Compiled equations for describing the experimental data of the liquid-vapor phase equilibrium in six binary mixtures containing two rare gases or one of them and oxygen or methane. Equations represents the liquid or vapor pressure as a function of temperature and composition. For their compilation improved program was used providing automatic selection of the most significant coefficients of the equation. Standard deviations of the experimental values of the pressure from calculated for different mixtures are equal from 1,8 to 5,3 %. Equations also permits to determine the composition or temperature of phases at given values of other parameters of the phase equilibrium
