测定了LiNO 3：[BMIM]Cl = 2：1的LiNO 3/[BMIM]Cl/H2O三元体系的结晶温度、蒸气压、密度、粘度和比热容。结晶温度从w = 0.65至0.75测量。在w = 0.55 ~ 0.75和298.15 ~ 416.45K范围内测得蒸汽压。在w = 0.55 ~ 0.75和293.15 ~ 373.15K范围内测量了密度、粘度和比热容。通过最小二乘法获得测量值的回归方程。结果表明，LiNO 3/[BMIM]Cl/H2O的蒸气压与LiNO 3/H2O的蒸气压几乎相同，但质量分数低10%。LiNO 3/[BMIM]Cl/H2O的晶化温度远低于具有相同吸收能力的LiNO 3/H2O。LiNO_3/[BMIM]Cl/H_2O是一种很有潜力的工作对。
The crystallization temperature, vapor pressure, density, viscosity, and specific heat capacity for the ternary system of LiNO3/[BMIM]Cl/H2O with a mass ratio (LiNO3:[BMIM]Cl) of 2:1 were measured. The crystallization temperature was measured from w = 0.65 to 0.75. The vapor pressure was measured from w = 0.55 to 0.75 and 298.15 to 416.45 K. The density, viscosity, and specific heat capacity were measured from w = 0.55 to 0.75 and 293.15 to 373.15 K. Regression equations for the measured values were obtained by a least-squares method. Results showed that LiNO3/[BMIM]Cl/H2O had vapor pressure nearly identical to that for LiNO3/H2O at a 10% lower mass fraction. The crystallization temperature for LiNO3/[BMIM]Cl/H2O was much lower than that for LiNO3/H2O with the same absorption ability. LiNO3/[BMIM]Cl/H2O has a great potential as an alternative working pair.
