Chemiluminescence in the course of methyl ethyl ketone oxidation by ozone in acidic aqueous solutions

Chemiluminescence in the visible spectral region is observed in the course methyl ethyl ketone oxidation by ozone in neutral and acidic aqueous solutions. The spectral composition of the chemiluminescence is studied. On going from neutral to acidic aqueous solutions of methyl ethyl ketone, the initial intensity of the signal increases and the kinetics of a decrease in the chemiluminescence intensity changes. A radical scheme of the process is proposed to explain the results obtained.Translated from Kinetika i Kataliz, Vol. 45, No. 6, 2004, pp. 829–835.Original Russian Text Copyright © 2004 by Zimin, Gusmanov, Khursan.
