What is Short Path Distillation
As a type of thermodynamic separation technology, the equipment can evaporate components with low boiling points by utilizing that the boiling point of each component in the mixed liquid or liquid-solid mixture is different, and then condense the material to separate the whole components. It is the combination of evaporation and condensation unit operations as well as a kind of liquid-liquid separation technology.
Why Use Short Path Distillation
The short path distillation is a technique that removes solvents from mixtures through evaporation, which is mainly used for liquid-liquid separation. As one of the most high-efficiency distillation techniques in people’s using, it can solve the problems that conventional distillation technology can’t.
As well, there are other possible reasons why the short path distillation is so widely used. Firstly, it requires a smaller working space compared to most conventional distillation techniques, which is much easier to use. And the desired purity level can also be reached. Secondly, it has a relatively low distillation temperature. Compared to the simple distillation, the materials can be separated even though there is a small temperature difference. Thirdly, the short path distillation is a physical process, which can well protect separated substances from being polluted and damaged. Furthermore, the less material will be lost because the liquid only need travel a short distance in the short path distillation. It efficiently reduces material waste. Therefore, the short path distillation has become more and more well-received.
how does short path distillation work
1. Molecules diffuse from the liquid phase to the evaporation surface:
The beginning of the short path distillation’s working is from evaporation flask. Sample will be placed in the evaporation flask and be heated by the heating mantle. The temperature that heating mantle provides can be adjusted according to the boiling points of different solvents.
2. Free evaporation of molecules on the liquid surface:
The evaporation speed of solvents can be changed by the heating temperature. Besides, the stability of sample solvents is also an important factor influencing the evaporation speed.
3. Molecules fly from the evaporation to the condensation surface:
The extracted gas-phase solvents will be transferred along a short distance, and be condensed along this distance. During this process, gas-phase solvents will be cooled down by the condensing part and turned into liquid-phase solvents.
4. Solvents will be collected in the receiving flask:
After gas-phase solvents being turned into liquid-phase solvents, it will be transferred into receiving flask and be collected efficiently. Collecting extracted solvents in the receiving flask is very convenient for users to get.
In the whole working process of short path distillation, there are always vacuum pump providing vacuum and condensing part turning gas-phase solvents into liquid-phase solvents.
