介绍了一种新的离子液体合成法—水浴微波法,以乙醇胺、二乙醇胺、三乙醇胺和N,N-二甲基乙醇胺为阳离子,甲酸、乙酸和乳酸为阴离子,合成一系列醇胺类离子液体.以乙醇胺乳酸盐离子液体为例,通过正交实验(L_9(3~4))分析,得到最佳合成条件为:合成时间30 min,温度65℃,微波功率300 W,乙醇胺与乳酸的摩尔比1:1.1.在此条件下,除N,N-二甲基乙醇胺类离子液体外,其余8种离子液体产率均保持90%以上.乙醇胺乳酸盐对SO_2具有较高的吸收容量,吸收的SO_2与乙醇胺乳酸盐的摩尔比为1.063,选其作为最佳吸收剂进行脱硫性能研究.研究发现,适宜吸收温度为25℃,解吸温度和解吸时间分别为90℃和60 min.实验同时表明,水浴微波法可以加速SO_2的解吸过程. |

A novel water-bath microwave method used for synthesis of hydroxyl ammonium ionic liquids was reported.A series of hydroxyl ammonium ionic liquids (ILs) consisting of ethanokmine, diethanolarnine, triethanolamine or dimethylethanolamine as cations, and formic acid, acetic acid or lactic acid as anions were synthesized.Taking ethanolamine lactate ionic liquid as an example, the result of orthogonal experiment (L_9(3~4)) showed the optimal synthesis conditions were 65℃, wave power of 300 W for 30 min with the molar ratio of 1:1.1 (ethanolamine vs lactic acid).Under these conditions, the yield of the other eight ILs except dirnethylethanolamine salts reached above 90%.Because of its higher capacity for absorption of SO_2, ethanolamine lactate was selected as the better absorbent with the capacity of SO_2 in ethanolamine lactate 1.063 (SO_2 vs ethanolamine lactate).The results showed that the appropriate absorption temperature for SO_2 was 25℃, desorption temperature was 90℃, and desorption time was 60 min.It was also found that water-bath microwave was able to accelerate the desorption of SO_2. |
