[0002] Hydroxyacetic acid, also known as glycolic acid or glycolic acid, is a chemical substance with the dual properties of alcohol and acid. It is soluble in water, methanol, ethanol, acetone, acetic acid and ether, but almost insoluble in hydrocarbon solvents. Hydroxyacetic acid is widely present in nature and is usually produced by synthesis in industry. The main uses of glycolic acid include cosmetics, chemical synthesis, medicine, textile and mechanical industries, etc.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing hydroxyacetic acid production and purification device purifies the reactants, it is necessary to go through the steps of separation, extraction, distillation, crystallization, etc. When separating, the reactants need to be separated by filtering or centrifugation to remove the catalyst and unreacted raw materials. However, the separation effect is easily affected by problems such as clogging during separation. It is necessary to manually stop the separation work and open the tank to clean the filter cartridge, which is time-consuming and labor-intensive. Utility Model Content
