| Abstract: | The extraction of caffeine from the tea is a classical organic chemistry experiment in the medical colleges and universities. The common questions were the lower purity and yield of the caffeine. In order to improve the yield and purity of the product, we analyzed the key points of the four experimental procedures in this experiment, and concluded some teaching experiences. |
