The oxidative dehydrogenation of alicyclic diene hydrocarbons refers to scarcely studied heterogeneous catalytic reactions which proceed with the participation of oxygen. The dehydrogenation of methylcyclopentane is an endothermic reaction. To improve the reaction kinetics, this research was to develop a structured catalyst by conductive metals (Cu, Zn, Co, Cr) support which could hold an adherent catalytic layer. The active phase was impregnated onto these support metals and the developed catalyst was tested for the dehydrogenation of methylcyclopentane. The catalyst preparation involved three main key steps which were support oxidative reaction, loading of active particles on the catalyst surface, preparation of an active catalyst layer on the surface finally bringing the catalyst into the active phase. Different types of catalyst activation and deactivation mechanisms stability have been studied in this investigation. The advantage of this works, the oxidative dehydrogenation of methylcyclopentane is that it occurs at the expense of oxygen in the air. The zeolite structure study helped identify the effect of the combination of catalysts, and adsorption of metals on clinoptilolite and dispersion on the selectivity of the catalyst particles. Numerical values of the kinetic parameters were calculated

The arylation reaction of ethylene by toluene has been studied in the liquid phase with the using of the homogeneous catalytic system Pd(OAc) 2 +Cu(OAc) 2 +PPh 3 , in the semibatch flask reactor under atmospheric pressure. Optimum conditions for the reactions were as follows: mole ratio of the components of the catalytic system Pd(OAs) 2 :Cu(OAc) 2 :PPh 3 =1:2:0.03, concentration of the active mass of the catalytic system, [Pd(OAc) 2 ]=6·10 -2 ÷10 -3 mol/l, temperature (95÷105) 0 C. In these conditions the yield of vinyltoluene is (5÷8) wt.%. It has been proposed as a posible mechanism for the reaction including the formation of the intermediate complexes of palladium acetate with toluene, ethylene and triphenyl phosphine.

The catalytic activity of modified natural clinptilolite zeolite has been studied in the oxidative dehydrogenation of methylcyclohexanol to ethylcyclohexanone. On the basic of experimental studies it was found that natural clinoptilolite modified with Cu2+ and Pd2+ cations exhibit high activity and selectivity in the reaction under con-sideration. Clinoptilolite containing 0.15 wt.% Pd2+ and 0.5 wt.% Cu2+ is the most ac-tive for the studied reaction. It was studied the kinetic regularities of the reaction over the selected catalyst. Based on literature material and own experimental data was suggested the stage scheme of the mechanism of the reaction and developed theoretically based kinetic model of the process.
