Description
Technical Field
The invention relates to the field of education, in particular to an extraction detection device for a chemical experiment.
Background
Extraction, also known as solvent extraction or liquid-liquid extraction, also known as extraction, is a unit operation that separates mixtures by utilizing the different solubilities of components in the system in a solvent. That is, the method is a method of transferring a solute substance from one solvent to another solvent by utilizing the difference in solubility or partition coefficient of the substance in two solvents which are not soluble (or slightly soluble) with each other. The method is widely applied to chemical, metallurgical, food and other industries and is generally applied to petroleum refining industry. The operation of separating the two immiscible liquids after extraction is called liquid separation.
Solid-liquid extraction, also known as leaching, uses a solvent to separate the components of a solid mixture, such as water to extract sugars from sugar beets; extracting soybean oil from soybeans with alcohol to increase oil yield; the leaching of effective components from Chinese medicinal materials with water to obtain fluid extract is called "percolation" or "leaching".
Although extraction is often used in chemical experiments, its operation does not cause a change (or chemical reaction) in the chemical composition of the extracted substance, so the extraction operation is a physical process.
Extraction is one of the means used in organic chemistry laboratories to purify and purify compounds. The desired substance can be extracted from the solid or liquid mixture by extraction.
