The homogeneous rates of nitration of ortho-, meta- and para-nitrotoluene in aqueous sulphuric acid
have been determined over a range of temperatures.
Some difficulties were experienced in measuring the
rate of nitration of ortho-nitrotoluene because of
competition between nitration of the latter and one or
more side-reactions, the exact nature of which were not
determined. Some possible explanations for this phenomenon
are discussed. Combination of the experimental
rate data with those published in the literature has
enabled predictions to be made of values for the observed
second order rate constant k2 as a function of
temperature and H2SO4–H2O composition. [Continues.]
