Progress of ionic liquids and supported palladium catalysts in the hydrogenation reactions
摘要
Abstract
Ionic liquids can be used as solvents,catalytic active sites,stabilizers,dispersants et al owing to their unique solvent performances,catalytic performances and designable structures. Supported palladium catalysts have many advantages such as high specific surface area,metal dispersion and good thermal stability,as well as problems of low selectivity of target selectivity,high cost and unclear reaction mechanism. Taking selective hydrogenation of phenol as the probe reaction,this paper summarizes the requirements for the catalysts and the advantages of palladium. Hydrogenation catalysts of phenol are divided into inorganic supported Pd catalysts,polymer supported Pd catalysts and ionic liquid-polymer supported Pd catalysts. The influences of carriers,ionic liquids,palladium salts,additives on the catalytic performance are analyzed. The results show that non-porous, polyfunctional alkaline carriers with certain microstructures,and certain elements such as P,N have better catalytic performance. And carriers with more basic sites are more likely to have higher activity and selectivity. Additives such as Na、K、Al、Ni、Ca、Cs et al can improve the catalytic performance while reducing costs. The hydrogenation performance of Pd(OAc)2is better than that of the other three. The application of ILs makes it easier to separate the catalysts from the reaction system,relieves the reaction requirements,and improves the activity and selectivity of catalysts. So the in-depth studies of ionic liquids in the catalytic hydrogenation process,catalytic hydrogenation mechanisms and catalyst stability are the primary directions in the future.关键词
