranian clay (Salafchegan) under the nonpolare solvent conditions using cyclohexane. For this propose, Clay was modified in some steps. Then IL (1-Butyl-3-methylimidazolium chloride ) wa immobilized on Clay surface. Our solid catalyst whit 4 different weight percents (1,5,10,15 wt%) characterized by FT-IR, XRD, SEM, TEM. Nitration by this catalyst (nano-caly/IL) had good conversion of starting materials and excellent slectivity Reaction conditions were optimized for Nitration by varying temperature, amount of catalysis, time. 99% conversion of Phenol with 94% selectivity (p-nitrophenol) were obtained. The reaction did proceed in the absence of catalysis by 67% conversion and 57% selectivity (p-nitrophenol) and 43% (o-nitrophenol) and negligible dinitrophenol.
