dimethylzinc

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.

The thermodynamic parameters were calculated. for the vapor-liquid equilibrium of “dimethylzinc-dimethyl selenide” system using the tensometric data obtained for high-purity dimethylzinc, dimethylselene and their equimolecular solution. For this purpose, the Wilson’s model, whose parameters were calculated by the activity coefficients of components in the azeotrope, were used. The calculation was made using the mathematical package MathCad 14.
