Dinitro compds

By addition of nitrogen dioxide, nitrosates (II) (nitroso-nitrates) or dinitro compds (III) or dinitrites (IV) are obtained. Nitrosates (II) can be oxidized to nitro-nitrates (Ila), viz ... [Pg.422]

The product was a mixt of the dinitro compd, the di-NH4 salt of 2,4-C10H6(NO2)2, m-nitro-naphthylazimidole and some 2,4-dimtro naphthalene. The reaction of anhyd hydrazine with l-chIoro-2.4-dinitronaphthalene gave only the 4,4 -dinitro-2,2 -azonaphthaiene and 2,4-dinitronaphthalene (Refs 1 2)... [Pg.656]
