What does extraction technology mean?

Extraction is one of the methods used to purify and purify compounds in organic chemistry laboratory. By extraction, the desired compound can be extracted from a solid or liquid mixture. Extraction is a unit operation, which separates the mixture by using the solubility difference of each component in the solvent [3]. In recent years, it has been widely used in the industrial field. This paper briefly introduces the related technologies of extraction.

Using the difference of solubility or partition coefficient of the compound in two immiscible solvents, the compound is transferred from one solvent to another. After repeated extraction, most of the compounds were extracted.
