目前无机盐和疏水性有机物在超/亚临界水中溶解度的研究虽已取得一定成果,但由于实验条件苛刻、设备要求高、操作难度大等问题,溶解度数据仍十分缺乏,无法满足现代工业应用要求,大大影响了超/亚临界流体技术在化学合成、萃取分离、环境工程等诸多领域的研究与开发进程,进一步确定高温高压水中物质的溶解度及其影响因素尚需要开展大量的基础研究工作.本文综述了无机盐和疏水性有机物在超/亚临界水中溶解度研究进展,并着重介绍了本课题组利用自行设计研发的耐高温高压微型可视毛细管反应器替代传统不锈钢材质高压反应釜或管式流反应器,结合显微放大观测技术、高精密冷热台、数字实时录像分析系统和拉曼光谱原位在线检测技术开展无机盐和疏水性有机物在超/亚临界水中溶解度研究工作取得的进展.
At present, some studies have been made on the solubility of inorganic salts and hydrophobic organic compounds in the supercritical / subcritical water but due to the harsh experimental conditions, high equipment requirements and difficult operation, the solubility data are still too scarce to meet the needs of modern industrial applications , Greatly influenced the research and development process of super / sub critical fluid technology in many fields such as chemical synthesis, extraction and separation, environmental engineering and so on, and further studies on the solubility and influencing factors of high temperature and high pressure water still require a lot of basic research. The research progress of solubility of inorganic salts and hydrophobic organic compounds in supercritical and subcritical water is reviewed. The research group focused on the use of high temperature and high pressure micro-visual capillary tube reactor designed by ourselves to replace traditional stainless steel autoclave or tube flow Reactor, combined with micro-amplification observation technology, high-precision hot and cold stations, digital real-time video analysis system and in-situ Raman spectroscopy in-situ detection of inorganic salts and hydrophobic organic matter in super and sub-critical water solubility research progress.
