[Chemical Knowledge]：The principle of distillation columns: the mystery of separating high-purity substances from mixtures

The rectification column principle is a separation method based on differences in boiling points, which usually includes two steps: heating the mixture to boiling point and separating the different components. Due to the different boiling points of different components, after heating the mixture, the components with lower boiling points will boil first, and as the temperature increases, the components with higher boiling points will also begin to boil. At this time, by controlling the temperature of the different layers, the different components can be separated.

distillation column is an efficient device to achieve this principle, usually by the tower, packing, boiling point meter, condenser and a series of components. In the process of distillation, the mixture will enter the tower body from the top or bottom of the tower, then descend along the tower wall, and be separated into different components with the help of packing. These components can be separated through the column layers and cooled and condensed in the condenser.

distillation column is widely used in many fields, such as chemical industry, food, medicine and so on. In the field of chemical industry, it is used to separate the mixture of chemical reactions; in the food industry, the principle of distillation tower can be used to separate high purity citric acid from the aqueous solution of citric acid; in pharmaceutical manufacturing, the distillation tower is also used to separate and synthesize high purity active ingredients. The principle of

distillation column is an efficient method for separating different components in a mixture, which is widely used in many fields. With the continuous progress of technology, the application range of distillation column will continue to expand, bringing more benefits to human production and life.
