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 to increase 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 activation of entropy revealed an ordered transition state for the reaction. Spectroscopic studies showed the product of thereaction to be 3-hydroxy-propanal.
