Description
Verfahren zur Darstellung eines Küpenfarbstoffes der Anthrachinonreihe. Im Hauptpatent 101169 ist ein- Verfahren zur Darstellung eines wertvollen gelben Küpen- farbstoffes beschrieben, nach dem man auf 1-Merlzapto-2-aminoanthracbiiion ein solches Derivat der Terephtalsäure einwirken lässt, das leicht in die Terephtalsäure überführbar ist, wie zum Beispiel die Säurehalogenide, die entsprechenden co-Tetra- beziehungsweise Hexahalogenmethylderivate,
den Dialdehyd etc.
Es wurde nun gefunden, dass man zu dem gleichen Farbstoff gelangt, wenn man 1-Halo- gen-2-aminoanthrachinon verwendet, auf dieses ein Terephtalsäurederivat der genannten Art einwirken lässt und das zunächst erhaltene Zwischenprodukt mit einer Schwefel abge benden Substanz, z. B. Schwefel, Schwefel natrium, Natriumpolysulfid, Kaliumxantho- genat etc., behandelt. Man kann dabei in Gegenwart von Kondensationsmitteln arbeiten.
<I>Beispiel 1:</I> 10 Teile des Einwirkungsproduktes von 1 Mol. Terephtaloylchlorid auf 2 Hol. 1-Chlor- 2-amirioaiithrachinon, 40 Teile kristallisiertes Schwefelnatrium, 10 Teile Schwefel,<B>100</B> Teile Wasser und 100 Teile Alkohol werden in einem eisernen Druckgefäss mit Rührer drei Stunden auf<B>180-2000</B> erhitzt. Nach be endeter Reaktion wird der Alkohol abdestil- liert und zurückgewonnen.
Die Reaktions masse wird mit Wasser versetzt, der unlös liche Farbstoff abfiltriert, ausgewaschen und gewünschtenfalls durch Behandeln mit Natri- umhypochloritlösung weiter gereinigt. Er ist dann direkt zum Färben verwendbar. Er ist identisch mit dem aus 1-Merkapto-2-amino- anthrachinon gemäss Hauptpatent erhaltenen Farbstoff.
<I>Beispiel 2:</I> 5 Teile des Einwirkungsproduktes von 1 Mol. Terephtaloylchlorid auf 2 Hol. 1-Chlor- 2-aminoanthrachinon, 10 Teile wasserfreies Schwefelnatrium, 15 Teile Schwefel und 100 Teile Phenol werden 10-12 Stunden zum Sieden erhitzt. Der entstehende Farbstoff wird bei 70-80 abgesaugt und mit etwas Phenol und mit Wasser gewaschen. Der Farbstoff ist identisch mit dem näch Beispiel 1 erhal tenen.
Process for the preparation of a vat dye of the anthraquinone series. The main patent 101169 describes a process for the preparation of a valuable yellow vat dye, according to which one allows such a derivative of terephthalic acid to act on 1-merlzapto-2-aminoanthracbiiion, which can easily be converted into terephthalic acid, such as the acid halides, the corresponding co-tetra- or hexahalomethyl derivatives,
the dialdehyde etc.
It has now been found that the same dye is obtained if 1-halo-2-aminoanthraquinone is used, a terephthalic acid derivative of the type mentioned is allowed to act on this and the intermediate product initially obtained is treated with a sulfur-emitting substance, eg. B. sulfur, sodium sulfur, sodium polysulfide, potassium xanthogenate, etc., treated. You can work in the presence of condensing agents.
<I> Example 1: </I> 10 parts of the action product of 1 mol. Terephtaloyl chloride on 2 hol. 1-chloro-2-amirioaiithraquinone, 40 parts of crystallized sodium sulfur, 10 parts of sulfur, 100 parts of water and 100 parts of alcohol are heated to 180-2000 for three hours in an iron pressure vessel with a stirrer > heated. When the reaction has ended, the alcohol is distilled off and recovered.
The reaction mass is mixed with water, the insoluble dye is filtered off, washed out and, if desired, further purified by treatment with sodium hypochlorite solution. It can then be used directly for dyeing. It is identical to the dye obtained from 1-mercapto-2-amino-anthraquinone according to the main patent.
<I> Example 2: </I> 5 parts of the action product of 1 mol. Terephtaloyl chloride to 2 hol. 1-chloro-2-aminoanthraquinone, 10 parts of anhydrous sodium sulphide, 15 parts of sulfur and 100 parts of phenol are heated to the boil for 10-12 hours. The resulting dye is suctioned off at 70-80 and washed with a little phenol and with water. The dye is identical to the next Example 1 obtained.
