Gas-liquid phase equilibrium data of methyl chloride-n-hexane binary system was measured by phase equilibrium apparatus in which liquid circulates. Experimental data was regressed and Binary parameter of methyl chloride and n-hexane kij was calculated by SRK state equation, which is 0.05. It was found that liquid phase constitute of methyl chloride in n-hexane decreases with the increase of temperature, but increases with the increase of pressure. The average standard deviation of CH3Cl gas constitute was 1.0764% and the average standard deviation of pressure was 0.9854%, which explain SRK state equation is accurate in regressing gas-liquid phase equilibrium data. Basing on it, gas-liquid phase equilibrium data of methyl chloride-n-hexane binary system in all concentration range were calculated. p-x, y phase graph at 25, 30, 40, 50°C was obtained.
