Abstract:
The oxidation of propane-1,3-diol by potassium permanganate in aqueous solution have been studied at λmax 525 nm. The rate of the reaction has been found toincrease with increase in [KMnO4] and [Propane-1,3-diol]. The reaction shows first order dependence both on [KMnO4] and [Propane-1,3-diol] and independent on the ionic strength of the solution. The ΔH#(kJ mol-1), ΔS# (kJK-1mol-1) and ΔG#(kJ mol-1) were 24.98, -0.22 and 90.50 respectively. Negative entropy of activation revealed an ordered transition state for the reaction. Spectroscopic studies showed the product of the reaction to be 3-hydroxyl-propanal. A plausible mechanism in consonance with spectroscopic studies and kinetic result was proposed.
