چکیده
|
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 on the ionic strength of the solution. the activation parameters were evaluated from arrhenius and erying’s equations and the values of〖δh〗 ^#(kj mol-1), 〖δs〗^#(kjk-1 mol- 1) and〖δg〗^#(kjmol-1) were 24.98, -0.22 and 90.50 respectively. negative entropy of activation revealed an association mechanism and an ordered transition state for the reaction. stoichiometric study showed 1:1 consumption of kmno4 and propane-1,3-diol. spectroscopic studies and ftir analysis revealed the product of the reaction to be 3-hydroxyl-propanal. a suitable reaction mechanism was proposed for the reaction investigated.
