Description

Verfahren zur Herstellung von Wollfarbstoffen Es wurde gefunden, daßesgelingt, i-Aminoqi-?bromanthrachinon;-2-@sulfOnSäUre mit Diaminoarylmonosulfonsäuren (mit Ausnahme von p-Phenylendiaminmonosulfonsäure) zu Aminoderivaben der i-Amino-q.-(sulfoarylido)-anthrachinon-2-sulfonsäure -zu kondensieren, indem man die Komponenten in wäßriger Lösung in Gegenwart eines säurebindenden Mittels und eines Katalysators, wie z. B. Kupfer,, erhitzt. Die zur Verwendung gelangenden Diaminoarylmonosulfonsäuren müssen mindestens eine freie Aminogruppe enthalten, während die andere alkyliert, aralkyliert oder ä`ryliert sein kann.Process for the production of wool dyes It has been found that i-Aminoqi-? bromoanthraquinone; -2- @ sulfonic acid with diaminoarylmonosulfonic acids (with Exception of p-phenylenediamine monosulfonic acid) to amino derivatives of i-amino-q .- (sulfoarylido) -anthraquinone-2-sulfonic acid -to condense by placing the components in aqueous solution in the presence of a acid binding agent and a catalyst, such as. B. copper ,, heated. The for Diaminoarylmonosulfonic acids used must have at least one free Contain amino group, while the other is alkylated, aralkylated or a`rylated can be.

Die Möglichkeit, diese Kondensationsprodukte herzustellen, ist überraschend, da die einfachen Aminoarylsulfonsäuren unter den gleichen Bedingungen sich nicht mit i-Amino-¢-bromanthrachinon-2-sulfonsäure zu den entsprechenden i-Amino-q.-sulfo.arylidoanthrachinon-2-sulfonsäuren kondensieren lassen. Die erhaltenen Kondensationsprodukte sind wertvolle Farbstoffe, die Wolle aus saurem Bade in blauen bis grauen bis grünen Tönen anfärben und vorzügliche Echtheitseigenschaften aufweisen. Von den für das Verfahren verwendbaren Diaminoarylmonosulfansäuren seien beispielsweise folgende genannt: Benzidinmonosulfonsäuren, Aminodiphenylaminsulfonsäuren, Cycloliexylphenylendiaminsulfonsäuren usw.The possibility of making these condensation products is surprising since the simple aminoarylsulfonic acids do not differ under the same conditions with i-amino [-bromoanthraquinone-2-sulfonic acid] to give the corresponding i-amino-q.-sulfo.arylidoanthraquinone-2-sulfonic acids let condense. The condensation products obtained are valuable dyes, dye the wool from an acid bath in blue to gray to green tones and make excellent colors Have authenticity properties. Of the diaminoarylmonosulfanic acids that can be used for the process the following may be mentioned, for example: benzidine monosulfonic acids, aminodiphenylamine sulfonic acids, Cycloliexylphenylenediaminesulfonic acids etc.

Beispiel i 5o kg i-amino-¢-bromanthrachinon-2-sulfonsaures Natrium werden mit 5o kg Benzidin-3-sulfonsäure bei Gegenwart von 5o kg Soda und 5 kg Kupfervitriol in- 3ooo 1 Wasser durch mehrstündiges Rühren bei 7o bis 8o° kondensiert. Die stark grünblau gefärbte Lösung wird ausgesalzen und das ausgeschiedene Reaktionsprodukt nochmals in 3ooo 1 Wasser angeschlämmt bzw. gelöst. Der reine Farbstoff läßt sieh durch Zusatz von 2o kg konzentrierter Salzsäure vollständig ausfällen und mit Wasser auswaschen. Bei Gegenwart von schwachen Alkalien, wie Soda, löst @er sich leicht wieder in Wasser auf und ergibt aus essigsaurem Bade auf Wolle eine klare grünblaue Nuance, die neben einer vorzüglichen Wasch- und Schweißechtheit auch eine gute Lichtechtheit ,aufweist. Die Lösungsfarbe in konzentrierter Schwefelsäure ist bräunlich, auf Zusatz von Päraformaldehyd wird sie blau. Beispiel 2 5o kg i-amino-q.-bromanthrachiiion-2-sulfonsaures Natrium werden mit 5o kg q. # q.'-diaminodiphenylamin - 2 - sulfonsaurem Natrium nach. den Angaben des Beispiels i kondensiert. Der durch mfällung-_mit Salzsäure gereinigte Farbstoff döst :sich--auch öle Zusatz von -.Al r= kauen sehr: lgicht in %per und färtt -.aus saurem, am besten essigsaurem Bade Wolle in graublauen Tönen an, die ausgezeichnete Echtheit-en besitzen. Die Lösung in konzen- trierter Schwefelsäure ist schwach blau ge- färbt, nach Zusatz von Paraformaldehyd wird sie grün. Beispiel 3 5okg i-amino-q.-bromantliraclii.non-a-sulfOn- saures Natrium werden mit 5o kg i-cyclo- hexylamino-q.-aminobenzol-z-sulfonsaur@em Na- trium entsprechend den Angaben des Bei- spiels i kondensiert. Der leicht durch, Aus- salzen rein zu erhaltene Farbstoff löst sich in konzentrierter Schwefelsäure mit schwach grünlichblauer Farbe, die aber nach Zusatz von Paraformaldehyd in ein tiefes Grün umschlägt. Wolle wird aus essigsaurem oder schwefelsaurem Bade in grünstickig blauen Tönen angefärbt.EXAMPLE I 50 kg of i-amino- [bromoanthraquinone-2-sulfonic acid sodium are condensed with 50 kg of benzidine-3-sulfonic acid in the presence of 50 kg of soda and 5 kg of vitriol in 3,000 1 of water by stirring for several hours at 70 to 80 °. The strongly green-blue colored solution is salted out and the precipitated reaction product is slurried or dissolved again in 3,000 l of water. The pure dye can be completely precipitated by adding 20 kg of concentrated hydrochloric acid and washed out with water. In the presence of weak alkalis, such as soda, it dissolves again easily in water and, from an acetic acid bath on wool, gives a clear green-blue shade which, in addition to excellent wash and perspiration fastness, also has good lightfastness. The color of the solution in concentrated sulfuric acid is brownish; when paraformaldehyde is added, it turns blue. Example 2 50 kg of i-amino-q.-bromoanthrachiiion-2-sulfonic acid sodium are mixed with 50 kg q. # q .'- diaminodiphenylamine - 2 - sodium sulfonic acid after. the details of example i condensed. Purified by precipitation with hydrochloric acid Dye dozes: itself - also oils. Addition of -.Al r = chew a lot: lgout in% per and hardens sour, preferably acetic, bath wool in gray-blue tones that are excellent Own authenticity. The solution in concentrated sulfuric acid is slightly blue colors after the addition of paraformaldehyde they green. Example 3 5okg i-amino-q.-bromantliraclii.non-a-sulfOn- acid sodium is mixed with 50 kg of i-cyclo- hexylamino-q.-aminobenzol-z-sulfonsaur@em Na- trium according to the information provided by the game i condensed. Who easily through, out salt pure to obtain dye dissolves in concentrated sulfuric acid with a pale greenish-blue color, which turns into a deep green after the addition of paraformaldehyde. Wool is dyed from acetic acid or sulfuric acid bath in greenish blue tones.
