Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial [1] and laboratory [2] distillations. It is also used in chemistry to supply energy to reactions over a long period of time.
3 lip 2022 · In chemistry, reflux involves heating a chemical reaction for a specific amount of time while cooling it using a condenser. The condensation of the vapors above the reaction returns to the flask. The temperature of the reaction remains constant. What types of reactants can be used in reflux experiment? Apparatus for reflux in chemistry.

22 kwi 2024 · To heat a reaction safely in the necessary time, a technique called reflux is used (see Figure). Assembly scheme. A round-bottomed flask with a ground glass joint is placed on a heat source (hot plate or heating mantle). The flask is fixed to the metal rod with a clamp and clamp holder.
Reflux is a commonly used method of heating a reaction. When setting up apparatus for reflux, you need to clamp glassware securely, and use an appropriate heat source such as a stirrer hotplate. The principle of the reflux operation is to safely provide a controlled amount of heat to the reaction, while ensuring that the solvent does not boil off.
