In the first part contours of the second order rate
constant (k2) for homogeneous aromatic nitration have been
determined over a portion of the three-component diagram (H2SO4-HNO3-H2O) using three aromatics of differing
reactivity (toluene, chlorobenzene and p-dichlorobenzene).
Activation energy measurements are also reported over the
same section of the three-component diagram. Those results
lead to the conclusion that the major factor in rate and
energy considerations is the acidity of the medium and that
some rates previously measured in heterogeneous systems are
kinetically controlled. [Continues.]
