Zusammenfassung
Precise vapor pressure data for LiBr solutions in ethanol are given for temperatures ranging from 298.15 to 348.15 K. The molality range investigated is from 0.0705 to 3.4451 mol-kg(-1). Osmotic coefficients are calculated by taking into account the second virial coefficient of ethanol.

Precise vapor pressure data for LiBr solutions in ethanol are given for temperatures ranging from 298.15 to 348.15 K. The molality range investigated is from 0.0705 to 3.4451 mol-kg(-1). Osmotic coefficients are calculated by taking into account the second virial coefficient of ethanol. The parameters of the extended Pitzer ion-interaction model of Archer, the MSA-NRTL model, and the chemical model of Barthel are evaluated and discussed. The parameters of the extended Pitzer ion-interaction model of Archer are used to calculate the mean molal activity coefficients. Osmotic and activity coefficients both decrease with increasing temperature in this temperature range.
