THE OXIDATIVE DEHYDROGENATION OF CYCLOHEXENE CATALYZED BY ZRCU(PO4)2 Academic Article

abstract

• A kinetic study of the oxidative dehydrogenation of cyclohexene with ZrCu(PO4)2 as catalyst was carried out. The reaction was found to be first order with respect to both oxygen and hydrocarbon. Activation energies were 11.7 0.4 kcal/mole for the formation of benzene and 6.5 0.3 kcal/mole for the complete oxidation to CO2 and water. In the absence of oxygen, dehydrogenation takes place with reduction of Cu(II) to copper metal. If the reaction is carried out in a two-step sequence in which the hydrocarbon is first sorbed on the catalyst and then contacted with oxygen, complete burn up of the hydrocarbon is observed. In the reverse sequence in which oxygen is sorbed first high yields of benzene were obtained. A qualitative explanation of possible mechanisms for these reactions is presented. 1986.
