Description

Verfahren zur Herstellung von Schwefelfarbstoffen Zusatz zum Patent 653 675 Gegenstand des Patents 653 675 ist ein Verfahren zur Herstellung von Schwefelfarbstoffen, das darin besteht, daß man Dekacyclen, gegebenenfalls ?i Anwesenheit von Metallsalzen, mit schwefelnden Mitteln behandelt und die Rohschmelze in bekannter Weise aufarbeitet. Man erhält dabei rotbraune Farbstoffe von besonderer Klarheit und einem bisher nicht erreichten Rotstich der mit ihnen erzielbaren Färbungen.Process for the production of sulfur dyes. Patent addition 653 675 The subject of patent 653 675 is a process for the production of sulfur dyes, that consists in the fact that one decacycles, if necessary? i presence of metal salts, treated with sulphurizing agents and worked up the raw melt in a known manner. This gives red-brown dyes of particular clarity and one not so far achieved red tint of the dyeings that can be achieved with them.

Wie nun weiter gefunden wurde, gelangt man zu gleichfalls wertvollen Schwefelfarbstoffen von gelbbrauner bis braunoliver Tönung ihrer Färbung, wenn man statt des Dekacyclens seine Nitroverbindungen der Schwefelung unterwirft. Durch Nachbehandlung der Färbungen mit Alkylierungsmitteln wird .ein lebhafterer und mit Kupfersülfatchromkali ein grünerer Farbton erhalten.As has now been found, one arrives at equally valuable ones Sulfur dyes from yellow-brown to brown-olive hue of their coloration, if one instead of decacycle, subjects its nitro compounds to sulphurization. By Post-treatment of the dyeings with alkylating agents becomes .a livelier and with Copper sulphate chromium potash obtained a greener shade.

Beispiel 1 i oo Teile Trinitr odekacyclen, das man durch Einwirkung von Salpetersäure (D= 1.q.2) ,auf Dekacyclen bei o bis 18° herstellen kann, werden mit 3oo Teilen kristallisiertem Natriumsulfid und Zoo Teilen Schwefel unter Rühren etwa 26 Stunden bei 118° am Rückfllußkühler gekocht. Die Temperatur der Schmelze wird nun unter Abdestillieren von Wasser langsam auf 17o° gesteigert und etwa, 18 Stunden auf dieser Höhe gehalten. Die Farbstoffrohschmelze kann als solche zum Ausfärben verwendet werden oder aber sie wird mit Natriumsulfid in Wasser gelöst. worauf der Farbstoff in bekannter Weise abgeschieden wird. In diesem Falle erhält man etwa 155 Teile Farbstoff, der Baumwolle in gelbbraunen Tönen von guter Echtheit anfärbt.Example 1 100 parts Trinitr odekacyclen, which one by action of nitric acid (D = 1.q.2), can be produced on decacycles at 0 to 18 ° with 300 parts of crystallized sodium sulfide and zoo parts of sulfur with stirring boiled for about 26 hours at 118 ° on a reflux condenser. The temperature of the melt is now slowly increased to 170 ° while distilling off water and about, 18 Hours at this height. The raw dye melt can be used as such for coloring can be used or it is dissolved in water with sodium sulfide. what the Dye is deposited in a known manner. In this case you get about 155 parts of dye that dyes cotton in yellow-brown shades of good fastness.

Beispiel 2 1 oo Teile H:exanitrodekacyclen, durch Einwirkung von Salpetersäure der Dichte 1,5 auf Dekacyclenbeietwa 2o°;erhalten, werden unter Rühren in eine aus 35o Teilen kristallisiertem l,Tatriumsulfid und 15o Teilen Schwefel hergestellte Polysulfidlösung eingetragen und 24 Stunden bei einer Kochtemperatur von 115° am Rückflußkühler erhitzt. Das Reaktionsgemisch wird dann langsam zur Trockene eingedampft und :etwa 2o Stunden bei 22o nachgebacken. Man löst die erhaltene Rohschmelze in bekannter Weise in Wasser und fällt den Farbstoff mit Säure. Die Ausbeutc beträgt 105 bis i io Teile Farbstoff. Er färbt Baumwolle in braunen Tönen, die neben sonstigen guten Echtheitseigenschaften besonders eine gute Lichtechtheit aufweisen.Example 2 100 parts of H: exanitrodecacycles, by the action of nitric acid with a density of 1.5 to decacycles at about 2o °; are poured into an off with stirring 35o parts of crystallized oil, sodium sulfide and 150 parts of sulfur Polysulfide solution entered and 24 hours at a cooking temperature of 115 ° am Heated reflux condenser. The reaction mixture is then slowly evaporated to dryness and: baked for about 20 hours at 22o. The raw melt obtained is dissolved in known way in water and precipitates the dye with acid. The yield is 105 to 10 parts dye. He dyes cotton in brown tones, in addition to others have good fastness properties, especially good lightfastness.
