Abstract
The kinetics of oxidation of N-methylaniline by periodate in
acetone-water medium has been studied. The order with respect to
both oxidant and substrate has been found to be one in each case.
The rate increases on increasing ionic strength while it decreases
with a decrease in dielectric constant. The rate-pH profile has been
given and discussed. There is no effect of free radical scavengers
on rate of reaction. The thermodynamic parameters are also
presented and discussed. The main product of oxidation confirmed
by IR spectrum and melting point was p-benzoquinone. A suitable
mechanism has been proposed and the rate law derived.
