Liquid-phase oxidation of n-dodecane in the presence of boric acid

Abstract: 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… Show more

“…Paraffinic hydrocarbons, which have C-C and C-H bonds that mimic those in petroleum base oils, are excellent model reactants. Many studies have focused on the oxidation of simple hydrocarbons to elucidate reaction pathways, kinetics, and mechanisms (e.g., Garcia-Ochoa et al, 1989;Lee et al, 1987; Brown and Fish, 1969; Van Sickle, 1972; Van Sickle et al, 1973; Suresh et al, 1988;Mill et al, 1972; Korcek et al, 1972;Jensen et al, 1979Jensen et al, ,1981; Hombek et al, 1989; Reddy et al, 1988; Hazlett et al, 1977). Much of this work, 0888-5885/92/2631-0069103.00/0 however, was limited to the initial stages of the oxidation, where the hydrocarbon concentration remains essentially constant and hydroperoxides are the major oxidation product.…”

“…Active oxygen during the oxidation was quantified by iodometry. Autoxidation was performed in the absence [13,14] and presence of antioxidants [15]. Antioxidants are interchangeably called inhibitors.…”
