The separation of the volatile parts of a substance from the more fixed; specifically, the operation of driving off gas or vapor from volatile liquids or solids, by heat in a retort or still, and the condensation of the products as far as possible by a cool receiver, alembic, or condenser; rectification; vaporization; condensation; as, the distillation of illuminating gas and coal, of alcohol from sour mash, or of boric acid in steam.
The substance extracted by distilling.
The process of separating the components of a mixture by differences in boiling point; a vapor is formed from the liquid by heating the liquid in a vessel and successively collecting and condensing the vapors into liquids.
takes place in pear-shaped copper vessels called 'pot stills' and at least two, sometimes three, are required of different types for malt whisky. First the wash is distilled to produce an intermediate product called the low wines. These then go into a second still for further distillation. The whisky then passes into a spirit store, ready to fill into barrels. Distillation is the separation of a mixture of chemical compounds through their different boiling points. Heating a weak alcoholic liquid causes the alcohol to evaporate before the water. When the alcohol is condensed back into liquid it has increased in strength.
operation done either in stills or in distillation columns, whose aim is the separation and concentration of alcohol and the most volatile and aromatic compounds of fermented wort.
Vaporization of a substance with subsequent recovery of the vapor by condensation. Often used in less precise sense to refer to vaporization of volatile constituents of a fuel without subsequent condensation.
Distillation refers to the boiling of water to make steam, which is then collected and condensed for drinking. It's expensive because of the amount of energy it uses. Distillation is available as point-of-use or -entry system. Some pollutants are concentrated by distillation.
The process used to separate two or more liquids that have different boiling points.
Distillation is a technique for separating components of a mixture on the basis of differing boiling points. The mixture is heated, vaporizing some of the components. The vapor is collected and condensed to isolate the components with the lowest boiling points.
The process of seperating the components in a liquid by heating it to the point of vaporization, then cooling so it condenses into a purified form.

A process in which essential oils are extracted from plant materials using steam and pressure. Steam passes through fresh plant material, causing the cell walls of the plant to break down and release the essential oil. The water and essential oil vapor then pass through a cooler that condenses the steam and the oil into a liquid. When the liquid is collected, the oil is separated from the water.
A process by which fermented liquid is boiled then cooled, so that the condensed product contains a higher alcoholic concentration than before” ( Levinthal, 176).
The process involving the conversion of a liquid into vapor that is subsequently condensed back to liquid form. When beverages containing alcohol are heated, the alcohol evaporates more quickly than the water. The alcohol can then be condensed and collected, yielding a beverage with a much higher alcohol concentration than the original. This is the basis for making “distilled spirits,” also known as “hard liquors”.
A technique used to purify water by removal of inorganic contaminants such as salts through heating the solution and condensing the steam. The resultant distilled water has a reduced salt concentration. Distillation is not effective in removing pesticides and volatile organic contaminants (VOCS) such as chloroform and benzene.

The separation and purification of a mixture of components by vapourisation followed by condensation, based on the different volatilities of each component. A typical experimental set up for distillation is shown below
the first step in the refining process. During distillation, crude oil is heated in the base of a distillation tower. As the temperature increases, the crude's various compounds vaporize in succession at their various boiling points, then rise to prescribed levels within the tower (according to their densities), condense in distillation trays and are drawn off individually for further refining. Distillation is also used at other points in the refining process to remove impurities.
a method for separating the components of a liquid mixture that depends on differences in the ease of vaporization of the components.
The process whereby alcohol is extracted from a liquid by the use of heat. Since alcohol vapourizes at a lower temperature than water, it can be collected and condensed back to liquid form.
The primary method of producing essential oils is through steam distillation. Distillation is an age-old process. While the crude still of the past (almost identical to the simple country "moonshine" still) is now often replaced with modern, stainless steel versions, the process is still basically unchanged. Water is heated to boiling and steam passes through fresh plant material stacked on a rack above the boiling water, causing the cell walls of the plant to break down and release the essential oil. The water and essential oil vapor then pass through a cooler that condenses the steam and the oil into a liquid. The liquid is collected and the oil separates from the water. Most oils are lighter than water and thus collect on the surface of the water where they are siphoned off. Oils heavier than water sink to the bottom of the collector where they are removed. Some stills use "direct," or "water" distillation where the plant material is mixed with the boiling water with the same effect.

Turning liquid into vapour â€“ usually done by heating.
Process of vaporising a liquid and collecting the vapour, which is then usually condensed to a liquid. In industry, this process is widely used to separate the components in a liquid solution. Since every pure compound boils at a specific temperature, it is often possible to boil off one liquid while most of the higher boiling point material remains in its liquid state. It is extremely difficult and sometimes impossible to separate materials in this way when they boil at the same, or near the same temperature.

is the main method of obtaining essential oils from plants, other methods being enfleurage, maceration, expression and extraction. Distillation is based on the principal that when plant material is placed in boiling water, the essential oil in it will evaporate with the steam; once the steam and oil have then condensed back, the oil will separate from the water, floating on the water's surface, from which it can be collected. Sometimes this process is repeated to obtain a purer essence.
The process of driving off gas or vapor from liquids or solids by heating and condensing to liquid products. The three main types of distillation are evaporation*, descension*, and filtration.
Plant material such as leaves, flowers, wood etc. are arranged in a receptacle ('Still') Steam is passed through the plant material. Volatile chemicals that make up the "essential oil" held in the cells of the plant material are vaporized and thus released into the path of the steam. The Steam carries the oil out of the still to a condenser which cools the Steam & Oil mixture. The mixture drips into a separating container (Florentine flask) The old adage "oil and water do not mix" is ever true in this case and the oil (usually) floats to the top. This oil known as an 'Essential Oil' is usually of a light colour as the colour molecules in the plant material, such as chlorophyll are large and non-volatile. The techniques used for each specific plant material are slightly different. See Steam Distillation, Water Distillation and Destructive Distillation.
