摘　　要：Liquid phase synthesis of one of the important fuel oxygenate, ethyl tert-butyl ether （ETBE）, from etha-nol and tert-butyl alcohol （TBA） has been studied in catalytic distillation column （CDC） using ion exchange resin catalyst CT-145H. A packed CDC of 1.2 m height and 50 mm diameter with indigenously developed reactive sec-tion packing was used to generate experimental data. Effect of different key variables on product purity in distillate, was investigated to find the optimum operating conditions for ETBE synthesis. The optimum conditions for 0.2 kg·s-1 of ethanol feed were found：reboiler duty of 375 W, molar feed ratio of 1︰1.3 of reactants, and reflux ratio of 7. Concentration profiles for each component along each column section at optimum conditions were also drawn. Neither output nor input multiplicity was observed at experimental conditions.重要燃料之一的液体阶段合成氧化，乙醇 tert 丁基醚(ETBE ) ，从乙醇和 tert 丁基，酒精(TBA ) 用离子交换树脂催化剂 CT-145H 在催化蒸馏列(CDC ) 被学习了。有该土地所固有的 1.2 m 高度和 50 公里直径的包装 CDC 开发了反应的节收拾行李被用来产生试验性的数据。在精华的产品纯净上的不同关键变量的效果，被调查发现最佳为 ETBE 操作条件合成。为 0.2 kg
