Abstract:
The kinetics of oxidation of benzhydrol (BH) by tetrabutylammonium bromochromate (TBABC) was described. Product analysis confirmed the formation of benzophenone. The reaction has been studied in the presence of oxalic acid (OA). The reaction was run under pseudo-first-order conditions. The rate of reaction is first order with respect to TBABC, BH and [H+] in the presence of oxalic acid (OA). Rates of oxidation of BH were determinedat different temperatures between 298 and 313 K andthe activation parameters were calculated. Further, a suitable mechanism has been proposed based upon the experimental results.
