Fractional Distillation vs. Simple Distillation: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 20, 2023
Fractional distillation separates mixtures into multiple components based on boiling points, while simple distillation separates a solvent from a solution in one step.

Key Differences

Fractional distillation and simple distillation are both separation techniques utilized in laboratories and industries. Fractional distillation is a method wherein a mixture is separated into its multiple components based on their different boiling points. This method often employs a fractionating column that allows for multiple vaporization-condensation cycles, enhancing separation.

Simple distillation, on the other hand, is a more straightforward process typically used to separate a solvent from a solution or two liquids with substantially different boiling points. In simple distillation, the mixture is heated, and the component with the lowest boiling point evaporates first, condensing and being collected separately.

One of the key differences between fractional distillation and simple distillation lies in the precision of separation. Fractional distillation can differentiate between substances with very close boiling points, thanks to the fractionating column. This makes it ideal for separating complex mixtures, such as petroleum into various fractions.

Simple distillation lacks this precision, making it less suitable for separating components with close boiling points. Instead, it's more commonly used for purifying a single component, like obtaining distilled water from tap water. While both methods exploit the principle of varying boiling points, their applications and intricacies differ significantly.

The equipment used for each process also distinguishes them. Fractional distillation requires a fractionating column, which provides surface area for repeated vaporization and condensation, whereas simple distillation employs a simpler setup without this column.
