Kinetics and Thermodynamics of Oxidation of Benzhydrol by Tetrabutyl Ammonium Bromochromatein the Presence of Oxalic Acid

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 determined at different temperatures between 298 and 313 K and the activation parameters were calculated. Further, a suitable mechanism has been proposed based upon the experimental results.

Study on Catalyzed Tungstophosphoric Acid oxidation of p-Chloro Benzhydrol and p-Methyl Benzhydrol by N-Bromoisonicotinamide in Aqueous Acetic Acid Medium

“…Literature survey reveals that Tungstophosphoric acid (TPA) due to its thermal stability and acidity makes it efficient and ecofriendly catalyst in oxidation of organic compounds such as aromatic amines 6 , aromatic alcohols 7 , allyl alcohols 8 , oximes 9 etc. Review of literature benzhydrol by NBP 10 , 4-MPDC 11 , selenium dioxide 12 , Permanganate 13 , tributylammonium chlorochromate 14 , chromium (VI) oxide 15 , tetrabutylammonium bromochromate 16 and BromamineT 17 etc. have been reported.…”
