Study Of Glass Fiber-supported Metal Complexes For Use In Catalysis

Green chemistry is the final demand for sustainable development of environment and resource. In order to reduce pollution and save resource, green chemistry applies new chemical technology to change the original process of chemistry and fundamentally to avoid pollution,achieving both the environmental protection and economical development. Most of the chemical industry process is inseparable from catalysts. New catalyst can boost the activity of chemistry reaction and reduce the energy consumption. Therefore, catalysis is the key period of green chemistry. Cleaning is an important component of green chemistry in organic synthesis. Till now,most studies are concentrated upon the homogeneous catalysis. However, it is difficult to part the catalysts from the products and to reuse the catalysts. So for, the study, the transition metal complexes are immobilized on supports for the preparation of heterogeneous catalysts, has received widespread attention.In this paper, using multi-step methods, three GF-supported metal complexes are synthesized, in which copper and manganese are the central atoms. Moreover, the complexes are characterized by the FT-IR spectroscopy, HNMR, SEM, thermogravimetric analysis, ICP-AES,etc. The catalytic performances of the GF-supported copper and manganese metal complexes are studied, and with the styrene epoxidation reaction as a criterion, the different reaction conditions such as reaction time, the amount of oxidant H2O2 and recycling number are investigated in detail. At the some time, a study on the catalytic performance of fiber-supported palladium metal complexes for Heck reaction is also carried out.The GF immobilized metal catalysts not only have catalytic reaction efficient, but also can reuse, simplifying the reaction process, reduce the cost of the reaction, according to the trend of the development of green chemistry.
