The kinetics of oxidations of D-glucose and D-ribose by chromium(VI) and vanadium(V) in perchloric acid medium have been studied.Each reaction was first order with respect to and .The reactions were catalysed by acid, but their dependence on acidity was complex.Sodium perchlorate accelerated the rate of reaction.The rate of oxidation of ribose was greater than that of glucose.Mechanisms for these oxidations are suggested.An attempt has also been made to correlate rate constants and activation parameters for the oxidations of different aldoses by these two oxidants.
