Abstract

Abstract The effect of cationic surfactant on the oxidation of galactose by N-bromophthalimide in the presence of acidic medium at 308 K has been studied. The order of reaction with respect to [Gal], [oxidant], and [H+] were found to be fractional, first, and negative fractional order, respectively. The effects of KCl, KBr, phthalimide and mercuric acetate have also been studied and summarized. 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.
