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 (α, β, π*) 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.
