The solubility, vapor pressure, density, viscosity, and specific heat capacity of LiNO₃/H₂O were measured in this work. The solubilities were measured in ranges of temperature from 277.15 K to 431.15 K. The vapor pressures were measured in ranges of temperature and absorbent mass fraction from 297.65 K to 473.15 K and from 50 % to 70 %. The densities and viscosities were measured in ranges of temperature and absorbent mass fraction from 283.15 K to 413.15 K and from 30 % to 65 %. The specific heat capacities were measured in ranges of temperature and absorbent mass fraction from 303.15 K to 373.15 K and from 30 % to 60 %. Regression equations for solubility, vapor pressure, density, viscosity, and specific heat capacity were obtained by a least-squares method from the experimental data. The average absolute relative deviations of each property between the measured data and the individual calculated value from these regression equations were 0.13 %, 0.14 %, 0.12 %, 0.14 %, and 0.23 %, respectively. This research will be helpful when LiNO₃/H₂O is utilized as a working fluid for the absorption heat pump.
