![]() The apparatus is assembled as in the diagram. For this reason, ethanol cannot be completely purified by direct fractional distillation of ethanol-water mixtures. In this example, a mixture of 96% ethanol and 4% water boils at 78.2 ☌ (172.8 ☏) the mixture is more volatile than pure ethanol. Some mixtures form azeotropes, where the mixture boils at a lower temperature than either component. So, by heating the mixture, the most volatile component (ethanol) will concentrate to a greater degree in the vapor leaving the liquid. It is used to refine crude oil.įractional distillation in a laboratory makes use of common laboratory glassware and apparatuses, typically including a Bunsen burner, a round-bottomed flask and a condenser, as well as the single-purpose fractionating column.Īs an example, consider the distillation of a mixture of water and ethanol. If the difference in boiling points is greater than 25 ☌, a simple distillation is typically used. Generally the component parts have boiling points that differ by less than 25 ☌ (45 ☏) from each other under a pressure of one atmosphere. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize.
