Das o-Nitro-o-amido-p-acetamidophenol, welches durch Dinitrierung von ρ - Acetamidophenol und partielle Reduktion des Dinitroderivats erhalten wird, läßt sich durch salpetrige Säure in eine orangegelb gefärbte Diazoverbindung überführen, die sich mit Amidonaphtol- und Dioxynaphtalinsulfosäuren zu sehr wertvollen Farbstoffen vereinigt. Diese besitzen die Eigenschaft, Wolle inThe o-nitro-o-amido-p-acetamidophenol, which by dinitration of ρ - acetamidophenol and partial reduction of the Dinitro derivative is obtained can be converted into an orange-yellow colored by nitrous acid Diazo compound convert, which deals with amidonaphthol and dioxynaphthalene sulfonic acids combined to form very valuable dyes. These have the property of being wool in
ίο blauen Tönen zu färben, die durch Nachbehandlung grünstichiger und hervorragend wasch-, walk- und lichtecht werden. Die Farbstoffe egalisieren vorzüglich.ίο blue tones to color by post treatment become more greenish and excellent wash, squeeze and lightfast. The dyes level out excellently.
Von den analogen Derivaten des o-Nitroo-amido-p-kresols und des o-Nitro-o-amidop-chlorphenols, welche in den französischen Patentschriften 300275 und 312792 bezw. der Patentschrift 139213 erwähnt sind, unter-Of the analogous derivatives of o-nitroo-amido-p-cresol and o-nitro-o-amidop-chlorophenol, which respectively in French patents 300275 and 312792. the patent 139213 are mentioned, under-

scheiden sich die neuen Kombinationen namentlich durch ihre lebhafteren Töne und ihre hervorragende Egalisierungsfähigkeit.The new combinations are distinguished by their livelier tones and their excellent leveling ability.
21,1 kg Nit-roamidoacetamidophenol werden in 100 1 Wasser und 35 kg Salzsäure von 2O° Be. gelöst und die Lösung bei O° mit 7,3 kg Nitrit versetzt. Die so erhaltene Diazoverbindung wird in eine Lösung von 36 kg ι · 8 -Amidonaphtol-3 · 6 -disulfosäure und 35 kg Soda eingetragen. Nach etwa 12 Stunden ist die Farbstoffbildung beendet. Der Farbstoff wird dann ausgesalzen und abfiltriert. Er färbt Wolle in saurem Bade blau, durch Nachchromierung geht die Farbe in Blaugrün über.21.1 kg of nitroamidoacetamidophenol will be in 100 l of water and 35 kg of hydrochloric acid at 20 ° Be. dissolved and the solution at 0 ° with 7.3 kg of nitrite added. The diazo compound thus obtained is dissolved in a solution of 36 kg ι · 8-amidonaphtol-3 · 6 -disulfonic acid and 35 kg of soda entered. The formation of the dye has ended after about 12 hours. The dye is then salted out and filtered off. He dyes wool blue through in an acid bath After chrome plating, the color changes to blue-green.
