Reflux in chemical reaction
WebBig Chemical Encyclopedia. REFLUX. In distillation processes in which a fractionating column is used, the term reflux refers to the liquid that has condensed from the rising … Web4. Heat the reaction mixture gently with a Bunsen burner or a heating mantle. Indirect heating (heating a beaker of water below the pear-shaped flask) is a safe method. If the organic product needs distilling to prevent further reaction then non-reflux heating is used. In his case, quick fit distillation apparatus may be used during synthesis.
