| Abstract | A new Versatile reagent TriButylAmmonium ChloroChromate(TriBACC) has been employed for the oxidation of Mandelic acid in perchloric acid medium. Rate of the réaction is catalysed by surfactants namely Benzalkonium chloride(BKC) and Sodium LaurylEther Sulphate(SLES). The Oxidation has been studied spectrophotometrically at room temperature.Rate of TriBACC oxidation of Mandelic acid has been followed under pseudo-first order condition. Rate constants were calculated by the integrated rate equation. The graph of logk versus time was linear and the slope is near to unity, rate constant calculated from graph also agreed with experimental value shows the first order rate dépendance on Mandelic acid. Product formed in this oxidation of Mandelic acid was analysed, Polymerisation test were carried out using Acrylonitrile and stoichiometric data has been evaluated.Temperature of the substrate is varried and from the rate constant value. Thermodynamic parameters like Activation energy, Enthalpy change,Entropy change and change in Gibb’s free energy is calculated.All the kinetic runs were repeated and the rate constants were reproducible within ±2% range. |
