Vapor pressure of heat transfer fluids of absorption refrigeration machines and heat pumps: Binary solutions of lithium nitrate with methanol

Vapor pressure p of LiNO3 + CH3OH solutions at T = (298.15 to 323.15) K was reported, osmotic ϕ and activity coefficients γ; and activity of solvent as have been evaluated. The experiments were carried out in molality range m = (0.18032 to 5.2369) mol · kg−1. The Antoine equation was used for the empiric description of experimental vapor pressure results. The Pitzer-Mayorga model with inclusion of Archer's ionic strength dependence of the third virial coefficient was used for the description of calculated osmotic coefficients. The parameters of Archer extended Pitzer model were used for evaluation of activity coefficients.
