Abstract

An apparatus is described in which radicals can be identified by ESR and molecular products by polarography or gas chromatography. The radicals are removed from the reaction mixture through a micro-leak and condensed in a matrix on a cold finger. From a study of the system, 1 H2 (1 D2) - 1 O2 - 4 N2 at 546°C and a pressure of 1 atm, in reactors with and without a B2O3 coating, evidence has have been produced for the presence of HO−2 and DO−2 radicals. Following the earlier suggestion that the formation of H2O2 occurs by bimolecular reaction of HO−2, a mechanism is studied and compared with the experimental results.
