[0002] Extraction in chemical engineering is an important unit operation, mainly used to separate and extract target compounds from mixtures; extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that uses the different solubilities of components in the system in solvents to separate mixtures. Specifically, it is based on the difference in solubility or distribution coefficient of substances in two immiscible (or slightly soluble) solvents, and is a method of transferring solute substances from one solvent to another; extraction in chemical engineering is a technology that extracts substances from a mixture based on the distribution behavior of substances in two immiscible liquids. By selecting a suitable liquid phase, extractant and appropriate conditions, efficient extraction and separation of target substances can be achieved. In practical applications, extraction plays an important role in pharmaceuticals, environmental science, food analysis and other fields.
