A number of different mixtures of phenol and water are prepared
and heated until complete miscibility is achieved. As the mixtures
cool, two-phase systems form at certain temperatures which are
recognisable by the appearance of turbidity. Plotting separation
temperatures against compositions of the mixtures gives the
- Good and reproducible results due to temperature control in the experiment.
- Plot the separation curve of the phenol / water binary system
and prepare a temperature / mass fraction diagram.
- Determine the critical separation point.
