Kinetics and Mechanism of Propane-1,3-Diol Oxidation By Mn(Vii) in Aqueous Medium

The oxidation of propane-1, 3-diol by potassium permanganate in aqueous solution was investigated at λmax 525 nm. the rate of the reaction was found to increase with increase in [kmno4] and [propane-1, 3-diol]. the reaction showed first order dependence each in [kmno4] and [propane^-1, 3-diol] and independent in the ionic strength of the solution. the values of 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 and ftir analysis revealed the product of the reaction to be 3-hydroxy-propanone.
