在水/氯仿两相体系中，钼酸根催化的芳香族化合物溴化反应是在超声波辐射下进行的，而在常规机械搅拌下(1400rpm)没有发生。声化学活化是次要作用，归因于CHCl3-H2O混合溶剂的超声分解降低了pH。
The Molybdate-catalyzed bromination of various aromatic compounds in the presence of KBr/H2O2in an aqueous/chloroform biphasic system occurred under ultrasonic irradiation, whereas the reaction did not take place under conventional mechanical stirring (1400rpm). The sonochemical activation was found to be of secondary effect, attributed to lowering pH by sonolysis of CHCl3–H2O solvents mixture.
