氟两相体系在催化中的应用

氟两相催化体系（FBC）是一种新型均相催化剂固定化（多相化）和相分离技术。氟两相催化体系在较高温度时可以互溶成单一相从而为化学反应提供优良的均相反应条件,降低温度体系又可恢复为两相,只需经过简单的相分再即可实现反应产物的分离、提纯和催化剂的再生。独特且对环境友好的性能使氟两相体系在诸多领域显示出广泛的应用前景。介绍了氟两相催化体系的概念、特性,并对其在催化反应、有机合成、产物分离等方面的研究进展进行了综述,对其应用前景作了预测。

Application of fluorous biphase in catalysis

The FBC(fluorous biphase catalysis) is a new nonaqueous immobilization and phase-separation tech-nique. Above a certain temperature, the FBC mixes to form a single phase and thus provides the best conditions for the desired reaction. The reaction system is again biphasic upon subsequent cooling, catalyst recovery can then be achieved and organic reaction products can be readily separated. For the unique and enviromentally friendly charac-ter, FBC shows a wide application in many areas. In this paper, the concept, specific properties of FBC are intro-duced. The progress in the research of FBC on catalysis, organic synthesis, phase separation of products are reviewed, and further applications of FBC are also predicted.
