    摘要: MONOAZO DYESTUFFS ARE PREPARED BY COUPLING A 3-DIAZO6-ALKOXYBENZENE SULFONIC ACID AND AN A-NAPHTHOL DISULFONIC ACID AND PRECIPITATING THE DYE, EITHER AS THE FREE ACID OR AS AN AMMONIUM OR METAL SALT. THE TRISODIUM SALTS ARE PREFERRED BECAUSE OF THEIR LOW TOXICITY TO WARM-BLOODED ANIMALS. THE DYESTUFFS ARE USEFUL AS COLORANTS FOR FOODS, PHARMACEUTICALS, COSMETICS, AND THE LIKE, AND FORM ALUMINUM LAKES USEFUL AS PIGMENTS FOR PLASTICS.
