Abstract

[0002] Distillation is a commonly used purification method in organic chemistry. It is suitable for liquid organic substances with large differences in boiling points. Distillation uses the difference in vapor pressure of different substances at different temperatures to achieve separation. When a mixture is heated to the boiling point of a component, the component will evaporate first, and then a relatively pure substance can be obtained through condensation. Distillation is an operation process with high technical requirements and needs to be carried out strictly in accordance with experimental procedures and safety specifications. In actual operation, other factors may need to be considered, such as changes in pressure, complexity of the mixture, etc., to ensure the purification effect. For more complex mixtures, fractional distillation, vacuum distillation or other advanced technologies may be required to achieve more effective separation.
[0003] During the distillation and purification process of chemical organic raw materials, people need to clean up the residue in the distillation tank before they can proceed to the next work. Most of these residues will be deposited at the bottom of the tank, which takes a lot of time to clean. In addition, the internal space of the tank is small, which is not convenient for people to clean, thereby reducing the cleaning efficiency. Utility Model Content
