The growth and collapse processes of cavitation bubbles under ultrasonication lead to generation of enormous pressures and temperatures, so that physical and chemical effects emerge at the local locations in the liquid in a reactor. The chemical reaction processes utilizing these effects are called sonochemical processes. On designing the sonochemical reactor, it is important to know how a variety of physical or chemical parameters influence acoustic power or cavitation intensity. The purpose of this study is to investigate the relation between the pressure or temperature and the efficiency of the chemical reaction induced by ultrasonication in a flow-type sonochemical reactor. The frequency-dependence of the transducer impedance was investigated under the different pressure and temperature conditions. The effects of the pressure and temperature on the sonochemical effect were evaluated by KI dosimetry.
