Description
Verfahren zur Barstellung eines Küpenfarbstoffes der Anthrachinonreihe. Im Elauptpatent ist ein Verfahren zur Darstellung eines Küpenfarbstoffes beschrie ben, bei dem 2<B>.</B> 1-(N)-Anthrachinonakridon- 6-karbotisätirechlorid mit 1-Amiiio-4-methoxy- anthrachinon durch Erhitzen in einem Lö sungsmittel umgesetzt wird.
Es wurde nun gefunden, dass man in ganz analoger Weise einen Küpenfarbstoff von ähnlichen wertvollen Eigenschäften er halten kann, wenn man 2 Mol. 2<B>.<I>1-(S)-</I></B> Anthrachitiotithioxanthon-6-karbonsäurechlo- rid von der Formel
EMI0001.0015
mit<B>1</B> Mol. <B>1 .</B> 5-Diaminoanthrachiiion durch Erhitzen in einem Lösungsmittel kondensiert.
<I>Beispiel:</I> <B>1,6</B> Teile 2<B>.</B> 1-(S)-Ar)thriichltioi)thioxaii- thon-6-kai-bonsäurechlorid der oben ange gebenen Formel, erhältlich zum Beispiel aus 1-Chloranthraebiiion-6-karborisäLire durch Kon densation mit Thiosalieyisäure, Ringsühluss mit Schwefelsäure und Behandeln der er haltenen Karbonsäure mit Phosphorpenta- chlorid, werden in 20 Teilen Trichlorbenzol mit 0,4 Teilen<B>1 .</B> 5-Diaminoanthrachinon auf etwa<B>210-215 0 C</B> erhitzt,
bis die Farbstoff- bildung beendet ist. Der beim Erkalten ab geschiedene Farbstoff wird zweckmässig durch Behandeln mit Natriumhypochlorit gereinigt. Er färbt Baumwolle aus violetter Küpe rot braun.
Process for the preparation of a vat dye of the anthraquinone series. In the Elaupt patent, a process for the preparation of a vat dye is described in which 2 <B>. </B> 1- (N) -Anthraquinonakridon- 6-carbotisätirechlorid with 1-Amiiio-4-methoxy-anthraquinone by heating in a solvent is implemented.
It has now been found that a vat dye with similar valuable properties can be obtained in a completely analogous manner if one uses 2 mol. 2 <B>. <I> 1- (S) - </I> </B> Anthrachitiotithioxanthone- 6-carboxylic acid chloride of the formula
EMI0001.0015
with <B> 1 </B> Mol. <B> 1. </B> 5-Diaminoanthrachiiion condensed by heating in a solvent.
<I> Example: </I> <B> 1.6 </B> Part 2 <B>. </B> 1- (S) -Ar) thriichltioi) thioxaiithon-6-kai-hydrochloric acid chloride of the above given formula, available for example from 1-chloranthraebiiion-6-karborisäLire by condensation with thiosalylic acid, ring cooling with sulfuric acid and treating the carboxylic acid obtained with phosphorus pentachloride, in 20 parts of trichlorobenzene with 0.4 part of 1. </B> 5-diaminoanthraquinone heated to about <B> 210-215 0 C </B>,
until dye formation has ended. The dye which separates on cooling is expediently purified by treatment with sodium hypochlorite. He dyes cotton from a violet vat red-brown.
