A Kinetic Study Of The Oxidation Of Some Alcohols By Peroxodisulphate

Abstract

The... present-workdeais-withutheuustudy ofredox--- reaction-uf---someu alcoholic (n-propanol, 2- methyl-2-propen-I-ol and propane -I ,2- diol). A systematic kinetic study showed that these reactions follow first order and fractional order in peroxodisulphate zero order in the above organic substrates and first order in silver ion concentrations. Also it was found that the presence of silver ion as catalyst increased the rate of the reaction. For these reaction, the activation energies Llli -1 05~ - 50kJ/mol , and other thermodynamic parameter, namely, the entropy change ~S* -I O~-I JIk, and free energy change ~G = 240-270kJ/mol were evaluated by using the values of rate constants at different temperatures. The analysis of reaction products revealed the presence of acid. Reaction path ways were proposed to explain the experimental observations.
