ABSTRACT:

The kinetics of oxidation of mandelic, lactic, glycolic acids by quinolinium chlorochromate has been studied in aqueous medium. The reaction order is one with respect to oxidant, fractional with respect to substrate and one with respect to Hydrogen ion concentration. Decrease in the dielectric constant of the medium reduces the rate of the reaction. Increase in the ionic strength has no effect on the reaction rate. The reaction does not induce the polymerization of aerylonitrile. From the kinetic data obtained, the activation parameters have been calculated and a plausible mechanism has been proposed. An attempt to compare the reactivity of these acids was also made. .
