Problems solved by technology

[0003] At present, many extraction equipment require manual operation, and continuous extraction is not possible, which greatly reduces the extraction efficiency. In addition, the inability to perform continuous extraction leads to a large amount of extraction agent, resulting in unnecessary losses.

Description

technical field [0001] The invention belongs to the technical field of extraction equipment, and in particular relates to a rapid extraction method for realizing organic compounds. Background technique [0002] Extraction refers to the transfer of a compound from one solvent to another by using the difference in solubility or distribution coefficient of the compound in two immiscible (or slightly soluble) solvents. After repeated extractions, most of the compounds are extracted. In chemical laboratories, the existing extraction devices are mostly very simple. The main method is to pour the two solutions into a beaker, and then use a glass rod to continuously stir, and then The mixed solution is poured into the extraction bottle, and the layered solution is released layer by layer through the control knob. [0003] At present, many extraction equipment require manual operation, and continuous extraction is not possible, which greatly reduces the extraction efficiency. In add...
