摘要： Ionic liquids of the structure Q+A−, in which Q+ is a 1,3-dialkylimidazolium ion, in which the alkyl groups, independently of one another, are linear C1-C4-alkyl groups and A− is the anion of an acid HA with a pKa of less than 3, can be purified by desorption of volatile compounds at a temperature of 100 to 200° C. and a pressure of at most 100 mbar over a period of at least 0.1 h and be used for dehumidifying air.
摘要翻译： 结构Q + A-的离子液体，其中Q +是1,3-二烷基咪唑鎓离子，其中烷基彼此独立地是直链C 1 -C 4 - 烷基，而A-是酸的阴离子 具有小于3的pKa的HA可以通过在100至200℃的温度下解吸挥发性化合物并在至少0.1h的时间内至多100mbar的压力来纯化并用于除湿空气。
