Description

Verfahren zur Darstellung von schwefelhaltigen Baumwollfarbstoffen. Zusatz zum Patent 399909 Es wurde gefunden, daß schwefelhaltige Baumwollfarbstoffe. die den in dem Hauptpatent 399909 beschriebenen ähnlich sind, erhalten werden, wenn man Halogenchinone mit o-Nitroarylmerkaptanen und deren Äquivalenten zur Reaktion bringt und die so erhaltenen Körper oder deren Reduktionsprodukte einer Behandlung mit Polysulfiden unterwirft.Process for the preparation of sulfur-containing cotton dyes. Addendum to Patent 399909 It has been found that sulfur-containing cotton dyes. similar to those described in main patent 399909 can be obtained when one haloquinones with o-nitroaryl mercaptans and their equivalents for the reaction brings and the bodies obtained in this way or their reduction products to a treatment Subjected with polysulfides.

Beispiel. 31 Teile o-ol-Dinitrodiphenyldisulfid werden nach der Methode von Brand, Ber. 42, ?.465, zu o-Nitrothiophenol reduziert. In die erhaltene, mit Wasser verdünnte Lösung des Nitrothiophenolnatriumsalzes werden 25 Teile Chloranil gebracht. Unter Rühren und Erwärmen am Rückflußkühler tritt Reaktion ein. Der ausgeschiedene Körper wird abgesaugt und mit Wasser gewaschen. Das erhaltene graue Pulver ist mit Hvdrosulfit und Alkali reduzierbar und färbt aus dieser Küpe die Faser violettbraun an.Example. 31 parts of o-ol-Dinitrodiphenyldisulfid are according to the method von Brand, Ber. 42,? .465, reduced to o-nitrothiophenol. In the received, with Water-diluted solution of the nitrothiophenol sodium salt becomes 25 parts of chloranil brought. Reaction occurs with stirring and warming in the reflux condenser. The retired Body is sucked off and washed with water. The gray powder obtained is with Hydro sulfite and alkali are reducible and dyes the fibers violet-brown from this vat at.

2"q Teile dieses Reaktionsproduktes werden mit einer Lösung von 7,5 Teilen Schwefelnatrium kristallisiert und 5 Teilen Schwefel in 7,5 Teilen Wasser 2o bis 40 Stunden unter Rückfluß gekocht. Der gebildete Schwefelfarbstoff wird aus der mit Wasser verdünnten Reaktionsmasse, z. B. durch Ausblasen mit Luft, isoliert. Er färbt Baumwolle aus schwefelalkalischem Bade in rotbraunen Tönen an.2 "q parts of this reaction product are mixed with a solution of 7.5 Parts of sodium sulfur crystallize and 5 parts of sulfur in 7.5 parts of water Boiled under reflux for 20 to 40 hours. The sulfur dye formed becomes off the reaction mass diluted with water, e.g. B. by blowing with air, isolated. He dyes cotton from a sulfur-alkaline bath in red-brown tones.

Das Verfahren ist nicht auf die angegebenen Mengenverhältnisse und Zeitdauer beschränkt Z. B. wird ein ganz ähnlicher Farbstoff beim Zusammenbringen von 15,5 Teilen o-ol-Dinitrodipllenyldisulfid mit 25 Teilen Chloranil nach obigem Beispiel und Schwefelung erhalten. Ebenso kann das Verhältnis von Schwefel zu Schwefelnatrium in weiten Grenzen geändert werden; auch kann die Reaktion unter Verwendung geeigneter Verdünnungsmittel und in geschlossenem Gefäß unter erhöhtem Druck .durchgeführt werden; ebenso läßt sich die Schmelze unter Zusatz von Metallen oder Metallsalzen ausführen.The procedure is not limited to the specified proportions and Time limited For example, a very similar dye will be used when combined of 15.5 parts of o-ol-dinitrodiplenyl disulfide with 25 parts of chloranil according to the above Example and sulfurization received. Likewise, the ratio of sulfur to sodium sulfur can be changed within wide limits; the reaction can also be carried out using suitable Diluent and in a closed vessel under increased pressure will; Likewise, the melt can be with the addition of metals or metal salts carry out.

PATENTANSPRUCH: `''eitere Ausbildung des durch Patent 3999o9 geschützten Verfahrens zur Darstellung schwefelhaltiger Baumwollfarbstoffe, dadurch gekennzeichnet, daß man an Stelle der dort genannten Kondensationsprodukte hier die Kondensationsprodukte aus Halogenchinonen mit o-Nitroarylmerkaptanen oder deren Äquivalenten oder die Mischung der Kondensationskomponenten mit Polysulfiden behandelt. PATENT CLAIM: `` '' Further development of the process protected by patent 3999o9 for the preparation of sulfur-containing cotton dyes, characterized in that instead of the condensation products mentioned there, the condensation products of haloquinones with o-nitroaryl mercaptans or their equivalents or the mixture of the condensation components with polysulphides are treated.
