Equilibrium Boiling Point Apparatus
Main characteristics of the bench
Equilibrium Boiling Point Apparatus
- Boiling point cell made of borosilicate glass
Principal and Operation:
A liquid (X) is heated up to its boiling point in a micro-boiler; the producing vapours (Y) are in equilibrium with the liquid. At atmospheric pressure, a total condenser flows back the hot condensates into the boiler: The equilibrium between the boiling liquid and its vapour is perfect.
The boiling point cell is equivalent to one perfect theoretical stage; when the liquid – vapour equilibrium is maintained sample can be taken from the liquid and the gas phases using micro-syringes.
Teaching objectives
- Determination of the equilibrium curves at atmospheric pressure.
