摘要：

Vapor phase nitration of toluene by using CuFe0.8Al1.2O4 as a catalyst was studied by varying strength of nitric acid (10-69%) as a nitrating agent. Water vapor generated during the reaction acts as a diluent for the exothermic process. Varying the reaction temperature in the range of 100-200 degrees C revealed that below 125 degrees C lower conversion of toluene to mono-nitro toluene was obtained while above 125 degrees C dinitro and oxidation byproducts were obtained. The maximum conversion of toluene to mono nitro toluene was 58% with 77% selectivity towards para nitro toluene. (c) 2006 Published by Elsevier B.V.
