- Benefits of Ultrasounds -
The origin of sonochemical effects in liquids is the phenomenon of acoustic cavitation, which is "the formation, growth, and implosive collapse of bubbles in a liquid".
Cavitational collapse produces intense local heating (~5000 K), high pressures (~1000 atm), and enormous heating and cooling rates (>109 K/sec) and liquid jet streams (~400 km/h). The use of ultrasounds (sonochemistry) can result in several (beneficial) effect in chemical reactions and processes:
- increase in reaction speed
- increase in reaction output
- more efficient energy usage
- switching of reaction pathway
- performance improvement of phase transfer catalysts
- avoidance of phase transfer catalysts
- use of crude or technical reagents
- activation of metals and solids
- increase in the reactivity of reagents or catalysts
