CHAPTER 7. Green Synthetic Procedures under Hydrodynamic and Acoustic Cavitation

Abstract

This chapter aims to stimulate further progress in organic synthesis by describing harmless and green cavitational technologies that are well suited to heterogeneous-phase and catalysed reactions. Hydrodynamic cavitation and ultrasound create unique high-energy microenvironments and their accompanying hot-spots, shock-waves, micro-jets and shear forces. In addition to outstanding mass transfer and mechanochemical effects, the formation of highly reactive, intermediate radical species can initiate mechanistic paths that do not occur under classical conditions.
