AISERLICHESEVERYTHING
PATENTAMT.PATENT OFFICE.
Die seither sich im Händel befindenden schwarzen Azofarbstoffe für Wolle sind durchweg Disazofarbstoffe, sie besitzen zwar ein mangelhaftes Egalisierungsvermögen, aber durch ihren verhältnismäßig niedrigen Preis und einige Vorteile in den Echtheitseigenschaften haben sie doch allgemeine Verbreitung in der Wollfärberei erlangt.The black azo dyes for wool that have been in the trade since then are all Disazo dyes, they have a poor leveling ability, but through have their relatively low price and some advantages in the authenticity properties after all, it has become widespread in wool dyeing.
Es sind nun in letzter Zeit mehrfach Verfahren bekannt geworden, um mit egalisierenden Monoazofarbstoffen schwarze Färbungen auf Wolle zu erzielen, so durch die Patentschriften 90770 und 109932. Die zu diesem Zweck hergestellten Monoazokörper haben aber mit dem zum Teil aus den billigsten Materialien der Teerfarbenindustrie hergestellten Disazowollschwarz nicht in erfolgreiche Konkurrenz treten können. Es wurde nun gefunden, daßv man aus diazot. 6-Nitro-2-amido-1 -phenol-4-sulfosäure einerseits und ß-Naphtol andererseits einen Monoazokörper erhält, welcher Wolle direkt tiefviolett anfärbt und durch Chromieren in eine schwarze Färbung übergeführt werden kann, welche vortreffliche Eigenschaften besitzt.There are now several methods have recently become known to achieve black dyeing on wool with leveling monoazo dyes, for example through the patents 90770 and 109932. The monoazo bodies produced for this purpose, however, have disazo wool black with the disazo wool, some of which are made from the cheapest materials in the tar color industry cannot compete successfully. It has now been found that v one from diazot. 6-nitro-2-amido-1-phenol-4-sulfonic acid on the one hand and ß-naphthol on the other hand receive a monoazo body which directly dyes wool deep purple and can be converted into a black coloration by chroming, which has excellent properties.
Die Farbkraft ist eine bedeutende, Wasser-, Säure-, Alkali-, Licht-, Reib- und Schwefelechtheit ist eine vorzügliche, die Walk- und Dekaturechtheit ist vollkommen und das Egalisierungsvermögen ein ausgezeichnetes, indem selbst minderwertiges loses Wollmaterial vollkommen gleichmäßig angefärbt wird.The color strength is a significant, water, acid, alkali, light, rub and sulfur fastness is an excellent one, the fulling and decal fastness is perfect and the equalizing ability an excellent one, in that even poor quality loose wool material is dyed completely evenly.
Die wertvollen Eigenschaften des ß-Naphtolfarbstoffes, insbesondere seine tiefe violette Nuance waren durchaus nicht vorauszusehen.The valuable properties of the ß-naphthol dye, in particular its deep purple nuance was by no means foreseeable.
In der Tat liefern die Sulfosäuren des ß-Naphtols, welche in Kombination mit Diazoverbindungen im allgemeinen blauere Nuancen ergeben als ß-Naphtol selbst, in Kombination mit diazot. 6-Nitro-2-amido-phenol-4-sulfosäure minderwertigere Produkte; auch der Ersatz der 6-Nitro-2-amido-phenol-4-sulfosäure durch eine isomere Nitroamidophenolsulfosäure führt zu wenig' brauchbaren Resultaten.In fact, the sulfonic acids of ß-naphthol, which in combination with diazo compounds generally bluer nuances result than ß-naphtol itself, in combination with diazot. 6-nitro-2-amido-phenol-4-sulfonic acid inferior products; also the replacement of 6-nitro-2-amido-phenol-4-sulfonic acid by an isomeric nitroamidophenol sulfonic acid leads to poorly useful results.
Die Darstellung des neuen Farbstoffes geschieht beispielsweise wie folgt:The representation of the new dye is done, for example, as follows:
3,84 kg nitroamidophenolsulfosaures Natron werden in 100 1 Wasser gelöst, 3,30 1 Salzsäure von 30 Prozent zugesetzt und bei 10 bis 150 diazotiert. Die gelbgefärbte Diazolösung läßt man einfließen in eine kalt gehaltene Lösung von 0,70 kg Ätznatron, 3,30 kg calc. Soda und 2,20,kg ß-Naphtol in 50 1 Wasser. Die Farbstoff bildung tritt sofort ein, indem sich die Flüssigkeit blauviolett färbt. Der Farbstoff scheidet sich zum größten Teil als grünlich bronzefarbener Niederschlag ab. Man erwärmt auf etwa 450 und rührt einige Stunden bei dieser Temperatur. Durch Zusatz von wenig Salz wird auch der kleine in Lösung befindliche Teil des Farbstoffes abgeschieden.3.84 kg nitroamidophenolsulfosaures sodium are dissolved in 100 1 water, 3.30 1 of 30 percent hydrochloric acid was added and diazotised at 10 to 15 0th The yellow colored diazo solution is allowed to flow into a cold solution of 0.70 kg of caustic soda, 3.30 kg of calc. Soda and 2.20 kg ß-naphtol in 50 l of water. The dye is formed immediately as the liquid turns blue-violet. Most of the dye separates out as a greenish bronze-colored precipitate. The mixture is heated to about 45 0 and stirred for several hours at this temperature. By adding a little salt, the small part of the dye that is in solution is also separated out.
In trockener Form bildet der Farbstoff ein braunes bronzeglänzendes Pulver, welches sich in Wasser mit violetter Farbe löst, die durch Ammoniak um wenig verändert wird; Alkohol löst nur geringe Mengen mit blauvioletter Farbe. Die Lösung des Farbstoffes in konz. Schwefelsäure ist bläulich rot; durch Wasserzusatz wird der Farbstoff als ziegelroter Niederschlag gefällt.In dry form, the dye forms a brown, bronze-shimmering powder, which is Dissolves in water with a purple color, which is slightly changed by ammonia; alcohol dissolves only small amounts with a blue-violet color. The solution of the dye in conc. Sulfuric acid is bluish red; the addition of water turns the dye into a brick-red precipitate pleases.
