From the preceding information, a graph of temperature versus mass % distilled can be produced. This distillation curve corresponds to a laboratory technique, which is defined at 15/5 (15 theoretical plate column, 5:1 reflux ratio) or TBP (true boiling point).

The liquid distils from the flask inside the oven to a cold bulb outside the oven. Since the distillation path is very short the length of a ground-glass joint losses are minimized. The use of several bulbs as receiver flasks allows a small volume of mixture to be fractionated by varying the temperature in the oven.

Distillation is a physical process that extracts desirable pure substances from a mixture source by evaporating the substance, then condensing it in a separate container. Uses of distillation include common products such as gasoline and other fuels, purified water, whiskey and paraffin wax.

4) When a careful distillation is performed on a mixture of liquids with widely different boiling points, the head temperature rises and plateaus, then drops before rising again during the distillation. Explain what is happening during each of these phases. Answer: The head
