ABSTRACT
Vapor pressure p of LiBr +CH3OH and LiCl +CH3OH solutions at T = (298.15 323.15)K were reported, osmotic, activity coefficients (o, a) and the activity of the solvent as have been evaluated. The experiments were carried out for LiBr +CH3OH solutions in the molality range m= (0.22046 11.51477) mol kg.1 and for LiCl +CH3OH solutions in the molality range m= (0.34002 6.17615) mol kg.1. The Antoine equation is used for to fit the experimental vapor pressure results and the Pitzer Mayorga model with inclusion of Archer s ionic strength dependence of the third virial coefficient was used for the calculation of osmotic coefficients. The parameters of the Archer extended Pitzer Mayorga model were used for evaluation of activity coefficients.
