The separation technique used to separate mixtures that contain components with similar boiling points is called distillation.

Distillation is a physical separation process that takes advantage of the differences in boiling points between the components in a mixture. It is based on the principle that when a mixture is heated, the component with the lower boiling point will vaporize first, while the component with the higher boiling point will remain as a liquid.

The process of distillation involves two main steps: vaporization and condensation. First, the mixture is heated in a distillation flask until it reaches its boiling point. As the mixture is heated, the component with the lower boiling point will vaporize and rise up through the distillation column or tube. This vapor contains mainly the low boiling point component.

The vapor then enters a condenser, which is a cool environment that causes the vapor to cool down and condense back into a liquid. The condensed liquid is collected in a separate receiving flask. The higher boiling point component, which did not vaporize, remains in the original flask.

By repeating this process, the separation of the components becomes more efficient. Each time the mixture is heated and vaporized, the concentration of the low boiling point component in the vapor increases. Meanwhile, the high boiling point component remains in the flask and its concentration gradually decreases.

The separated components are typically collected as two distinct liquids, each with a higher purity compared to the original mixture. The efficiency of the separation depends on the difference in boiling points between the components. The greater the difference, the more efficient the separation will be.

Distillation is commonly used in various industries, such as in the production of alcoholic beverages, purification of water, petroleum refining, and pharmaceutical manufacturing. It is an essential technique in chemical laboratories for separating mixtures and obtaining pure substances.
