Volumetric Properties of Aqueous Sodium Chloride Solutions
TLDR
In this article, a semi-empirical equation of the same type found to be effective in describing the thermal properties of NaCl solutions has been used to reproduce the volumetric data from O'°C to 300°C and 1 bar to 1000 bar.Abstract:
Literature data for the volumetric properties of sodium chloride solutions to concentrations of 5.5 molal have been compiled and critically evaluated. A semi‐empirical equation of the same type found to be effective in describing the thermal properties of NaCl solutions has been used to reproduce the volumetric data from O °C to 300 °C and 1 bar to 1000 bar. Tables of values are given for the specific volume, expansivity, and compressibility. Equations also are given for calculating the pressure dependence of the free energy, enthalpy, and heat capacity. These equations can be combined with a treatment of thermal properties to form a complete equation of state for sodium chloride solutions.read more

Determination of the homogenization temperatures and densities of supercritical fluids in the system NaClKClCaCl2H2O using synthetic fluid inclusions
Yi-Gang Zhang,John D. Frantz +1 more
TL;DR: In this paper, the homogenization temperatures of the synthetic fluid inclusions were analyzed by micro-thermometry, and the results of these experiments compare favorably to previously published ones; however, they do not consider solutes containing more than one solute.

The system H2O–NaCl. Part I: Correlation formulae for phase relations in temperature–pressure–composition space from 0 to 1000 °C, 0 to 5000 bar, and 0 to 1 XNaCl
TL;DR: In this article, a set of correlations describing the phase stability relations in the system H 2 O-NaCl is developed, including the vapor pressure of halite and molten NaCl, the NaCl melting curve, the composition of a halite-saturated liquid and vapor, the pressure of vapor+ liquid+halite coexistence, the temperature-pressure and temperature-composition relations for the critical curve, and the compositions of liquid and vapour on the vapor+liquid coexistence surface.
