Study of the competition between disproportionation and oxidation of cyclohexene in the liquid phase over solid catalysts
A study has been made of the liquid phase conversion of cyclohexene over metallic palladium and platinum catalysts under oxygen and nitrogen atmosphere. Special attention has been given to the effect of oxygen pressure, catalyst support, solvent and metal modifiers on the activity of metal catalysts and distribution of products. In every case the main reaction pathway is disproportionation of cyclohexene to benzene and cyclohexane. Formation of oxygenated products is low even at 2–6 atm of oxygen. Doping of Pd and Pt catalysts with metal modifiers strongly suppresses the conversion of cyclohexene and has no influence on the ratio of benzene/cyclohexane at experiments carried out in an inert atmosphere. An interpretation of these effects is presented.
期刊介绍：
Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes.
The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
