Patentiert im Deutschen Reiche vom 11. Februar 1910 ab.Patented in the German Empire on February 11, 1910.
Es wurde gefunden, daß durch Kombination der Tetrazo verbindung aus 2 · 6-Toluylendiamin-4-sulfosäure mit einem Molekül 2 · 8-Aminonaphtol-6-sulfosäure in saurer Lösung und einem Molekül eines m-Diamins oder mrAminophenols Disazofarbstoffe entstehen, die Baumwolle in rötlichen Tönen anfärben, die beim Nachbehandeln mit diazotiertem p-Nitranilin in lebhaftes gelbliches bis rötliches Braun übergehen. Diese entwickelten Färbungen sind trotz der Anwesenheit von zwei Sulfogruppen in dem verhältnismäßig kleinen Farbstoffmolekül vorzüglich waschecht und lassen sich sehr schön weiß ätzen.It has been found that by combining the tetrazo compound of 2 · 6-toluylenediamine-4-sulfonic acid with a molecule of 2 · 8-aminonaphthol-6-sulfonic acid in acidic solution and a molecule of an m-diamine or m r aminophenol disazo dyes are formed Dye cotton in reddish tones, which turn into a lively yellowish to reddish brown when treated with diazotized p-nitroaniline. In spite of the presence of two sulfo groups in the relatively small dye molecule, these colorations developed are extremely washable and can be very nicely etched white.
22,4 Teile 2 · 6-toluylendiamin-4-sulfosaures Natron werden in 300 Teilen Wasser gelöst und unter guter Eiskühlung mit 14 Teilen Natriumnitrit und 65 Teilen Salzsäure 200 Be. diazotiert. Hierzu läßt man eine mit Soda neutralisierte, gut gekühlte Lösung von 23,9 Teilen 2 · 8-Aminonaphtol-6-sulfosäure fließen. Nach Bildung des Zwischenproduktes fügt man eine Lösung von 11 Teilen m-Phenylendiamin hinzu und rührt ungefähr 12 Stunden. Dann wird mit Soda neutralisiert, auf 70° erwärmt, mit Salz gefällt und in üblicher Weise fertig gemacht. Der Farbstoff bildet ein dunkelbraunes Pulver und löst sich in konzentrierter Schwefeisäure rötlichbordeaux, in Wasser bräunlichorange auf. Die wäßrige Lösung wird durch .Natronlauge nicht verändert; durch Salzsäure wird daraus der Farbstoff in rötlichbraunen Flocken gefällt. Er erzeugt auf Baumwolle rote Nuancen, die durch Nachbehandlung mit diazotiertem p-Nitranilin in ein sehr waschechtes rötliches Braun übergehen, das sich sehr schön weiß ätzen läßt.22.4 parts of 2 · 6-tolylenediamine-4-sulfonic acid are dissolved in 300 parts of water and mixed with 14 parts of sodium nitrite and 65 parts of hydrochloric acid with 20 ° Be. diazotized. To this end, a well-cooled solution of 23.9 parts of 2 · 8-aminonaphthol-6-sulfonic acid, neutralized with soda, is allowed to flow. After formation of the intermediate product, a solution of 11 parts of m-phenylenediamine is added and the mixture is stirred for about 12 hours. Then it is neutralized with soda, heated to 70 °, precipitated with salt and made ready in the usual way. The dye forms a dark brown powder and dissolves reddish-burgundy in concentrated sulfuric acid and brownish-orange in water. The aqueous solution is not changed by sodium hydroxide solution; hydrochloric acid precipitates the dye in reddish-brown flakes. He creates red nuances on cotton, which after treatment with diazotized p-nitroaniline turn into a very washable reddish brown, which can be etched very nicely white.
Mit anderen m-Diaminen, z. B. m-Toluylendiamin, wird die Kombination in analoger Weise ausgeführt. Der Farbstoff mit m-Aminophenol an zweiter Stelle liefert bei Nachbehandlung mit p-Nitrodiazobenzol gelbstichigere Nuancen.With other m-diamines, e.g. B. m-tolylenediamine, the combination is carried out in an analogous manner. The dye with m-aminophenol in second place, after-treatment with p-nitrodiazobenzene gives a more yellowish tinge Nuances.
