Short-Path Distillation VS. Simple Distillation
Distillation is widely used in the industrial field to extract or purify substances. There are several ways of distillation and the most essential one is simple distillation. Simple distillation is one single-stage distillation technique that directly condenses the boiled solvents into liquid-phase. Short-path distillation is one of the most classic simple distillation. In the short-path distillation, sample can get heated and evaporated in the specialized evaporation flask. Then gas-phase extracted solvents will be transferred along the short distance and be condensed into liquid-phase during this distance. Finally, the liquid-phase extracted solvents will go into receiving flask and be collected there. It is convenient for users to take the extracted solvents away from receiving flask. Short-path distillation is very convenient and high-efficiency for users to extract or purify substances.
The Uses of Short-Path Distillation
Short-path distillation has been used for a long time in the industrial field, chemical field, biochemical field, food-making field and other fields. For example:
1. In industrial field, people always use short-path distillation for the extraction and purification of substances. For example, the regeneration of waste oil, which is to regenerate waste oil by using short-path distillation. It is very environment-protecting, sustainable and economic for our society. The separation and refinement of peppermint essential oil is also made by short-path distillation through water vapor method, which is to evaporate the excess water out of peppermint essential oil. There are some other examples of the extraction or purification made by short-path distillation.
2. In chemical field, short-path distillation is widely used in chemical labs. For example, the separation and refinement of octacosanol by short-path distillation is pretty popular in chemical labs. The purification of pepper butyl ether is also made by short-path distillation. There are some more uses of short-path distillation in chemical field.
3. In food-making field, people always use short-path distillation to make juices thicker. For example, fruit juice can be purified and refined by short-path distillation through evaporating the excess water in fruit juice. What’s more, there are some other examples of refining or purifying liquid-phase substances in people’s daily life.
Besides, there are more uses of short-path distillation in other fields. And there will be more useful functions of short-path distillation for people to discover.
