A Hydrodynamically Controlled Interface for Phase Transfer Catalysis & Related Processes

该项目研究了用于相转移催化（PTC）和相关反应输运系统研究的液-液接触装置的流体动力学和输运特性。固体-液体PTC的研究正在向液体-液体PTC的方向发展。利用电化学示踪技术研究了水流之间和水相与有机相之间的传质。用新获得的激光多普勒测速仪研究了径向速度的垂直分布。研究了流体动力不稳定性在层流接触装置中的作用。该结果可用于各种工业有机合成，用于生产聚合物，杀虫剂和药物。

The project examines the hydrodynamics and transport properties of a liquid-liquid contacting device for the study of phase transfer catalysis (PTC) and related reactive- transport systems. Research on solid-liquid PTC is now continuing with liquid-liquid PTC. Mass transfer is studied between aqueous streams and between aqueous and organic phases with the use of an electrochemical tracer technique. The vertical distribution of radial velocities is investigated with a recently acquired laser-Doppler velocimeter. The role of hydrodynamic instabilities in the laminar-flow contacting device is examined. The results are useful in various industrial organic syntheses for the production of polymers, pesticides, and pharmaceutical.
