Abstract

This paper reviews the use of Spanish sepiolites as supports for Pd catalysts employed for the reduction of variously substituted alkenes, the selective semi-hydrogenation of phenylacetylene and the reduction of acetophenone, both with gaseous hydrogen and by hydrogen transfer with cyclohexene as donor. The performance of Pd/sepiolite catalysts is compared with that of synthesized catalysts supported over SiO₂, SiO₂AlPO₄, AlPO₄ and AlPO₄Al₂O₃, which we have used extensively, as well as with that of several commercially available catalysts from Fluka, Merck and Degussa.

海泡石作为有机还原过程中钯催化剂的载体

本文综述了以西班牙海泡石为载体的钯催化剂在以气态氢和以环己烯为供体的氢转移还原各种取代烯烃、苯乙炔选择性半加氢和苯乙酮还原中的应用。将Pd/海泡石催化剂的性能与我们广泛使用的SiO2、SiO2AlPO4、AlPO4和AlPO4Al2O3负载的合成催化剂的性能以及Fluka、Merck和Degussa的几种市售催化剂的性能进行了比较。

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.
