Abstract
The oxidation of benzhydrol (BH) by tetrabutylammoniumbromochromate (TBABC) was studied in the presence of perchloric acid, in water/organic solvent mixtures of varying excess molar free energy function. The reaction is first order with respect to both TBABC and acid. The reaction rates were determined at different temperatures and the activation parameters computed. A correlation of data with the Kamlet-Taft solvatochromic parameters (alpha,beta,pi*) suggests that the specific solute-solvent interactions play a major role in governing the reactivity. The reaction does not induce polymerization of acrylonitrile. The product of oxidation is benzophenone. Based on the kinetic results and product analysis, a suitable mechanism has been proposed for the reaction of TBABC with benzhydrol.
