Many reactions are slow processes and require prolonged heating. In order to avoid loss of solvent a reflux system is necessary. In the reflux process the solvent boils but is then condensed and returned to the reactants.

There are many potential problems when using an incorrectly setup reflux system. Try setting up a reflux using the simulation below and you will be better prepared in the laboratory:
