Zusammenfassung
Precise vapor pressure data for pure acetonitrile and (LiBr + acetonitrile) are given for temperatures ranging from T = (298.15 to 343.15) K. The molality range is from m = (0.0579 to 0.8298) mol . kg(-1). The osmotic coefficients are calculated by taking into account the second virial coefficient of acetonitrile.

Precise vapor pressure data for pure acetonitrile and (LiBr + acetonitrile) are given for temperatures ranging from T = (298.15 to 343.15) K. The molality range is from m = (0.0579 to 0.8298) mol . kg(-1). The osmotic coefficients are calculated by taking into account the second virial coefficient of acetonitrile. The parameters of the extended Pitzer ion interaction model of Archer and the mole fraction-based thermodynamic model of Clegg-Pitzer are evaluated. These models accurately reproduce the available osmotic coefficients. The parameters of the extended Pitzer ion interaction model of Archer are used to calculate the mean molal activity coefficients.
