The effect of cationic surfactant (CPC) on the oxidation of D-Xylose by N-bromophthalimide in the presence of acidic medium at 308 K has been studied. The order of reaction with respect to [D-Xylose] was found to be fractional. First and negative fractional order with respect to [oxidant] and [H+] was found respectively. The presence of inorganic salts (KCl, KBr) exhibits a severe hike in the reaction rate. Retardation effect of phthalimide has also been studied. Mercuric acetate as scavenger in the temperature range of 298-318 K has been reported. The rate of reaction decreased with an increase in dielectric constant of the medium. The effect of cationic surfactant cetylpyridinium chloride (CPC) has been studied. CPC retards the rate of reaction. Thermodynamic and activation parameters have been evaluated. Stoichiometry and Product analysis has been studied. A suitable mechanism in conformity with the kinetic data has been proposed.
