WebMar 2, 2016 · Unlike distillation, the reflux process is used in chemistry to accelerate a specific reaction thermally. This is done by conducting it in a controlled high temperature. 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. A mixture of reactants and solvent is placed in a suitable vessel, such as a round bottom flask. This vessel is connected to a water-cooled condenser, which is typically open to the atmosphere at the top. The reaction vessel is heated in order to boil the reaction mixture; vapours produced from the mixture are condensed by the condenser, and return to the vessel through gravity.
