结合化工专业本科有机合成实验教学，设计了以负载型WO3/Al2 O3为催化剂的乙酸乙酯合成综合实验，在实验中采用气相色谱检测乙酸乙酯的产率，考察了钨的负载量对反应的影响，克服了浓硫酸为催化剂对设备腐蚀严重、产生大量废酸，尤其是催化剂和产物分离等问题。

Combining the experiment in organic chemistry ,the preparation of WO3/Al2 O3 and its catalytic application in synthesis ethyl acetate were designed for chemistry and chemical engineering major students . The GC was used in characterizing the yield of ethyl acetate ,and the influence of loading of W on the reaction was also discussed .The catalyst WO3/Al2 O3 hurdles the reason of seriously corrosivity ,a mass of waste acid , and separation of catalysts and production .
