Description
Study of liquid-vapour equilibria under a vaccuum using a bench top ebulliometer
Principals:
- Theoretical study of binary mixtures
- Ideal miscible mixtures: Dalton’s equation, Raoult’s equation
- Non-ideal miscible mixtures (deviation, volatility, azeotropic mixtures)
- Partially-miscible and non-miscible mixtures
- Experimental study of binary mixtures
- At atmospheric pressure and under vacuum
- Liquid-vapor phase diagram
- Boiling and condensation isobaric phase diagram.
- Application to rectification: calculating the number of theoretical plates
Proposed Experiments:
- Isobaric study of a binary mixture:
- Sequential or semi-continuous method.
- Analyse the composition of the liquid and vapour phases.
- Apply the results:
- Plot the liquid-vapour equilibrium diagram at various pressures
- Plot the boiling and condensation isobaric phase diagram at various pressures.
- Compare the diagrams.
- Determine the number of theoretical plates by the McCabe-Thiele method.
- Determine the relative and actual volatility.
