| Abstract: | Toluene was nitrated regioselectively under Menke conditions by concentrated nitric acid in the presence of modified Kaolinites as solid acid catalyst. Para selectivity was much improved, up to a paratoortho ratio of 1.3(as compared with the ratio 0.6 when nitrated by sulfonitric acid) in the mononitration products of toluene. |
