M 127676 KLASSE 22d. M 127676 CLASS 22d.
Durch energische Nitrirung von Diphenylamin entsteht das Hexanitrodiphenylamin (Dipikrylamin), dessen Natron- oder Ammonsalz als »Aurantia« eine Zeit lang in den Handel gebracht wurde (vergl. Beilstein, III. Auflage, Band 2, S. 340).Vigorous nitration of diphenylamine produces hexanitrodiphenylamine (dipikrylamine), its sodium or ammonium salt was marketed for a while as "Aurantia" (see Beilstein, III. Edition, Volume 2, p. 340).
Es wurde nun gefunden, dafs ein werthvoller, direkt färbender brauner Baumwollfarbstoff entsteht, wenn man die genannte Nitroverbindung mit Schwefel und Schwefelalkali erhitzt. ~It has now been found that a valuable, direct dyeing brown cotton dye arises when the aforementioned nitro compound is heated with sulfur and alkali sulfur. ~
250 Theile Schwefelnatrium werden in 100 Theilen Wasser gelöst und in diese Lösung bei 45 bis 500 50 Theile Hexanitrodiphenylamin allmählich eingetragen. Nach Beendigung der Reaction werden 100 Theile Schwefel zugegeben, die Masse aufgekocht, eingedickt und bei 1400 gebacken. Der so erhaltene Farbstoff kann direkt zum Färben verwendet werden.250 parts of sodium sulphide are dissolved in 100 parts of water and gradually introduced into this solution at 45 to 50 ° 50 parts of hexanitrodiphenylamine. After completion of the reaction, 100 parts of sulfur are added, boiled mass, concentrated and baked at 140 0th The dye thus obtained can be used directly for dyeing.
Der Farbstoff löst sich in Wasser mit brauner Farbe und wird aus dieser Lösung durch Salzsäure, Chlorammonium, Kochsalz u. s. w. in braunen Flocken gefällt. In concentrirter Schwefelsäure löst er sich mit gelbbrauner Farbe und fällt auf Zusatz von Wasser wieder aus.The dye dissolves in water with a brown color and is made from this solution by hydrochloric acid, Chlorammonium, table salt, etc. precipitated in brown flakes. In concentrated sulfuric acid it dissolves with yellow-brown Color and precipitates again when water is added.
Er färbt ungeheizte Baumwolle direkt in braunen Tönen an, welche aufserordentlich widerstandsfähig gegen Seife, Säuren u. s. w. sind und eine hervorragende Lichtechtheit besitzen. Durch Nachbehandeln mit Chromalaun oder mit Kupfervitriol, ebenso mit Chromkali, Kupfervitriol und Essigsäure findet eine Vertiefung des Farbtones statt. Durch Einwirkung von Chromkali und Schwefelsäure oder von Wasserstoffsuperoxyd werden die Töne etwas heller.He stains unheated cotton directly in brown tones, which are extraordinary are resistant to soap, acids, etc. and have excellent lightfastness. After treatment with chrome alum or with copper vitriol, also with chrome potassium, Vitriol and acetic acid deepen the color tone. By exposure from potassium chromium and sulfuric acid or from hydrogen peroxide the tones become somewhat brighter.
Die Färbungen liefern durch Kuppeln mit Diazoverbindungen auf der Faser und ebenso durch Diazotiren und Kuppeln neue, sehr werthvolle, gleichfalls aufserordentlich echte Nuancen.The colorations are provided by coupling with diazo compounds on the fiber and as well new, very valuable, and likewise extraordinarily real, through diazotires and domes Nuances.
