本研究使用填充床反應器(PBR)探討乙酸乙酯合成的非均相反應動力與吸附行為，本實驗使用酸性陽離子交換樹脂Amberlyst 35 為觸媒。乙酸乙酯合成反應的實驗操作於323.15 K到348.15 K之間，此外，本研究亦探討進料醇/酸莫耳比以及觸媒的質傳阻力效應。實驗結果顯示酯化反應中，乙酸乙酯之平衡轉化率幾乎與溫度無關，但隨醇/酸進料莫耳比的增加而大幅提高。吸附平衡實驗的結果顯示各成分吸附效應之強弱依序為水>乙酸>乙醇>乙酸乙酯。動力數據分別以理想擬均相動力模式，非理想擬均相模式，Langmuir-Hinshelwood-Hougen-Waston (LHHW)模式，Eley-Rideal (ER)模式，modified LHHW模式與modified ER模式關聯，並求得最適化的動力參數值，關聯的結果顯示modified LHHW模式為最適合描述乙酸乙酯合成反應的非均相催化動力行為。

The heterogeneous kinetics and adsorption behavior were investigated with a packed-bed reactor for the synthesis of ethyl acetate over an acidic cation-exchange resin, Amberlyst 35. The esterification was conducted at temperatures from 323.15 K to 348.15 K. Additionally, the effects of molar ratios of alcohol to acid in the feed stream (θB0) and the mass transfer resistance on the catalytic reaction were also studied. The equilibrium conversion of acetic acid was found to be almost independent of temperature but markedly increased with increasing the feed composition θB0. The relative adsorption strengths for the reacting species were determined by adsorption experiments. The results indicated that the magnitude of adsorption strengths followed the order of water > acetic acid > ethanol > ethyl acetate. The kinetic data were correlated with the ideal-quasi- homogeneous, the non- ideal-quasi-homogeneous, the Langmuir-Hinshelwood-Hougen-Waston (LHHW), the Eley-Rideal (ER) models, the modified LHHW (M-LHHW), and the modified ER (M-ER). The optimal values of the kinetic parameters were determined from the data fitting. The M-LHHW model yielded the best presentation for the kinetic behavior of heterogeneous catalytic synthesis of ethyl acetate.
