In the present research, we have made a survey on the influence of γ-rays (60Co sources) on the activity and selectivity of Pd/γ-Al2O3 (0,5-5% Pd) in the reaction of liquid phase hydrogenation of cyclohexene, nitrobenzol and phenylacetylene. The samples Pd/γ-Al2O3 have been prepared by impregnating method γ-Al2O3, previously calcined at 500°C for 4 hours with an aqueous solution of palladium chloride, followed by drying at 250°C. The resulting samples were recovered in a hydrogen stream for 2 hours at 500°C. The hydrogenation of unsaturated compounds was conducted in a thermo stated glass reactor-a catalyst "duck" in 96% ethanol at 10, 20, 30 and 40℃ with simultaneous measuring of the catalyst potential during the reaction relative to the saturated calomel half-cell.
