Abstract
Precise vapor pressure data for LiBr solns. in MeOH are given for temps. ranging from 298.15-333.15 K. The molality range is from 0.0411-6.8675 mol-kg-1. Osmotic coeffs. were calcd. by taking into account the 2nd virial coeff. of MeOH. The parameters of the Pitzer-Mayorga model, the Archer extension of the Pitzer-Mayorga model, the mole-fraction-based thermodn. model of Clegg-Pitzer, and the recently developed MSA-NRTL model are evaluated, along with the corresponding std. deviation. These equations were used to calc. activity coeffs. of LiBr in MeOH solns.
