Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen, gleichzeitig Chrom- und schwefelhaltigen Farb stoff erhält, wenn man die Chromverbindung des durch Kupplung der nitrierten Diazover- bindung der 1-Amino-2-oxynaphtalin-4-sulfo- säure und a-Naphthol und nachlierige Reduk tion der Nitrogruppe erhaltenen Azofarbstoffes mit Schwefel abgebenden Mitteln in Gegen wart von Äthylalkohol behandelt.
Der so erhaltene neue Farbstoff stellt ein blauschwarzes Pulver dar, er ist in Wasser unlöslich, in Schwefelalkalien mit blauer Farbe löslich und färbt aus schwefelnatrium- haltigem Bade Baumwolle iti grauen, gut wasch- und lichtechten Tönen an.
Beispiel: In 60 Teilen Ätzkali werden 72,5 Teile Chromhydroxydpaste mit 11,8 % Cra0s vor- sichtig gelöst. Dann werden 45 Teile des reduzierten Farbstoffes aus nitrierter Diazo- verbindung der 1.2-Aminonaphthol-4-sulfo- säure und a-Naphthol eingetragen.
Die dicke Masse wird 16 Stunden bei 75-80 0 gerührt, wonach die fertige Chromverbindung durch Verdünnen, Neutralstellen mit verdünnter Schwefelsäure und Aussalzen abgeschieden wird.
55 Teile dieses getrockneten Farbstoffes trägt man in eine alkoholische Polysulfid lösung ein, hergestellt aus 120 Teilen kalzi- niertem Schwefelnatrium, 96 Teilen Schwefel und 400 Teilen Alkohol. Die Masse wird 110 Stunden in einem mit Rückfluss ver- sehenen Gefäss gekocht, dann wird die Haupt menge des Alkohols abdestilliert und der Schwefelfarbstoff durch Verdünnen mit einer 20 % Kochsalz enthaltenden wässerigen Lö sung gefällt.
Er wird hierauf filtriert, mit einer Kochsalzlösung von 3 % gewaschen und getrocknet.
Process for the production of a new dye. It has been found that a new, at the same time chromium and sulfur-containing dye is obtained if the chromium compound of the 1-amino-2-oxynaphthalene-4-sulfonic acid and α-naphthol and subsequent ones is obtained by coupling the nitrated diazo compound Reduction of the nitro group obtained azo dye with sulfur-releasing agents in the presence of ethyl alcohol treated.
The new dye obtained in this way is a blue-black powder, it is insoluble in water, soluble in alkaline sulfur with a blue color, and from bath cotton containing sulfur sodium it stains gray, washable and lightfast shades.
Example: 72.5 parts of chromium hydroxide paste with 11.8% CraOs are carefully dissolved in 60 parts of caustic potash. Then 45 parts of the reduced dye from nitrated diazo compound of 1,2-aminonaphthol-4-sulfonic acid and α-naphthol are introduced.
The thick mass is stirred for 16 hours at 75-80 °, after which the finished chromium compound is deposited by dilution, neutralization with dilute sulfuric acid and salting out.
55 parts of this dried dye are introduced into an alcoholic polysulphide solution made from 120 parts of calcined sodium sulphide, 96 parts of sulfur and 400 parts of alcohol. The mass is boiled for 110 hours in a refluxing vessel, then most of the alcohol is distilled off and the sulfur dye is precipitated by dilution with an aqueous solution containing 20% sodium chloride.
It is then filtered, washed with a 3% saline solution and dried.
