AbstractThe reaction for hydrogenation of benzene has been paid much attention as the demand for synthesis of nylon rapid developa. Usually, byproducts of cyclohexane and unreacted benzene unavoidably exist in the production of cyclohexene through the hydrogenation of benzene route. To obtain cyclohexene with high purity, extractive distillation is used to separate cyclohexene mixture. However, the process simulation for extractive distillation is necessary for industry design and production, which requires the relevant vapor liquid equilibrium (VLE) data to simulate accurately. The VLE data for the binary systems of extractant N,N-dimethylacetamide (DMAC) with cyclohexene, cyclohexane, and benzene at atmospheric pressure was measured using a PH-I-type VLE kettle. In addition, a thermodynamic consistency check has been done on the obtained data, indicating that the experimental data satisfy the examination of the thermodynamic consistencies. Moreover, the results are significantly close when NRTL and Wilson equations are used to correlate with data. The maximum deviation for the average vapor composition and the average temperature composition are 0.0095 K and 1.12 K, respectively, which is satisfactory for the separation engineering design requirement. The results could provide basic data for practical application.
