“…The model predicts very well the experimental data within the whole range of experimentation. Hanson et al (1976) and Belson and Strachan (1989) presented values of the pseudo-first-order rate constant k\ in aqueous nitric acid solutions. The corresponding k2 values at 25 °C calculeted according to eq 11 are plotted, together with the k2 values obtained in this work, against the mole percent of nitric acid in Figure 4.…”

“…which denotes first-order kinetics with respect to both the aromatic and the nitric acid. As Belson and Strachan (1989) suggest, the rate controlling step could be reaction 2 or 3, depending on the reactivity of the aromatic compounds. When k'3 » /e'_2 (reactive aromatics, e.g.…”

The dependence of the nitration rates of toluene in an aqueous phase on reaction temperature and mixed acid composition has been examined. Ternary solutions HNO3-H2SO4-H2O with compositions normally employed in industrial applications have been used as the nitration medium. The activation energy was found to increase with an increase in either the HN03 content of the nitration medium at constant water content or the H20 content at constant HN03 content. A kinetic equation is proposed which is applicable over the whole range of conditions used.
