首发时间:2015-04-29
摘要:本文用L-谷氨酸和醋酸钴(II)合成了谷氨酸-钴(II)配位物的晶体,并将该3D配位物应用于活化分子氧的氧化研究。在以环己烯为底物,氧气为氧源,无溶剂体系中,70 C下反应24 h后,环己烯的转化率达到46.0%。经气质联用分析氧化产物为环氧环己烷、2-环己烯-1-醇及2-环己烯-1-酮,根据配合物的结构分析得知,配合物结构中配位H2O的存在,使得该3D配合物对分子氧具有很好的活化能力。

Property of L-glutamate acid cobalt(II) complexes to activate molecular oxygen
Abstract:In this study, glutamate acid cobalt(II) crystal was synthesized by using L-glutamate acid and cobalt acetate, and the activate molecular oxygen behaviors of the synthesized complex for the oxidation of cyclohexene were examined. The synthesized crystal yield a conversion rate of 46.0% at 70 C after 24 h, results in the formation of the following products: cyclohexene oxide, 2-cyclohexene-1-ol and 2-cyclohexene-1-one. Therefore, the results indicate that the prepared 3D complex has good ability on activation of molecular oxygen.
Keywords: Glutamate acid cobalt(II) complex activation of molecular oxygen cyclohexene
