合成γ-丁内酯Cu-Zn-Al-O催化剂的ESR的研究
ESR STUDY OF Cu-Zn-Al-O CATALYSTS FOR γ-BUTYROLACTONE SYNTHESIS
【摘要】 本文运用ESR方法研究了Cu-Zn-Al-O催化剂的表面结构,考察了1,4-丁二醇在该催化剂上反应过程中的原位ESR谱及反应后放置过程催化剂表面的ESR变化。确证在该催化剂上的1,4-丁二醇脱氢反应是自由基反应机理。
【Abstract】 ESR Spectra has been used to examine the surface chemical state of Cu-Zn-Al-Ocatalyst for Y-butyrolactone synthesis. The reaction mechanism of the dehydrocyclization of 1,4-butanediol to Y-butyrolactone with Cu-Zn-Al-O as the catalyst in the liquid phase is exam-ined and speculated by in-situ ESR- And the ESR results provide a proof for the free radicalreaction mechanism of the alcohol dehydrogenation.
