A series of alkyltributylphosphonium chloride ionic liquids, prepared from tributylphosphine and the respective 1-chloroalkane, CnH2n+1Cl (where n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12 or 14), is reported. This work is a continuation of an extended series of tetraalkylphosphonium ionic liquids, where the focus is on the variability of n and its impact on the physical properties, such as melting points/glass transitions, thermal stability, density and viscosity. Experimental density and viscosity data were interpreted using QPSR and group contribution methods and the crystal structure of propyl(tributyl)phosphonium chloride is detailed.
一系列烷基三丁基氯化鏻离子液体,由三丁基膦和相应的 1-氯烷烃 CnH2n+1Cl (其中 n = 1、2、3、4、5、6、7、8、9、10、12 或 14)制备,被报道。这项工作是四烷基鏻离子液体系列的延续,重点是 n 的变化及其对物理性质的影响,如熔点/玻璃化转变、热稳定性、密度和粘度。使用 QPSR 和基团贡献方法解释了实验密度和粘度数据,并详细介绍了氯化丙基(三丁基)鏻的晶体结构。
