Abstract
الملخص الانجليزي The present work comprises a study of the kinetics and mechanism of oxidation of l,8-dihydroxynaphthalene-3,6-disulfonic acid (CTA) (chromotropic acid) (HO)2C10H4(SO3Na)2and l-amino-4-naphthalene sulfonic acid (ANS) (NH2C10H6SO3Na), by potassium peroxodisulphate. l. In chapter I, electron transfer, outer-sphere and inner-sphere mechanisms have been discussed. The nature, chemical behavior and different species in aqueous solutions of peroxodisulphate have been reported. The literature concerning peroxodisulphate organic and inorganic oxidation some formula of naphthalene sulfonic acid used in dyes. The nature and properties of chromotropic acid and amino-naphthalene sulfonic acid have been briefly discussed. 2. Chapter II, encompasses the chemicals, the experimental procedures and the technique for the kinetics studies. Also including methods of analysis of the kinetic data. 3. Chapter III, comprises the layout of the results obtained and their discussion. The effect of various parameters on the rate of reaction has been discussed. This chapter contains two parts : I) In the first part, the kinetics of oxidation of (HO)2c10H4(SO3Na)2 by peroxodisulphate have been studied in aqueous solutions. The reaction rate «2S round to be increases with increasing ionic strength and independent on [OH]. The rate of reaction is zero-order dependence with respect to the organiccompound concentration and first-order dependence on the peroxodisulphate concentration. The mechanism of these kinetic results was proposed with the homolytic fission of S2o82- is the rate-determining stepthe activation parameters ∆H*, ∆S* for the electron-transfer I pathway have been calculated using the transition state theory equation (Erying Equation). The effect of methanol-water solvent mixtures on the kinetics of oxidation of (CTA) have been studied. The rate of reaction decreases by increasing methanol content and explained on the basis of the polarity of solvent. II) In the second part, the kinetics of oxidation of (NH2C10H6S03Na) by K2S2O8 in aqueous solutions have been studied. The rate of reaction is independent on the [OH] and increase with ionic strength. The oxidation of this organic compound obeys the rate law, Rate = k1[ANS] [S2082 -] The rate law is consistent with the proposed mechanism, where the Electron transfer may proceeds via inner sphere pathway.The enthalpy of activation∆H* and entropy of activation ∆S* were also calculated. In methanol-water solvent mixtures, the rate of reaction was found to be decreases with increasing methanol content. These results was discussed on the basis of polarity of the solvent.
