Abstract

The reduction of aromatic nitro, nitroso, or azo compounds is effected by means of cast iron borings or turnings and an aqueous solution of a metal chloride, such as sodium, calcium, or ferrous chloride; the treatment of nitrobenzene, and of nitrophenol benzyl ethers or their homologues or halogen derivatives, is excluded. Examples are given of the reduction of p-nitrosophenol to p-aminophenol, o-nitraniline to o-phenylenediamine, p-nitroacetanilide to p-aminoacetanilide, and sodium p-hydroxyazobenbene-p1-sulphonate to p-aminophenol and sodium sulphanilate; o-nitrosophenol, o- and p-nitrophenol, p-nitraniline, o-nitroacetanilide, and sodium 2-nitro-4-aminobenzene sulphonate are also specified as parent materials.
