Importance of refluxing in organic chemistry
Witryna3 cze 2024 · The role of a condenser here is to cool down the generated vapours and convert them back into the liquid form. The liquid component is then sent back to the boiler. So the reflux condenser purpose is to stop the loss of solvent, thereby increasing the reaction time over which the flask can be heated. How is reflux used in a chemical … WitrynaPerforming reactions under reflux is an important technique to understand. Apart from providing a system whereby solvent and volatile reagents are recycled, it also allows …
