Application of Sonochemical Activation in Green Synthesis

The application of ultrasonic irradiation for the activation of chemical reactions, commonly known as sonochemistry, has contributed to the development of a number of processes that are considered to be environmentally benign. The use of ultrasonic waves to activate synthetic processes usually results in shorter reaction times and higher yields and selectivities, namely, cleaner products. This work aims to provide an overview of recent applications that illustrate the use of sonochemistry in the field of green or sustainable synthesis. In the first part of the chapter, organic synthetic processes are surveyed, including applications in aqueous, nonaqueous, or biphasic systems as well as homogeneous and heterogeneous catalytic reactions. In the second part of the work, the focus will be on an emerging field, the preparation of nanoparticles.
