本研究採用靜態式總壓法量測n-nonane + n-hexane、n-nonane + n-octane、n-nonane + methylcyclopentane、n-nonane + methylcyclohexane、n-nonane + 1,3,5-trimethylbenzene、methylcyclohexane + n-octane、methylcyclohexane + methylcyclopentane、methylcyclohexane + 1,3,5-trimethylbenzene共8組雙成分混合物系統之恆溫下汽液相平衡數據,溫度分別在363.15 K、393.15 K、433.15 K、473.15 K下,包含莫耳分率為0.2、0.4、0.6、0.8共4種組成,每組系統共有16個恆溫汽液相平衡數據。實驗結果顯示在量測溫度範圍內皆沒有共沸物產生。本研究亦從公開文獻中取得n-hexane + n-octane、n-hexane + benzene、n-hexane + n-heptane共3組雙成分混合物系統之汽液相平衡數據。
本研究使用Aspen Plus針對上述之汽液相平衡數據均以NRTL-HOC模式進行關聯,並求得每一雙成分系統的最適化參數值,結果顯示NRTL-HOC模式可準確地描述此11組系統之汽液相平衡行為。
In the present study, the static total pressure method was used to measure the isothermal vapor-liquid equilibrium (VLE) data for eight binary systems of n-nonane + n-hexane, n-nonane + n-octane, n-nonane + methylcyclopentane, n-nonane + methylcyclohexane, n-nonane + 1,3,5-trimethylbenzene, methylcyclohexane + n-octane, methylcyclohexane + methylcyclopentane, methylcyclohexane + 1,3,5-trimethylbenzene at 363.15 K, 393.15 K, 433.15 K and 473.15 K, including mole fraction of 0.2, 0.4, 0.6, 0.8. There are sixteen isothermal VLE data points for each system. The experimental results show that no azeotrope is formed over the entire temperature range. Additionally, the VLE data of three binary systems of n-hexane + n-octane, n-hexane + benzene, n-hexane + n-heptane are also obtained from open literature.
In this study, the Aspen Plus is used to correlate the above VLE data with the NRTL-HOC model and determined the optimum values of the NRTL model parameters for each binary system. The results show that the NRTL-HOC model can accurately describe the VLE behavior of these eleven systems.
