The Mechanism of Nitrogen Fixation under Ultrasonic Radiation in Water

摘要

Research covering a two year period is briefly discussed. Basically it delt with the sonolysis. Molecular fragmentation of organic liquids was produced by cavitation due to ultrasound waves, even in the absence of water. The sonolysis of acetonitrile under argon yielded N2, CH3, and H2. Excited singlet oxygen molecules in solution were shown to be formed in the reaction of H2O2 with HOCl (or Cl2) or with alkaline pyrogallol. The formation of OH radicals under sonolysis has been investigated by following the oxidative deamination of ethylenediamine.
