extraction column

The transfer of a compound from one solvent to another by the use of a different solubility or partition coefficient of the compound in two mutually insoluble (or slightly soluble) solvents. Most of the compounds were extracted after repeated extraction and transfer. The law of distribution is the main basis of the extraction method, and the material has different solubility to different solvents. In two immiscible solvent, adding a soluble substance, it was dissolved in two solvents, experiments show that under certain temperature, the compound and the two kinds of solvent does not decompose, electrolysis, association and solvation effect, this compound is a fixed value. In the two layer of fluid ratio
