Abstract
Bz-21-Oxybenzanthrone is prepared from 11-diazo-21-oxybenzanthrone anhydride by replacing the diazo group by hydrogen. The diazo-oxy-anhydride may be obtained by nitrating 11-acetaminobenzanthrone, saponifying, and diazotizing; the benzanthrone-21-nitro-11-diazonium salt is then converted into the diazonium hydrate (either by hydrolysis or by removing the acid radicle by means of alkali sulphate, alkali acetate, bicarbonate &c.), whereupon the diazo-oxy-benzanthrone anhydride is formed, nitrous acid being eliminated. In an example 11-diazo-21-oxybenzanthrone anhydride is treated with stannous chloride and caustic potash solution; the 21-oxybenzanthrone obtained is purified by dissolving in alkali and reprecipitating; it yields with dimethylsulphate and alkali, a methoxy compound which, upon alkali fusion, forms a dyestuff dyeing cotton from the vat in green tints. Specification 218,255 is referred to.
