Es wurde gefunden, daß wertvolle wasch-, walk- und dekaturechte schwarze Wollfarbstoffe gewonnen werden, wenn peri-Aminonaphtolsulfosäuren, die sich zweimal mit Diazoverbindungen zu vereinigen vermögen, zuerst in saurer Lösung mit einer beliebigen Diazoverbindung und darauf in alkalischer Lösung mit der Diazoverbindung des 4-Chlor-2-aminophenolbenzyläthers, der in der PatentschriftIt has been found that valuable black wool dyes that are washable, milled and decade-fast obtained when peri-aminonaphthol sulfonic acids, which are twice with diazo compounds able to combine, first in acidic solution with any diazo compound and then in alkaline solution with the diazo compound of 4-chloro-2-aminophenol benzyl ether, that in the patent specification
ίο 142899 beschrieben ist, gekuppelt werden. Die so erhaltenen Farbstoffe färben Wolle in saurem Bade in schwarzen Tönen an. Die Färbungen sind wasch-, walk- und dekaturecht. Diese Eigenschaften bedingen einenίο 142899 is described, must be coupled. the The dyes obtained in this way dye wool in an acidic bath in black tones. The colors are washable, milled and decorative. These qualities require you
ig großen technischen Fortschritt.ig great technical progress.
Die neuen Farbstoffe zeigen im besonderen eine wesentlich bessere Waschechtheit als die bekannten analogen Kombinationsprodukte der Patentschriften 65651, 81241 und 214496. Die Echtheitseigenschaften werden durch die Einführung des 4-Chlor-2-aminophenolbenzylätherrestes bedeutend verbessert.The new dyes show in particular a much better wash fastness than that known analog combination products of patents 65651, 81241 and 214496. The Fastness properties are enhanced by the introduction of the 4-chloro-2-aminophenolbenzylätherrestes significantly improved.
Namentlich wird die Waschechtheit, die bei den bekannten Handelsmarken vom Naphtolblauschwarztypus als für die heutigen Verhältnisse nicht mehr genügend bekannt ist, derartig gesteigert, daß dadurch ein wesentlicher technischer Fortschritt erzielt wird.In particular, the wash fastness is that of the well-known trademarks of the naphtol blue black type than is no longer sufficiently known for today's conditions, such increased so that a significant technical advance is achieved.
13,8 kg p-Nitranilin werden in bekannter Weise diazotiert und in mineralsaurer Lösung mit 34 kg des frisch gefällten sauren Natriumsalzes der ι · 8 · 3 · 6-Aminonaphtoldisulfosäure vereinigt. Wenn nach längerem Rühren die Kupplung beendet ist, wird mittels Soda oder Natronlauge neutralisiert und nach Zusatz von überschüssiger Soda eine aus 27 kg salzsaurem 4-Chlor-2-aminophenolbenzyläther, 20 kg Salzsäure von 30 Prozent und 7 kg Natriumnitrit in etwa 300 1 Wasser erhaltene Diazolösung zulaufen gelassen.13.8 kg of p-nitroaniline are known in Way diazotized and in mineral acid solution with 34 kg of the freshly precipitated acid sodium salt the ι · 8 · 3 · 6-aminonaphthol disulfonic acid united. When the coupling is complete after prolonged stirring, soda or Sodium hydroxide solution is neutralized and, after the addition of excess soda, one from 27 kg of hydrochloric acid 4-chloro-2-aminophenol benzyl ether, 20 kg hydrochloric acid of 30 percent and 7 kg sodium nitrite run in diazo solution obtained in about 300 l of water.
Der Farbstoff bildet sich sofort und scheidet sich größtenteils ab. Nach einiger Zeit wird gelinde erwärmt und nach Zusatz von wenig Kochsalz nitriert. Der Farbstoff färbt Wolle in saurem Bade violettschwarz.The dye forms immediately and largely separates out. After some time is gently heated and nitrated after adding a little table salt. The dye stains Wool in an acidic bath purple-black.
