  • 摘要: 将液体吸附原位红外表征系统与红外光谱仪连接,是实现原位红外反应过程的重要技术环节. 原位红外表征过程中涉及的吸附液存储于液体吸附原位红外表征系统内,对一些沸点较高的液体可以通过加热套控温操作完成吸附,并在被测物质吸附反应过程中监测其结构变化. 系统可设置多个液体吸附池,实现在同一试验过程中进行多种液体切换吸附,满足被测物质吸附不同液体蒸汽的需求,还可以使被测物质吸附液体蒸汽,对固体表面进行惰性气体前处理或氢气还原处理. 最终通过原位红外监测出反应产物,实现液体吸附原位红外表征.

     

    Abstract: Connecting the in-situ infrared characterization system of liquid adsorption with the infrared spectrometer is an important technical link to realize the in-situ infrared reaction process. In-situ infrared characterization process involves the adsorption liquid stored in the in-situ infrared characterization system of liquid adsorption, which can simultaneously complete the adsorption of some liquids with high boiling point by heating a set of temperature control operation, so as to achieve the monitoring of the structural changes during the adsorption reaction of the measured substances. A number of liquid adsorption tanks in the system can be set up, which can carry out a variety of liquid switching adsorption in the same experimental process to meet the adsorption of different liquid vapors by the substance under test, as well as the adsorption of liquid vapors by the substance under test and inert gas pretreatment or hydrogen reduction treatment on the solid surface. Finally, the reaction products were detected by the in-situ infrared monitoring, and the in-situ infrared characterization of the liquid adsorption was realized.
