Man mischt 22,7 Teile 4.4'-Diaminobenzanilid mit 50 Vol. Teilen Salzsäure mit 20°Be und 300 Teilen eines Eis-Wassergemischs und tetrazotiert mit 28 Vol.Teilen einer 5Q#igen Natriumnitritlösung. In die Lösung des Tetraazoderivats führt man danach eine Lösung aus 14,2 Teilen Salicylsäure, 10 Vol.Teilen Natriumhydroxidlösung mit 36°Be, 32 Teilen Natriumcarbonat und 300 Teilen Wasser ein. Nach 15 Minuten Rühren gießt man in dieses Gemisch eine 100C warme Lösung von 11 Teilen 1.3-Dihydroxybenzol in 300 Teilen Wasser. Man bringt dann die Temperatur auf 500C und gibt 8o Teile Natriumchlorid zu. Den so erhaltenen Farbstoff filtriert und trocknet man. Er färbt Baumwolle in oranger, lichtechter Farbtönung.22.7 parts of 4,4'-diaminobenzanilide are mixed with 50 parts by volume of hydrochloric acid with 20 ° Be and 300 parts of an ice-water mixture and tetrazotized with 28 parts by volume of a 5Q strength sodium nitrite solution. A solution of 14.2 parts of salicylic acid, 10 parts by volume of sodium hydroxide solution containing 36 ° Be, 32 parts of sodium carbonate and 300 parts of water is then introduced into the solution of the tetraazo derivative. After stirring for 15 minutes, a 10 ° C. solution of 11 parts of 1,3-dihydroxybenzene in 300 parts of water is poured into this mixture. Then bringing the temperature to 50 0 C. and 8o parts of sodium chloride. The dye thus obtained is filtered and dried. It dyes cotton in an orange, lightfast shade.
