Conclusions
-
1.
The distribution coefficient of microimpurities between the liquid and vapor was determined by the method of Rayleigh distillation and a static method in solutions of ethylene, diborane, germane, phosphine, arsine, and benzene in silane. In all the systems considered, a positive deviation from Raoult's law is observed.
-
2.
The distribution coefficients and thermodynamic activity of the impurities indicated above, as well as n-butane and diethyl ether in silane, were calculated by a statistical method. The calculated and experimental data are in good agreement.
