Fractional Distillation Process To Separate Organic Liquids Assignment Paper

Fractional Distillation Process To Separate Organic Liquids: Distillation is a very useful method of purifiying liquids. Simple distillation is used when a pure solvent is required to be obtained from the solution. This is usually water. On the other hand, fractional distilation is basically used for the separation of a mixture of two miscible organic liquids having different boiling points. A common example of two liquids that mix with each other are ethanol and water. Another example is petrol and paraffin.Fractional Distillation Process To Separate Organic Liquids Assignment Paper

In this experiment, a mixture of acetone and toluene was provided. Basically, the liquid mixture was boiled to evaporate the liquid that had the lowest boiling point, referred to as the first fraction. The vapour passed up through a fractionating column, which is not used in a simple distillation. As the mixture vaopur passed up the fractionating column, it continually condensed and evaporated.Fractional Distillation Process To Separate Organic Liquids Assignment Paper. This caused it to become increasingly richer in the liquid with the lowest boiling point until the vapour that reached the top consisted almost entirely of the component with the lowest boiling point. The vapour is then cooled in the condenser and so it condensed back to a liquid, which was collected, hence referred to as the distillate. When almost all the liquid with the lowest boiling point was distilled over, the temperature rised rapidly showing that a mixture of both liquids was distilling over. This should be collected in a separate container and discarded. Once the temperature reached the boiling point of the second liquid, the liquid was then distilled into another container.Fractional Distillation Process To Separate Organic Liquids Assignment Paper

This basically explained the process of fractional distillation. However, there is a theory behind all this, because the process of distillation should be related in reference to an ideal liquid mixture where one is more volatile than the other. Regarding the mixture of acetone/toluene provided in this experiment, ideal behaviour was assumed and once the process was carried out, the more volatile liquid was found by finding the boiling point of each component.

It was noted that the more volatile liquid was acetone since this had a lower boiling point. This was discussed further in relation to boiling point-composition graphs.
