A cannabis product produced by removing everything except for a specific cannabinoid, generally THC or CBD.
Summary from Wikipedia:
Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.
Distillation has many applications. For example:
- Distillation of fermented products produces distilled beverages with a high alcohol content or separates out other fermentation products of commercial value.
- Distillation is an effective and traditional method of desalination.
- In the fossil fuel industry, oil stabilization is a form of partial distillation that reduces vapor pressure of crude oil, thereby making it safe for storage and transport as well as reducing the atmospheric emissions of volatile hydrocarbons. In midstream operations at oil refineries, distillation is a major class of operation for transforming crude oil into fuels and chemical feed stocks. Refining oil involves taking a raw material like crude oil and distilling or purifying it into usable fractions and products like gasoline, kerosene, and even plastics. This is done by heating the crude oil and discharging the resulting liquids and vapors into towers. Inside the towers, the liquids separate according to their weight and boiling point. When crude oil is fractionally distilled you can observe the different fuels and raw materials produced at different heights in the distillation tower. Small molecules that have low boiling points, are very volatile, flow easily, and ignite easily rise to the top of the tower like gases and gasoline. Larger molecules with high boiling points that are not very volatile and do not flow or ignite very easily fall to the bottom of the tower including fuel and diesel oils as well as petroleum. Products like kerosene and naphtha stay around the middle.
- Cryogenic distillation leads to the separation of air into its components – notably oxygen, nitrogen, and argon – for industrial use.
- In the field of industrial chemistry, large amounts of crude liquid products of chemical synthesis are distilled to separate them, either from other products, from impurities, or from unreacted starting materials.
An installation used for distillation, especially of distilled beverages, is known as distillery. The distillation equipment at a distillery is a still.Read more
