The density of liquid NaCl and KCl and an estimate of their critical constants together with those of the other alkali halides

Phase behavior of three-component ionic fluids

“…It has been shown experimentally that ionic solutions exhibit liquid-liquid phase coexistence, terminated by a critical point, similar to ordinary (nonionic) fluids [6]. Theoretically, such a demixing transition has been rationalized in terms of an effective attraction between the ions [7,8] which is due to charge screening, first introduced by Debye and Hückel [9].…”

“…Theoretically, such a demixing transition has been rationalized in terms of an effective attraction between the ions [7,8] which is due to charge screening, first introduced by Debye and Hückel [9]. For simple inorganic salts, such as NaCl, this critical point occurs at temperatures above 3000 K [6] and thus precludes precise measurements. More detailed experiments became available with the advent of large organic ions, which show critical points at temperatures of 414 K [10] and, more recently, at 317 K [11].…”

Some Properties of Molten KCl at High Density Studied by MD Simulation

“…The density under ambient pressure measured by them is somewhat higher than that by Kirshenbaum et al [8]. Therefore, the pressure at the molar volume of 52.0 cm 3 mol -1 has a negative value according to the former data, while it is nearly zero if the latter data are taken.…”

Application of Association Model for Solubilities of Alkali Metal Chloride in Water Vapor at High Temperatures and Pressures

“…The values of the Table 1 Antoine constants (Stull, 1947) Kirshenbaum et al (1962) c ω = -log(P o /P C ) T T C = 0 7 . -1.000 (Pitzer, 1955) d Hearn et al (1969) parameters were listed in Table 3.…”
