High intensity ultrasound induces, micro bubbles which are called cavitation bubbles with high temperature and high pressure. It is reported that the sonochemical reaction occurs at the inside of cavitation bubbles and their interface. In this work, it is defined that the sonochemical reaction occurs at three regions "Inside of bubble", "Gas-liquid interface" and "Interfacial region". "Interfacial region" is defined as the surrounding zone of the Gas-liquid interface, and the solute in this region is decomposed by heat and OH radicals. Surface activity of octyl benzene sulphonate (OBS) is much larger than aniline and phenol. When aqueous OBS-Phenol mixed solution and aqueous Aniline-Phenol mixed solution were sonicated, the restrain of degradation of Aniline was larger than that of OBS. It was suggested that degradation region of OBS was mainly "Gas-liquid interface" and that of Aniline and Phenol was mainly "Interfacial region".
