Abstract:This paper deals with the teaching reform of organic chemistry experiment .Four heteropoly acids of Keggin type have been employed as the catalysts which replacing sulphuric acid to prepare ethyl acetate.The effect on the product quantity of catalyst type,quantity and reacting time has been studied.The result shows that heteropoly acids are excellent and ideal catalysts for students experiment because of the less quantity,shorter reacting time and of no corrosiveness,no danger for students and no pollution for environment.
Keywords:Heteropoly acid  Catalyst  Ehtyl acetate  Preparation
