Abstract
In the work with the help of a static method with a membrane zero-manometer, the liquid- vapor balance in the system “dimethylzinc – dimethyl telluride” in the temperature range 270– 360 K with the content of dimethylzinc as 50.00 and 70.32 % mol. The total vapor pressure was measured for both saturated and unsaturated vapors for different samples. It was found that these solutions are not azeotropic. Using the equation of state PV = nRT, according to the thermal expansion of unsaturated vapor, the average molecular weight was calculated for mixtures “dimethylzinc – dimethyltelluride” mentioned compositions. The results of this calculation indicate the absence of significant association between molecules of the solution components in the gas phase.
