The phenomena of critical concentration of boric acid and the oxidation reaction kinetics were studied on the formation of sec-dodecanol by the direct air oxidation of n-dodecane in the presence of boric acid. The critical concentration of boric acid in the oxidation reaction is found to be inversely proportional to an adsorption constant, , and found to increase with the reaction temperature. The activation energy of adsorption of the peroxy radical on the boric acid surface during oxidation is measured to be 19.87 kcal/mol. The oxidation reaction shows a first-order dependence with respect to n-dodecane concentration in the steady-state activity regime. The experimental results are in good agreement with the predicted values from the proposed reaction kinetic model.
