Item The effect of antioxidative extracts on mitigating autoxidation of selected edible oils during deep frying(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 2017) Hemachandra, T.P.; Jayathilake, R.R.G.D.K.; Madhujith, W.M.T.Item Effects of method of manufacture on the oxidation of polyphenols and chlorophylls(The Tea Research Institute. Talawakele, 1965) Wickremasinghe, R.L.; Kirtisinghe, D.; Perera, K.P.W.C.; Perera, V.H.Item Oxidative dimerisation of Eugenol on Pt electrode in acetonitrile(University of Peradeniya. Peradeniya, 1995) Perera, J.S.H.Q. and othersElectrochemical investigation of eugenol on a polycrystalline platinum surface in an acetonitrile solution containing tetrabutylammonium tetrafluoroborate is described. The cyclic voltamogramme of the system, measured for an eugenol concentration of 2 mmol dm-3 at scan rate 500 mVs-1, consists of three oxidation peaks centred at 0.425,0.875 and 1.325V, with respect to saturated calomel electrode. The constant potential electrolysis of the system at + 1.325 V resulted in the complete conversion of eugenol to its dimer, which is formed by coupling through the benzene nucleus of eugenol. A plausible mechanism is proposed for this electrochemical conversion.
