本研究經由蒸餾程序使用乙醇與乙醛以及酸性陽離子交換樹酯觸媒（Amberlyst®15）生產乙縮醛。程序設計中主要設備為一座連續攪拌反應器，兩座蒸餾塔以及兩座分相槽。經由反應性殘餘曲線分析，發現系統中具有共沸點轉移現象以及發現新的蒸餾邊界。乙縮醛與水的混合物可經由分相槽整合蒸餾塔程序將其分離。連續攪拌反應器操作溫度以及分相槽操作溫度對於程序影響重大，因此在動態設計上，於該設備之前架設熱交換器，減輕其熱負荷。本研究生產乙縮醛程序中，乙醛轉化率幾近100%，為相當高的轉化率。

This work presents the development of a novel process for the production of diethylacetal from the reaction between ethanol and acetaldehyde catalyzed by the acid resin Amberlyst ®15 using distillation technology. The main equipments in the process design are one continuous-stirred tank reactors, two distillation columns and two decanters. By way of reactive residual curve map the system exhibits azeotropic transfer phenomenon and a new distillation boundary was discovered. Diethylacetal and water mixture can be separated by using distillation columns in conjunction with decanters. The operating temperature of the CSTR and decanters influence the system greatly, thus, heat exchangers are added to reduce the heat duty. In this work, Simulated results show that high acetal purities can be achieved for 100% acetaldehyde conversion.
