Vapor-pressure measurements on (water+lithium chloride+lithium nitrate) at temperatures from 274.15 K to 463.15 K

Thermodynamic study of the system (LiCl+LiNO3+H2O)

“…It is shown in figure 8 that the parameters S ij and T ij represent the experimental solubility isotherms quite satisfactorily. However, the water activities calculated with the equations (3), (6), (7), (11) and (12) deviate more significantly from the experimental values [2] than those calculated by using equations (3), (6), (7) (see table 6). The comparison shows that the BET version modified by Abraham and Abraham [15] is more suitable to represent the experimental data of the system (LiCl + LiNO 3 + H 2 O) than that modified by Clegg and Simonson [16].…”

“…Physical and thermodynamic properties of the ternary system (LiCl + LiNO 3 + H 2 O), including solubility, vapour pressure, and viscosity, have been extensively investigated as possible working fluids in absorption refrigeration and heat pump systems [1][2][3]. However, the data obtained by experimental technique are not always reliable.…”

Measurements of Vapor Pressures of Aqueous Solutions in the NaCl–KCl–H2O System from 493.15 to 693.25 K in a Fused Silica Capillary High-Pressure Optical Cell

“…Most of the published correlation models for the vapor pressures of aqueous electrolyte solutions emphasized solutions containing only one electrolyte, such as the model of Pitzer et al, which extended the Debye–Hückel equation, the model of Patil et al, and the modified Antoine equation of Sacchetto et al Even though some models were proposed for solutions that contained mixed electrolytes, ,− most of these models were applicable only at temperatures below 373 K due to the lack of the experimental data at higher temperatures that are needed to formulate and verify these models.…”

Vapor Pressures of the Ethylamine + Water + Lithium Bromide System and Ethylamine + Water + Lithium Nitrate System

“…Apparatus and Procedure. The experimental apparatus used for vapor pressure measurements has been reported in our previous papers Uemura, 1989, 1990;Iyoki et al, , 1993. It consists primarily of a sample vessel with a volume of about 500 cm 3 , a constant temperature bath, a heater, a temperature controller, and a U-tube manometer.…”
