The effect of CCl2F2 on ozone generation from oxygen

The production of ozone by negative corona discharge from O-2 + CCl2F2 (CFC 12) mixtures is experimentally investigated at two pressures of gaseous mix ture of 800 and 900 mbar in the CCl2F2 concentration range of (0-7)%. The e fficiency of ozone generation is remarkably reduced with increasing content of CCl2F2 in the mixture with oxygen. The effect is more apparent at lower pressure of gaseous mixture. In order to identify the most likely process responsible for the inhibition of ozone production a discussion of the chem ical kinetics of various processes is presented.
