Reaction CXXI.—Action of Tetranitromethane on Bases

Reaction CXXI. Action of Tetranitromethane on Bases. (B., 1920, 53, 1529.)—The tetranitromethane is decomposed by weak bases in alcohol or acetone solution into nitroform and nitric acid. [Pg.281]

C(N03)4 + H20 — HC(N02)3 + hno3, the base becoming nitrated during the process. [Pg.281]

Reaction CXXII. Action of Phenols and Aromatic Amines on Diazonium Compounds.—Diazonium compounds combine with phenols and aromatic bases to form azo dyestuffs. [Pg.282]

The process is known as coupling. R is seldom aliphatic. In the azo compound N is trivalent, while in the diazonium compound N is pentavalent. The diagram shows the name given to the different groups in the azo compound. [Pg.282]

Laws op Formation op Azo Colours Bases are coupled in slightly acid solution, while phenols are coupled in slightly alkaline solution. [Pg.282]
