The Reflux

This common procedure consists of mixing your reagents with a solvent, boiling the solvent, condensing the vapors, and returning them back to the flask. Observe these rules.



1. The flask should be big enough to hold both the reagents and the solvent without being more than half full.
2. Place the condenser upright on flask and clamp.
3. Adjust your heat source so that the vapors travel no further than halfway up the condenser. Add another condenser if your formula requires a specific temperature and you experience vapor travel higher than halfway at that temperature. Also use drying tube with anhydrousreagents.
