Fractional distillation: Is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compound will evaporate.
Aim: To show the use of fractional distillation for the separation of liquid - liquid mixtures in which the boiling points of the components are similar.
Materials:
- Heater
- Thermometer
- Water inlet-outlet
- Distilling Flask,
- Beaker
- 4 Test Tube
- Tripod
- Acetone-Water-Alcohol mixture
Procedure:
- Start heating the homogenous mixture of acetone, alcohol and water. (at 30 degree)
- Every 30 seconds take the temp. reading.
- When the temp. starts almost constant collect the condensed liquid, save it in a test tube. (around 50o)
- When the temp. begins to raise again taking temp. reading every 30 seconds. Keep heating the mixture.
- When it gets constant again collect the liquid and keep it another test tube. (around 70o)
- Then increase the degree to 6o. And collect the consented liquid around 80o .
- Then collect the last liquid around 95o.
