Abstract: 
Using a semi-empirical model, the vapor-liquid equilibrium is described in the dimethylzinc-dimethyl telluride system: the activity coefficients of the solution components and the partial-molar heats of mixing at infinite dilution are calculated. The primary data for the application of the semi-empirical model were obtained by us from measuring the temperature dependence of the saturated vapor pressure of highly pure samples of dimethylzinc, dimethyl telluride and their solutions.
