1.A comparative study has been made of the catalytic properties of Tc, TcO2, and TcS2 in the decomposition reactions of isopropanol and cyclohexane.2.In the dehydrogenation of isopropanol the oxide catalysts occur in the order for a decrease in activity: TcO2/?-Al2O3 >TcO2/MgO > TcO2/ZrO2-TcO2/Y2 O3 > TcO2/Cr2O3.3.The decomposition of isopropanol on the supported metallic and oxide catalysts takes place in the direction of dehydrogenation, while dehydrogenation and dehydration take place on the sulfide catalyst.4.For catalysts based on Tc, TcO2, and TcS2 the yield of benzene in the dehydrogenation of cyclohexane depends on the nature of the supported technetium compound and the nature of the substrate. In their activity in this process the technetium compounds can be arranged in the following order Tc > TcO2 > TcS2. |
