Glyoxal could also be derived by this pathway by an oxidation/reduction process. Both of these
compounds would be precursors to oxalic and formic acids.
Differences in carboxylic acid content observed by the UV method and the conductivity method
(for example, formic acid and glyoxylic acid) suggest that positive identifications must be ad-
dressed by additional techniques.
CONCLUSIONS
In conclusion, the laboratory oxidation of ADNTs by peroxone AOT proceeds rapidly to prima-
rily innocuous products. Ozone in the peroxone system appears to dominate the ADNT loss pro-
cess. Product studies indicate that the ring is ruptured readily with the release of nitrite and nitrate
ions.
