中文摘要 | 本論文探討以苯胺爲中和劑以分離沸點相近的間氯酚及對氯酚混和物的可能性。本論文以固體消失法建立苯胺、間氯酚及對氯酚三化合物間的雙成分及三成分混合物的固液平衡相圖。由相圖可得間氯酚+對氯酚雙成混和物在間氯酚摩爾分率0.52處有一共熔點在276.0K。苯胺+間氯酚混和物則在苯胺摩爾分率0.22及0.85處有共熔點278.7K及257.2K,並在苯胺摩爾分率0.5處有一合熔點291.0K。而苯胺+對氯酚混和物在苯胺摩爾分率0.28及.087處有共熔點286.2K及259.2K。而上兩個混和物在苯胺摩爾分率0.5處有一合熔點300.0K。而以固定間氯酚對對氯酚組成比的三成分混和物的固液相圖顯示在苯胺0.5處有一合熔點。 由實驗得到數據,本文以Ott及Goates的經驗式關聯決定其關聯參數。關聯結果其溫度平均絕對誤差均小於1.0K而只有一個例外。因此此關連式可以用於預估本實驗之點。 由實驗數據與三成分混和物標示合熔點與共熔點之相圖,本研究提出三個觀念性以苯胺爲中和劑分離間氯酚與對氯酚混和物的程序。 |
英文摘要 | The experimental solid-liquid equilibrium data of ternary mixtures consisting of m-chlorophenol, p-chlorophenol, and aniline, and those of the constituent binary pairs were determined using the solid-disappearance method. The isomer mixture consisting of m-chlorophenol + p-chlorophenol exhibits one eutectic point at 276.0 K with 0.52 mole percentage of m-chlorophenol. The binary mixture of aniline + m-chlorophenol exhibits two eutectic points, 278.7 K and 257.2 K, at aniline compositions of 0.22 and 0.85, respectively , and one congruent point at aniline mole fraction of 0.5. And another pair of aniline + p-chlorophenol also exhibits two eutectic points, 286.2 K and 259.2 K, at aniline compositions of 0.28 and 0.87, respectively , and one congruent point at aniline mole fraction of 0.5. Ternary mixtures with designated mole ratios of m-chlorophenol to p-chlorophenol exhibit two eutectic points and one congruent point also at aniline mole fraction of 0.5. All the experimental SLE data were fitted by the empirical equation of Ott and Goates with an optimization technique. The results showed the equation of Ott and Goates represents the experimental data fairly well with the average absolute deviation of temperature less than 1.0 K. All the parameters were given and can be used for interpolation purpose. Based on the experimental data and the ternary phase diagram showing all the eutectic and congruent points, three conceptual feasible processes using aniline as an adductive agent for separating m-chlorophenol from p-chlorophenol are proposed. |
