Overview of Ultrasonic Extractor

It is mainly composed of high-power ultrasonic generation system, heating system, compressor refrigeration system, temperature measurement and control system, mixing system, etc. Ultrasound refers to sound waves with a frequency higher than 20000 Hz. Its propagation in the medium can cause violent friction and heat dissipation between medium molecules, thereby producing various primary and secondary ultrasonic effects, such as ultrasonic thermal effects, chemical effects, cavitation effects, and other physical effects. The "cavitation" effect of ultrasound can cause changes in the activity of the reaction system, generating instantaneous high temperature and high pressure enough to initiate chemical reactions, forming local high-energy centers, and promoting the smooth progress of chemical reactions. This is the main factor for ultrasonic catalyzed chemical reactions. The secondary effects of ultrasonic, such as mechanical shock, emulsification, diffusion, crushing, etc., are conducive to the full mixing of reactants in all directions, and are more effective than general phase transfer catalysis and mechanical stirring to promote the smooth progress of the reaction, so ultrasonic technology has gradually entered The chemical laboratory, as a means of physical catalysis, has greatly improved the appearance of organic medicinal chemistry reactions.
