摘要：

The specific conductance of LiAsF6 solutions in three acetonitrile propylene carbonate (AN + PC) mixtures and in the pure components has been measured at 25-degrees-C. The results for dilute solutions have been analysed using five conductance equations. The limiting molar conductivity LAMBDA(o), the association constant of ion pairs K(A), the distance parameter R, the dissociation degree gamma, and the mean activity coefficient f +/- have been calculated. The vapour pressure isotherms of AN + PC mixtures P were measured at 25 and 40-degrees-C. Activity coefficients of the second and the first components f2 and f1, respectively, the excess Gibbs energy G(E), and the excess enthalpy H(E) (the heat of mixing), have been evaluated from the experimental data.
