Kinetic studies of the effect of organic sulphides on the oxidation of other sulphides /

Abstract

The rates of oxidation of three Organic sulphides viz. methyl phenyl sulphide, (P), p -me thoxyphenyl methyl sulphide (M) and methyl p-nitrophenyl sulphide (N). have been obtained in ethanol using MoO-(acac)- as catalyst and Bu OOH as the oxidizing agent. A Hammett plot gave a rho value of -2.1 and the activation energies for the oxidation of P, M and N were estimated to be 63.60, 40.12 and 197.46 Kj mol respectively. The effect of organic sulphide on the oxidation of another sulphide was also ascertained. Positive and negative deviations were observed from the expected slope.
