This work has studied the effects on the nitration of toluene by 100% nitric(V) acid and a nitric(V) acid/dichloromethane mixture. The results show that the amount of meta-nitrotoluene decreases with decreases in reaction temperature. From 25 °C to –10 °C the amount of metanitrotoluene was less than for nitrating toluene by a nitric(V)acid/dichloromethane mixture than for nitration by 100% nitric(V) acid. Furthermore, from –20 °C to –30 °C results were similar with 2.6% of meta-nitrotoluene in the reaction products. An excess of nitric(V) acid in the nitration of toluene by the nitric(V) acid/dichloromethane mixture than in nitration by 100% nitric(V) acid. Nitration by the nitric(V) acid/dichloromethane mixture is less exothermic and easier to control than nitration by 100% nitric(V) acid.
