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.
