DISTILLATION Meaning and
Definition
-
Distillation refers to the process of separating a mixture of liquids or obtaining a desirable component from a liquid by selectively heating it and condensing the vapor that forms. It is a widely used technique in chemistry and industry to purify liquids, extract essential oils from plants, and produce alcoholic beverages.
During distillation, the liquid mixture is heated to its boiling point, causing the more volatile components to vaporize, while the less volatile ones remain in the liquid phase. The vapor generated is then collected and condensed back into a liquid form through cooling, resulting in the desired product.
Distillation exploits the differences in boiling points or volatility of the substances in the mixture. The substances with lower boiling points vaporize earlier in the process, while those with higher boiling points remain in the liquid state for a longer time. This separation is achieved by utilizing a distillation apparatus, usually consisting of a heated flask or still, a condenser, and collection vessels.
The process of distillation allows for the removal of impurities, such as salts, heavy metals, or other contaminants, from the original liquid, resulting in a purer and more concentrated end product. It is widely used in the production of distilled water, alcohol, spirits, perfumes, essential oils, fuels, and many other industrial and chemical processes.
Overall, distillation is a fundamental technique for separating and purifying liquid mixtures based on their different boiling points, making it an essential process in numerous industries and scientific disciplines.

Etymology of DISTILLATION
The word "distillation" derives from the Latin word "distillare", which means "to drop or trickle down". This Latin term comes from the combination of the prefix "dis-", which signifies separation or removal, and the verb "stillare", meaning "to drip or drop". The term was adopted into Middle English as "distillen" and eventually evolved into the modern English "distillation" to refer to the process of separating and purifying liquids through the vaporization and condensation of their components.
