Why is there better separation of two liquids achieved by slow rather than fast distillation? By getting rid of the bad stuff and purifying your drinking water, you can ensure that your organs are functioning properly and absorbing the minerals and vitamins you need most.

The principle of fractional distillation is that different liquids boil at different temperature. The miscible liquids boil at different temperature and evaporate at different temperature. When the mixture is heated, the liquid with lower boiling point boils and turns into vapours. Fractional crystallization is a cascade process as it involves the purification of the substance to the highest degree of purity.

Also fractional crystallization is ineffective in separating enantiomorphs which have identical physical property. Fractional distillation is used for the purification of water as well as separating acetone and water. Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.

Distillation is a method of separating mixtures based on differences in their volatiles in a boiling liquid mixture.

Distillation is a unit operation, or a physical separation process, and not a chemical reaction. Water is distilled to remove impurities, such as salt from seawater.

Water Distillation. Cost is one of the main reasons why few bottlers use distillation. The major cost factor is equipment. The cost of energy required to heat the water to boiling in the distillation process has made even the cost of producing a gallon of distilled water a lot more expensive than RO.

The process of distillation begins with heating a liquid to boiling point. The liquid evaporates, forming a vapor. The vapor is then cooled, usually by passing it through pipes or tubes at a lower temperature. If these compounds have different boiling points, you can separate them using distillation. The ability to produce high product purity. Many of the alternatives to distillation only carry out a partial separation and cannot produce pure products. It is no accident that distillation is the most common method for the separation of homogeneous mixtures.

It is a versatile, robust and well-understood technique. For example, fractional distillation is used in oil refineries to separate crude oil into useful substances or fractions having different hydrocarbons of different boiling points.

This process gradually enriches the vapor phase in favor of the most volatile component. After a sufficient number of evaporation and condensation cycles have taken place, the final condensate contains a liquid that is en- riched in the more volatile component. Distillation is easier to understand if we envision a spesific mixture of two liquids, say diethyl ether and ethanol. When we boil this mixture, we observe the following: the entire mixture both compounds boils, but the vapor phase is enriched in the more volatile component diethyl ether.

As this vapor mixture rises, cools, and condenses, the resulting liquid is enriched in diethyl ether too. If we attach a column to the flask so that the vapor enters this column, the condensing liquid will be heated by rising vapors, and it will boil again producing a vapor that is even more enriched in diethyl ether. The higher the column, the more times this cycle of evaporation-condensation can be repeated, and the higher up we sample the vapor, the more enriched the vapor phase will be in the more volatile component diethyl ether.

Ideally, with a long enough column, one could obtain a vapor that is nearly pure diethyl ether, and leave behind a liquid that is nearly pure ethanol, the less volatile component. Let us discuss a typical distillation apparatus shown above We start with a flask containing the solution often called a still pot , which is heated.

You can see from our discussion above, that a key feature of a distillation apparatus must be a column, where many cycles of condensation and evaporation can take place.

This is typically less efficient. The column can be packed with an inert material, which is the basis of a fractional distillation, and typically constitutes a more efficient distillation.

The inert material, such as copper sponge or glass beads, provides a large surface area, thus allowing many more evaporation-condensation cycles. The column is attached to an adapter. In the top of this connector is the thermometer, which is used to read the temperature of the vapor, just as it condenses.

The temperature reading is important, because, at normal conditions, the temperature of the vapor passing through is the same as the boiling point of the substance being collected. Vapor that passes the thermometer condenses in the condenser, a double-walled tube that is cooled by water flowing through the outer layer, and drips into the receiver.

Before moving on, let us look at benefits and drawbacks to a simple distillation versus a fractional distil- lation. We have already said that the simple distillation is less efficient at separating liquids, because there is a smaller surface area inside the column, but it is usually much faster.
