设计合成了三类N-甲基二乙醇胺（MDEA）-二元羧酸离子液体水溶液，研究了它们的物理性质和SO2吸收容量。结果表明：MDEA/有机酸的摩尔比及阴离子种类是影响吸收容量的主要原因。碱酸摩尔比越高，离子液体吸收能力越强，解吸能力越差且解吸时间也越长。此外，不同阴离子的离子液体溶液吸收SO2的容量有如下关系：MDEA-丁二酸＞MDEA-戊二酸＞MDEA-苹果酸。对于MDEA-戊二酸和MDEA-苹果酸离子液体溶液，最具工业化应用前景的碱酸摩尔比分别为1.2：1和1.4：1。

Three types of N-methyldiethanolamine (MDEA)-bicarboxylic acid ionic liquid (IL) aqueous solutions were designed and synthesized. The physical properties of these solutions were characterized and the SO2 absorption capacities were investigated. It was found that the molar ratio of MDEA to bicarboxylic acid, as well as anion type, had a great influence on the absorption capacity of the IL solutions. The larger the molar ratio, the higher the SO2 absorption capacity of the solutions. However, the desorption capability of the IL solutions decreased with increasing molar ratio. The IL solutions of different anions had the order of absorption capacity as follows:MDEA-succinic acid ILs>MDEA-glutaric acid ILs>MDEA-malic acid ILs. As far as MDEA-glutaric acid and MDEA-malic acid ILs were concerned, the most promising industrial molar ratios of alkali to acid were 1.2:1 and 1.4:1, respectively.
