| Abstract: | The experiment of extraction of caffeine from tea is very professional which is time-consuming and the extracter used is poisonous. To stimulate students' interest in learning, reform teaching content and enhance students' ability, the paper studies the conditions of solution, the selection of extracters and heat strength control during the condensing of filtrate and sublimation following to improve them in terms of the principle of safety, economy, high-resolution and enviroment-conserving. The improved experiment has been applied to experimental teaching of fundamental chemistry and obtained perferable effect. |
