Introduction: Xinyi-1B low-temperature ultrasonic extractor is a new type of chemical reaction device that uses modern ultrasonic technology combined with a low-temperature and constant-temperature system as a physical means. It is mainly composed of high-power ultrasonic generation system, heating system, compressor refrigeration system, temperature measurement and control system, and stirring system And other composition. Ultrasound refers to sound waves with a frequency higher than 20KHz. Its propagation in the medium can cause violent friction and heat dissipation between the 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 ultrasound, 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. Features: 1. The product is composed of ultrasonic generation system, heating system, refrigeration system, temperature control system and mixing system. 2. The built-in magnetic stirring system can make the reaction more complete and the temperature more uniform. 3. The special multi-necked reaction flask can meet a variety of experimental requirements (both can be flushed into various gases to participate in the reaction, but also can be continuously fed). 4. The original French Taikang refrigeration compressor has large refrigeration capacity and uniform temperature. 5. The reaction system can be completely sealed (domestic first). 6. The ultrasonic horn is immersed, and the treatment effect is good. 7. Working time and ultrasonic gap can be set. 8. Microcomputer control, the ultrasonic power is continuously adjustable. 9. The amplitude is automatically adjusted, and the amplitude remains the same under different load conditions. 10. The host controller is LCD display. Technical parameter: Ultrasonic power: 100～1500W continuously adjustable Ultrasonic frequency: 20-25KHz Cold well volume: 6L Temperature control range: -20～100℃ Temperature control accuracy: ±0.05 Compressor power: 650W Reaction volume: 10～500ml Ultrasonic probe diameter: Ф20 Optional ultrasonic probe: Ф6, Ф10, Ф15, Ф25 Stirring rate: 0~1200 rpm
