摘　　要：由乙醇胺、二乙醇胺、三乙醇胺提供阳离子,甲酸、乙酸、乳酸提供阴离子,合成了一系列醇胺类离子液体,并对其进行了核磁共振氢谱和红外光谱表征并确认。将常规水浴法、冰水浴法、微波法进行比较,并对水浴条件下反应温度、反应时间对收率的影响进行了考察。最佳反应条件如下:反应时间为20 h,水浴温度为5℃。A series of hydroxyl ammonium ionic liquids were synthesized from cation coming from ethanolamine,diethanolamine,and triethanolamine and anion from lactic acid,acetic acid and formic acid,and confirmed by 1H NMR and 13 C NMR.This research made a comparison among conventional water-bath method,ice water-bath method and microwave water-bath method.In addtion,an investigation of the effect of water-bath temperature and time on recovery rate was carried out.The results suggest that the optimal synthesis conditions are 5 ℃ and 20 h.
