研究了磺酸功能化离子液体在缩醛（酮）反应中的催化性能．系统考察了离子液体催化剂、反应时间、反应温度、底物用量比和催化剂用量等因素的影响以及底物的适用性．研究结果表明：磺酸功能化离子液体[C4H8SO3Hmim]p—TSA是缩醛（酮）反应有效的催化剂，其催化活性主要由阳离子决定；该催化体系具有很好的重复使用性，经十次循环后催化活性未见明显降低．
英文摘要：
The application of functionalized ionic liquids in acetalization reaction is investigated. The effects of ionic liquids, reaction time, temperature, mole ratio of regents and the amounts of catalyst are examined. The acetalization and ketalization of various aldehydes and ketones with alcohols are also studied. The functional ionic liquid [ C4H8SO3Hmim]p-TSA is proved to be efficient catalyst in protection of aldehydes whose catalytic activity is mainly determined by the cation. Moreover, the catalyst can be reused for 10 times without obvious loss of its activity.
