The invention relates to aromatic nitration reactions and, more specifically, to a process for nitrating toluene to dinitrotoluene or benzene to mono-nitrobenzene, by a liquid phase nitration reaction of anhydrous nitric acid with benzene or toluene in a reactor at a reaction temperature not exceeding 80°C in the absence of sulfuric acid to produce mononitrobenzene or dinitrotoluene in a product mixture, followed by vacuum distillation of the product mixture to remove unreacted nitric acid.
