Vapour-liquid equilibrium (VLE) at P = 50.0 kPa and 100.0 kPa have been determined for binary system (ZE-2-methyl-2-butenenitrile + 2-methyl-3-butenonitrile). To analyze binary data, the vapor pressures of ZE-2-methyl-2-butenenitrile and 2-methyl-3-butenonitrile were determined and the experimental values were correlated by an Antoine-type equation. The predicted results of vapor pressures by Antoine equation showed that the average relative deviation from experimental values was 1.964% and 0.907% for ZE-2-methyl-2-butenenitrile and 2-methyl-3-butenonitrile, respectively. Thermodynamic consistency tests were performed for all VLE data using point test, area test and direct test and all data passed the three tests. VLE binary data were all calculated by activity coefficients correlated using Wilson and NRTL models. The model parameters were obtained and all models represent the experimental values quite well.
