在傳統化工製程中，反應與分離程序是獨立操作，而反應蒸餾是將兩種操作合併於同一裝置，可以提高轉化率，減少能源損耗，降低操作成本。本研究目的除了探討反應蒸餾生產丙烯酸乙酯之可行性，另外因系統分離依賴汽液平衡及液液平衡，熱力學模式參數對整個程序影響顯著，故將使用兩組熱力學物性資料(A, B)對系統做進一步分析，並比較其結果。首先觀察各成份相圖並探討蒸餾殘餘曲線，找出系統存在的共沸點並了解程序可能之蒸餾路徑，作為製程設計之重要參考；接著從可行性分析結果提出兩個設計程序，藉由操作變數的改變探討最佳操作條件，再利用開環動態響應，了解干擾對程序之影響，發現系統存在高度非線性行為，提供研究控制策略參考。最後比較兩組熱力學物性資料對不同程序造成的影響，得知熱力學參數掌控整個程序之設計，因此審慎選用熱力學參數對反應蒸餾塔進行模擬時，極為重要不容忽視。

In the conventional process design, reaction and separation are operated individually. Reactive distillation, the combined simultaneous operation of chemical reaction and distillation, is a commercially proven alternative to the conventional process especially to carry out the liquid phase chemical reactions. Compared to the conventional techniques, it offers several advantages: increased the conversion, decreased the consumption of resources and lowered the cost of operation. The purpose of this study is not only investigating the feasibility of the production of ethyl acrlylate with reactive distillation, but also analyzing the system based on two sets of thermodynamic physical properties (A, B) and comparing their results. Due to the fact that the separation operation depends on vapor-liquid equilibrium and liquid-liquid equilibrium, thermodynamic parameters play an important role on the process design. At first, we observe the phase diagrams among every component composition and study the feasibility of separation by means of the residual curve maps. Then we find out that there exist azeotropes in the system and the possible pathways of distillation in the system. Next, we have designed two processes on base of the result of feasibility. Having investigated the variation of the system manipulated variables, we find out the possibly best conditions. Furthermore we study the dynamic responses when the designed process encounters disturbance. The reactive distillation system displays the higher nonlinear properties. This result can be considered by the studiers in the control plan in the future. At last, the two thermodynamic physical properties are compared and discussed the influences on process design.
