| 摘 要： | 利用原位红外光谱技术记录了乙醇吸附在气相二氧化硅表面的变化过程。实验表明,在此过程中,乙醇在其表面发生化学吸附,并脱氢为表面乙醇盐。红外图谱表明,乙醇吸附在二氧化硅表面,可形成线式和桥式两种乙醇盐。同时,简单的讨论了二氧化硅表面存在的活性中心。

| Abstract: | In this paper,the adsorpting process of ethanol on fumed silica surface was recorded by infrared spectra technology.During the process,ethanol chemisorbed and dehydrogenated to form ethoxylates.And the FTIR spectroscopy indicated that the products were monodentate and bidentate ethoxylates.The active sites on bare silica were briefly discussed. |
