A novel low toxicity caprolactam-cation-based Bronsted acid ionic liquid(IL) was prepared and used as the solvent and catalyst in the nitration of toluene with 1 equiv of 67% nitric acid. The structure of the ionic liquid was characterized by ¹H NMR and FTIR. The effect of reaction temperature, reaction time and the amount of catalyst on product yield and para-selectivity for the nitration of toluene was investigated. Nitroto-luene with a yield of 37.1% and an ortho-para isomer ratio of 1.2 was obtained under the optimal conditions. The ionic liquid was recycled 4 times with a slightly decreased yield and the same para-selectivity. The structure of the reused ionic liquid was characterized by MS, and it was found that the IL was stable under the reaction conditions.
