The kinetics of oxidation of Schiff’s bases by TCICA in 100./. methanol has been investigated.The fractional order dependence of rate on [substrate] was confirmed by MIchaelis-Menton plot.The order with respect to acid is also found to be fractional. The activation parameters for variously substituted Schiff’s bases have been calculated by carrying out the reaction at various temperatures. A suitable mechanism has been proposed.
