摘要：

A method for calculating the self-diffusion coefficients of molecules in multicomponent liquid mixtures with arbitrary compositions was suggested. The method was based on the Stokes-Einstein equation and the assumption of the volume-additive character of the numerical multiplier in this equation. The self-diffusion coefficients of molecules of separate components in the individual state at infinite dilution in each of mixture components and dynamic viscosities of separate individual components and a mixture of a given composition are necessary and were used for calculations.
