Patentirt im Deutschen Reiche vom 13. September 1900 ab.Patented in the German Empire on September 13, 1900.
Es wurde gefunden, dafs man' durch Einwirkung von Schwefelalkalien auf diejenigen Verbindungen, welche entstehen, wenn man Schwefelwasserstoff in die erwärmte Lösung von Ci1 a3 - Dinitronaphtalin in concentrirter Schwefelsäure einleitet, dunkelgraue Baumwollfarbstoffe erhält. Anstatt Schwefelwasserstoff in die Lösung einzuleiten, kann man natürlich den Schwefehvasserstoff in der Lösung aus Schwefelmetall entwickeln.It has been found that by the action of alkaline sulfur on those compounds which are formed when hydrogen sulfide is introduced into the heated solution of Ci 1 a 3 - dinitronaphthalene in concentrated sulfuric acid, dark gray cotton dyes are obtained. Instead of introducing hydrogen sulphide into the solution, one can of course evolve the hydrogen sulphide in the solution from sulfur metal.
Man erhält aus dem C1 a3 - Dinitronaphtalin durch Umsetzung mit Schwefelwasserstoff in concentrirter Schwefelsäure — nach intermediärer Bildung des Naphtazarinzwischenproducts — Verbindungen, die verschieden sind, je nachdem man Schwefelsäure von verschiedener Concentration anwendet. Während in Schwefelsäure von 66° B. ein in Alkali so gut wie unlösliches Product entsteht, erhält man beim Arbeiten in Monohydratlösung eine Verbindung, die sich in Alkalien oder deren Carbonaten blau löst.From the C 1 a 3 dinitronaphthalene, by reaction with hydrogen sulphide in concentrated sulfuric acid - after the intermediate formation of the naphtazarin intermediate - compounds are obtained which differ according to the use of sulfuric acid of different concentration. While sulfuric acid of 66 ° B. produces a product which is practically insoluble in alkali, when working in monohydrate solution one obtains a compound which dissolves blue in alkalis or their carbonates.
Die Darstellung der neuen Baumwollfarbstoffe aus den Umsetzungsproducten des Ci1 a3 - Dinitronaphtalins durch Erhitzen mit Schwefelalkali kann mit oder ohne Zusatz von Chlorzink erfolgen, ohne dafs ein wesentlicher Unterschied in den Eigenschaften des entstehenden Farbstoffs sich bemerkbar macht.The preparation of the new cotton dyes from the reaction products of Ci 1 a 3 -dinitronaphthalene by heating with sulfur alkali can take place with or without the addition of zinc chloride, without any significant difference in the properties of the resulting dye being noticeable.
20 Th. des Umwandlungsproductes ' von K1 a3 - Dinitronaphtalin mit Schwefelwasserstoff in Schwefelsäure von 66° B. werden mit 50 Th. Schwefelnatrium, 20 Th. Schwefel und 10 Th. Chlorzink 6 Stunden bei 130 bis i6o° erhitzt. Die Schmelze ist eine blaugraue Masse, die sich mit blauer Farbe leicht in Wasser löst; sie kann direct als Farbstoff verwendet werden und erzeugt auf Baumwolle dunkelgraue Nuancen, welche unter Einwirkung von Kupfersalzen in Schwarz übergehen.20 th. Of the conversion product of K 1 a 3 - dinitronaphthalene with hydrogen sulfide in sulfuric acid of 66 ° B. are heated with 50 th. Sodium sulfur, 20 th. Sulfur and 10 th. Zinc chloride for 6 hours at 130 to 160 °. The melt is a blue-gray mass that easily dissolves in water with a blue color; it can be used directly as a dye and produces dark gray nuances on cotton which turn black under the action of copper salts.
Das Einwirkungsproduct von Schwefelwasserstoff auf Ct1 G3 - Dinitronaphtalin in Monohydrat liefert in gleicher Weise, auch wenn der Zusatz von Chlorzink unterbleibt, eine Farbstoffschmelze, die keine wesentlich verschiedenen Eigenschaften besitzt.The product of the action of hydrogen sulphide on Ct 1 G 3 - dinitronaphthalene in monohydrate provides in the same way, even if the addition of zinc chloride is omitted, a dye melt which does not have significantly different properties.
