摘　　要：与传统的萃取器相比,微通道萃取器的表、界面效应更加明显,过程可控性更强;两相接触的相界面积更大,萃取过程达到相平衡所需的时间更短,萃取效率更高;设备高度集成,放大效应小,安全性更高。鉴于微通道反应器的诸多优点,近年来其在萃取领域引起了学者的广泛关注。本文介绍了微通道反应器的微混合构件类型及微通道内流体流型,综述了微通道萃取技术的研究进展,分析了微通道萃取技术存在的问题,展望了微通道萃取技术的发展方向,以期为相关学者的后续研究工作提供方向和指引。Compared to traditional extractor,microchannel extractor has more obvious surface/interfacial effect,stronger process controllability,larger interfacial area,shorter phase equilibrium time,higher extraction efficiency,higher equipment integration,smaller scale-up effect and higher security.It has aroused widespread concern about extraction in microchannels due to these advantages.Mixed microstructure and flow patterns of microchannel extractors are introduced firstly.Then,research advances of extraction in mircochannels are reviewed.Furthermore,the existing problems of extraction in mircochannels are analyzed.Finally,the development trends of extraction in mircochannels are discussed.It can provide direction and guidance for the subsequent research.
