Sonochemistry: innovations and challenges

Sonochemistry, based on the use of ultrasonic waves in the power range from 20 to 2,000 kHz, has great potential as a breakthrough technology for a variety of chemical applications. This field, still under-exploited and sometimes considered only as a method of agitation, can lead to new reactivities and improvements in process efficiencies. . The many examples reported at laboratory scale in organic chemistry, catalysis, materials preparation, polymer synthesis or degradation, extraction, effluent treatment and many others confirm the importance of overcoming the technical...
