以聚乙二醇为载体的催化剂及为反应介质的催化反应体系

Catalysts Supported on PEG and Catalytic Reaction Systems of PEG Used as a Reaction Medium

聚乙二醇(PEG)负载的催化剂具有较高的催化活性,易于回收和循环使用,因此受到人们极大的关注.此外,PEG可以用作催化反应的流动相动态地担载催化剂,通过“均相反应,两相分离”实现均相催化剂的简单分离.对这一领域的研究进展作一综述.

PEG-supported catalysts to exhibit high catalytic activity have gained significant attention. They can be recovered and reused conveniently. Furthermore, PEG could be used as a mobile phase supporting catalyst movably. The simple separation of homogeneous catalysts could be realized through monophasic catalysis coupled with biphasic separation. This paper reviews the advances in this research field.
