在常压下，用回流吸附方法制备了活性炭固载对甲苯磺酸（ＴｓｏＨ／Ｃ）催化剂，采用反滴定法测定固载量。通过正文实验，找到催化剂最佳固载量为（４８±０．５）％，最佳活化温度为１２０℃。首次提出用固载量为（４８±０．５）％的ＴｓＯＨ／Ｃ催化摩尔比为１．５：１的乙酸与乙醇的酯化反应，在液相温度达到（１０８±２）℃时，可以９２％的收率连续制备出乙酸乙酯。其折光率及红外光谱与文献值一致。该酯化工艺及非固载型对甲苯磺酸工艺相比，具有催化剂用量少，使用寿命长，酯收卒高，反应后处理工序简单，不污染环境，不腐蚀设备，酯化反应既可间歇操作又可连续操作等优点．
Under normal pressure, the activated carbon supported TsoH / C catalyst was prepared by reflux adsorption method, and the solid support was measured by back titration method. Through the text experiment, the best catalyst loading was found to be (48 ± 0.5)%, and the optimum activation temperature was 120 ℃. It was first proposed that the esterification reaction of acetic acid and ethanol with a molar ratio of 1.5: 1 of TsOH / C with a loading of (48 ± 0.5)% was achieved at a liquid phase temperature of (108 ± 2) ℃. Ethyl acetate can be continuously prepared in 92% yield. The refractive index and infrared spectra consistent with the literature. Compared with the non-supported p-toluenesulfonic acid process, the esterification process has the advantages of less catalyst usage, long service life, high ester yield, simple post-reaction treatment process, no pollution to the environment and no equipment corrosion. The esterification reaction Intermittent operation can be continuous operation and so on.
