The isothermal vapor-liquid equilibrium data for the binary systems of cyclopentene (1)+cyclopentyl methyl ether (2) were measured at 313.15, 323.15, 333.15, 343.15 and 353.15 K using a dynamic-type equilibrium apparatus and online gas chromatography analysis. For all the measured VLE data consistency tests were performed for the verification of data using Barker’s method and the ASPEN PLUS Area Test method. All the resulting average absolute values of residuals [δ ln (γ₁/γ₂)] for Barker’s method and D values for the ASPEN PLUS area test method were comparatively small. So, the VLE data reported in this study are considered to be acceptable. This binary system shows negative deviation from Raoult’s law and does not exhibit azeotropic behavior at whole temperature ranges studied here. The measured data were correlated with the P-R EoS using the Wong-Sandler mixing rule. The overall average relative deviation of pressure (ARD-P (%)) between experimental and calculated values was 0.078% and that of vapor phase compositions (ARD-y (%)) was 0.452%.
