摘要
水是一种环境友好的反应介质,超(近)临界水中的反应已成为目前研究的一个热点。原位反应技术是深入研究超(近)临界水中反应过程的重要手段之一,其中金刚石压腔和毛细管技术是目前最常用的主要方法,与拉曼光谱、红外光谱、质谱等分析方法联用,可以对超(近)临界水中反应机理进行研究。本文综述了超(近)临界水中的原位反应观测技术,介绍了金刚石压腔的结构和工作原理、金刚石压腔和毛细管的应用范围,阐述了金刚石压腔和毛细管技术在原位观测和反应机理研究方面的应用。最后,展望了超(近)临界水原位反应技术的应用前景。
Water is an environmentally friendly reaction medium,and the reactions in supercritical(subcritical) water become a hot subject of current research.In-situ reaction technique,especially diamond anvil cell(DAC) and capillary which are used combining with such instruments as laser Raman,infrared spectroscopy and mass spectrograph,is one of the important methods to deeply study reaction mechanism in supercritical(subcritical) water.In this paper,in-situ reaction techniques for looking into the reaction course in supercritical(subcritical) water are reviewed.The structure and working principle of the diamond anvil cell,and the scope of application of DAC and capillary,as well as applications of DAC and capillary to the reaction mechanism research are introduced.At last,the prospect of in-situ reactions technique used in supercritical(sub-critical) water is discussed.
