本研究以高溫高壓連續式反應器探討碳酸二乙酯與乙酸苯酯的均相轉酯化反應動力行為，以有機鈦化合物鈦酸四乙酯為本實驗的觸媒，實驗操作於438.15 K ~ 468.15 K之間，壓力介於20 bar~ 30 bar之間，進料乙酸苯酯/碳酸二乙酯莫耳比為6、4及3以及進料碳酸二乙酯/乙酸苯酯莫耳比為6。實驗結果顯示碳酸二乙酯的反應速率隨溫度增加而提高，但在本實驗之溫度範圍內的平衡轉化率差距不大，亦即一轉酯化反應的熱效應不顯著。另外，當進料莫耳比增大時，平衡轉化率有顯著地提高。
本研究分別以兩種理想溶液均相動力模式關聯所量取之動力數據，以求得模式中的動力參數值。關聯的結果顯示，以整體來說動力模式二為最適合描述碳酸二乙酯與乙酸苯酯之轉酯化反應動力行為，其完成量測的系統提供相關製程模擬與設計使用。

The kinetic behavior of homogeneous transesterification of diethyl carbonate with phenyl acetate over an catalyst, titanium ethoxide, was investigated with a continuous tubular reactor. The tranesterification was performed te between
438.15 K to 468.15 K and the molar ratios of feed (phenyl acetate to diethyl carbonate) at 6, 4, 3 and the molar ratios of feed(diethyl carbonate to phenyl acetate) at 6, respectively. The reaction rate was found increase with increasing temperature, but the equilibrium conversions of diethyl carbonate were close over the entire range of experimental conditions. It means that the heat effect is minor. In addition, the equilibrium conversions of diethyl carbonate was found increase obviously with increasing molar ratios of feed.
The kinetic data were correlated with two different ideal solution quasi-homogeneous kinetic models. The model parameters were determined by fitting the kinetic data to these models. Generally, the second model yielded better representation for kinetic behavior of transesterification of diethyl carbonate with phenyl acetate. This model can be applied to the process simulation and process design.
