温控两相酸性聚合型离子液体催化胺醛缩合反应
Thermoregulated Biphasic Acidic Polymeric Ionic Liquid Catalyzed Amine Aldehyde Condensation Reaction
摘要
Abstract
Acidic polymeric ionic liquid was synthesized with polyethylene glycol as the main chain and imidazole-based ionic liquid as crosslinking agent through the free radical polymerization to reduce the loss rate of catalyst.The thermoregulated biphasic system comprised of ionic liquid and toluene was used for the condensation reaction of aniline and benzaldehyde.The catalytic results show that the catalyst has advantages of high catalytic activity, small loss and easy recycling.The yield of N-benzalaniline is 93.4%, and the average loss rate of ionic liquid is about 2.5%.Further tests show that the system has good universality for the various substrates, and the yield of the products is 57.2%~82.9%.关键词
