Background For organic synthesis. the mixture is often acquired. which might include substrates products, catalysts by-products In order to get the single and pure compound further purification Is necessary It was known that many different methods have been developed for purification This experiment is to learn one of the most general measures in organic laboratories. It is the adsorption column chromatography, which is suitable for the separation of solid-solid, liquid-liquid, solid-liquid mixturesBackground For organic synthesis, the mixture is often acquired, which might include substrates, products, catalysts, by-products.
