功能化离子液体在室温下催化醛(酮)与二元醇的缩合反应
Acetalization of aldehydes (ketones) with diols catalyzed by functional ionic liquids under room-temperature
摘要
Abstract
Some functional ionic liquids (FILs) composed of 1-methyl-3-propane sulfo-imidazolium salts were synthesized and used as solvent-catalyst dual system for acetalization of aldehydes (ketones) with diols. The model reaction was carried out based upon molar ratio of raw material cyclohexanone and the FILs catalyst as 50: 1. The optimized conditions of the condensation reaction were identified as : 1 : 1.5 molar ratio of cyclohexanone and 1,2 - propanediol, under reaction temperature 20℃ for 0.1 h. The conversion achieves 97% and the reaction process is free of any organic solvent and water stripping agent. The condensation reactions of the other aldehydes (ketones) with other diols were also explored. After completion of the reaction, the product can be separated from the catalyst simply by decantation, and the catalyst can be recycled and reused for several times without noticeable decreasing of activity.关键词
