以甲基环己烷为原料，采用微波辅助球形碳球负载铂催化剂连续制氢，研究了该催化剂对以哌啶为代表的杂环化合物为代表的全饱和环烷烃的高效双芳构化反应。有效的脱氢是通过构建一个高强度的能量场，它作为一个反应位点，对碳珠（CB）支持的照射。该反应仅需10 W单频微波即可进行。该催化剂体系可连续使用至少12 h而催化剂活性无任何损失。脱氢芳构化反应也可以被催化，简单的环己烷衍生物，以及哌啶衍生物作为代表性的N-杂环烷烃，进行了测试。
A microwave (MW)-assisted method for the continuous production of hydrogen from methylcyclohexane using platinum on spherical carbon beads has been developed, and its application to the efficient dehydrogenative aromatization of fully saturated cyclic alkanes, including piperidines as representative heterocycles, has been studied. Effective dehydrogenation was achieved by the construction of a highly intense energy field, which acted as a reactive site, on the irradiation of the carbon beads (CB) support. The reaction could be carried out with only 10-W single-frequency MWs. The catalyst system could be used continuously for at least 12 h without any loss of catalyst activity. Dehydrogenative aromatization could also be catalyzed and simple cyclohexane derivatives, as well as piperidine derivatives as representative N-heterocyclic alkanes, were tested.
