Decomposition of an aqueous solution of acetic acid under the action of an atmospheric-pressure dielectric barrier discharge in oxygen in a fl ow-through reactor was studied. A mechanism of chemical reactions is suggested, which describes the decomposition of the acid and formation of the reaction products observed.

The kinetics of phenol degradation in aqueous solution in an atmospheric pressure dielectric barrier discharge in oxygen at different power inputs to the discharge has been investigated. On the basis of these data, the energy yields of degradation and their dependence on the discharge parameters and initial concentration have been determined. The problem of comparing the energy efficiencies of different types of discharges has been discussed. The decomposition of phenol has been shown to result in the formation of car boxylic acids and aldehydes in the solution and carbon dioxide in the gas phase.
