Experimental data for density, viscosity, refractive index and surface tension of four phosphonium-based ionic liquids were measured in the temperature range between (288.15 and 353.15) K and at atmospheric pressure. The ionic liquids considered include tri(isobutyl) methylphosphonium tosylate, [P ][Tos], tri(butyl)methylphosphonium methylsulfate, [P][CHSO], tri(butyl)ethylphosphonium diethylphosphate, [P][(CHO)PO], and tetraoctylphosphonium bromide, [P][Br]. Additionally, derivative properties, such as the isobaric thermal expansion coefficient, the surface thermodynamic properties and the critical temperatures for the investigated ionic liquids were also estimated and are presented and discussed. Group contribution methods were evaluated and fitted to the density, viscosity and refractive index experimental data.
在288.15至353.15 K的温度范围内和大气压下，测量了四种鏻基离子液体的密度、粘度、折射率和表面张力的实验数据。所考虑的离子液体包括三（异丁基）甲基鏻对甲苯磺酸盐[P ][Tos]、三（丁基）甲基鏻甲基硫酸盐[P][CHSO]、三（丁基）乙基鏻二乙基磷酸盐[P][(CHO)PO]和四辛基鏻溴化物[P][Br]。此外，还估算了所研究离子液体的衍生性质，如等压热膨胀系数、表面热力学性质和临界温度，并进行了展示和讨论。对基团贡献法进行了评估，并将其与密度、粘度和折射率的实验数据进行拟合。
