Description
Verfahren zur Herstellung eines Nachchromierungsfarbstoffes. Es wurde gefunden, dass man einen neuen Nachchromierungsfarbstoff herstellen kann, wenn man diazotiertes 4-Nitro-2-aminophenol mit 1- Amino-5-oxynaphtaliri-7-sulfosäure in Gegenwart von Calciumhydroxyd kuppelt.
Der neue Farbstoff bildet ein schwärzliches Pulver, das sich in Wasser mit violettblaiier Farbe löst und Wolle aus saurem Bade in braunvioletten Farbtönen färbt, welche durch Nachchromieren in ein hervorragend licht-, walk- und pottingechtes grünstichiges Tief schwarz übergehen.
Beispiel: 24. Teile 1-Amiclo-5-oxyriaphtalin-7-sulfo- säure werden in 150 Teilen Wasser mit 10 Teilen Calciumliydroxyd warm gelöst und hei 0 bis 5 mit der eben kongosauer ge stellten wässerigen Suspension der Diazover- bindiin.tr, Hergestellt aus 15,5 Teilen 4-Nitro- 2-a.miclolihenol, 15 Teilen Salzsäure und 7 Teilen Nitrit in<B>300</B> Teilen Wasser, ver setzt.
Die sofort eintretendo Kupplung ist in etwa 20 Minuten unter Bildung eines .dun- keln Farbstoffbreies fertig. Der Farbstoff kann durch Ansäuern undFiltrieren, oder nach abstumpfen der geringen Menge freien Ätz- kalkes durch heisses Umsetzen mit Soda., Filtrieren vom Calciumcarbonat und Aassal zen des Filtrates mit Kochsalz gewonnen werden.
Process for the production of a post-chromium plating dye. It has been found that a new post-chromium plating dye can be produced by coupling diazotized 4-nitro-2-aminophenol with 1-amino-5-oxynaphthalene-7-sulfonic acid in the presence of calcium hydroxide.
The new dye forms a blackish powder that dissolves in water with a violet-blue color and dyes wool from an acidic bath in brown-violet hues, which, after being chromed, turn into a greenish deep black, which is extremely light, millfast and potting.
Example: 24th parts of 1-amiclo-5-oxyriaphthalene-7-sulfonic acid are dissolved in 150 parts of water with 10 parts of calcium hydroxide and hot 0 to 5 with the aqueous suspension of the diazo bindiin.tr which has just been prepared from 15.5 parts of 4-nitro-2-a.miclolihenol, 15 parts of hydrochloric acid and 7 parts of nitrite in 300 parts of water.
The coupling, which occurs immediately, is ready in about 20 minutes with the formation of a dark pigment paste. The dye can be obtained by acidification and filtration or, after the small amount of free quick lime has been blunted, by hot reaction with soda, filtration of the calcium carbonate and carrion salts of the filtrate with common salt.
