The explosive coke is a brown intractable powder, apparently polymeric, melting about 360° and containing nitro groups as indicated by its infrared spectrum. Since similar results were obtained from heating TNT in an inert atm and with exposure to air, oxidation must have occurred at the expense of nitro groups, which would correspondingly be converted to azo or azoxy compds or to an anthranil, by inter- and intramolecular reaction, respectively, with the... [Pg.748]

These compds can be oxidized by peracetic acid to azoxy compds. They are easily reduced, first to hydrazo compds and then to two primary amines. Azocompds are unaffected by aqueous acids and alkalies. They are sol in coned HC1 or HF acids and compds can be obtd from these solns which contain the acid... [Pg.645]

A variety of reducing agents have been used hut the usual ones are -sodium methoxide in MeOH or sodium arsenite. The azoxy compd results from the condensation of the nitroso and the hydroxylamine compds produced during the reduction. The nitroso and hy-droxyi amine compds can be prepd separately and condensed together to give the azoxy compd. Even when the nitroso and the hydroxylamine compds contain different substituted groups, with only one or two exceptions sym azoxy compds (R = R ) are formed, and not the unsym azoxy compd, as expected. Another method for prepg azoxy compds is by the oxidn of azo compds ... [Pg.664]
