Description
Verfahren zur Herstellung eines Küpenfarbstoffes. Es wurde gefunden, da.ss ein wertvoller Küpenfarbstoff hergestellt werden kann, wenn man 1 Mol 1,5-Diaminoanthrachinon- 2,6-dicarbonsäure oder eines ihrer funktionel len Derivate mit 2 Mol 4-Amino-(N)-methyl- 1,9-anthrapyridon umsetzt.
Der neue Farbstoff ist ein dunkelrotes Pulver, das sich in konz. Schwefelsäure mit gelber Farbe löst und Baumwolle aus oliver Küpe in Bordeauxtönen färbt.
Zur Durchführung der LTmsetzung kann die genannte Dicarbonsäure oder vorzugs weise eines ihrer funktionellen Derivate, bei spielsweise ein Säurehalogenid und insbeson dere das Säurechlorid verwendet werden. Die Reaktion wird zweckmässig in einem indiffe renten Lösungs- bezw. Verteilungsmittel vor genommen, wobei insbesondere solche von höherem Siedepunkt, wie Chlorbenzol, Nitro- benzol oder Dichlorbenzol, in Betracht kom men.
Man kann die Umsetzung beispielsweise bei erhöhter Temperatur in An- oder Ab wesenheit säurebindender Mittel durchführen. <I>Beispiel:</I> Zu der Lösung von 13,3 Teilen 4-Amino- (N)-methyl-1,9-anthrapyridon in 500 Teilen trockenem Nitrobenzol gibt man bei 90-100 9,1 Teile 1,5-Diaminoanthraehinon-2,6-diear- bonsäurechlorid. Hierauf steigert man die Temperatur innert 1/2 Stunde auf 150 .
Zur Beendigung der Farbstoffbildung rührt man noch 2 Stunden bei 150-160 , filtriert dann in der Wärme ab, wäscht mit Nitrobenzol und Alkohol aus und trocknet. Das in diesem Beispiel verwendete Säure chlorid kann wie folgt erhalten werden: 5 Teile 1,5-Diaminoanthrachinon-2,6-di- carbonsäure werden mit 60 Teilen trockenem Nitrobenzol vermahlen.
Zu der feinen Sus pension gibt man nun weitere 540 Teile trok- kenes Nitrobenzol, 1 Teil Pyridin und 17 Teile Thionylchlorid hinzu und erhitzt das Gemisch während 1/.4 Stunde auf 90-100 . Dabei geht die 1,5-Diaminoanthrachinon-2,6- diearbonsäure in Lösung. Man filtriert von einigen Verunreinigungen ab und lässt das Filtrat erkalten. Das 1,5-Diaminoanthrachi- non-2,6-dicarbonsäurechlorid kristallisiert in grünlich schillernden, rotbraunen Nadeln aus.
Es wird abgesaugt, mit Aceton und Wasser (zur Entfernung von salzsaurem Pyridin) ge waschen und im Exsiccator getrocknet.
Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if 1 mol of 1,5-diaminoanthraquinone-2,6-dicarboxylic acid or one of its functional derivatives is mixed with 2 mol of 4-amino (N) -methyl-1, 9-anthrapyridone converts.
The new dye is a dark red powder that is in conc. Sulfuric acid dissolves with a yellow color and dyes cotton from an olive vat in shades of Bordeaux.
The dicarboxylic acid mentioned or preferably one of its functional derivatives, for example an acid halide and in particular the acid chloride, can be used to carry out the reaction. The reaction is expediently in an indifferent solution or. Distribution agents taken before, in particular those with a higher boiling point, such as chlorobenzene, nitrobenzene or dichlorobenzene, are suitable.
The reaction can be carried out, for example, at elevated temperature in the presence or absence of acid-binding agents. <I> Example: </I> 9.1 parts 1.5 are added to the solution of 13.3 parts of 4-amino- (N) -methyl-1,9-anthrapyridone in 500 parts of dry nitrobenzene at 90-100 -Diaminoanthraehinone-2,6-diarboxylic acid chloride. The temperature is then increased to 150 within 1/2 hour.
To complete the formation of the dye, the mixture is stirred for a further 2 hours at 150-160, then filtered off in the heat, washed with nitrobenzene and alcohol and dried. The acid chloride used in this example can be obtained as follows: 5 parts of 1,5-diaminoanthraquinone-2,6-dicarboxylic acid are ground with 60 parts of dry nitrobenzene.
A further 540 parts of dry nitrobenzene, 1 part of pyridine and 17 parts of thionyl chloride are then added to the fine suspension, and the mixture is heated to 90-100 for 1/4 hour. The 1,5-diaminoanthraquinone-2,6-diacid goes into solution. Some impurities are filtered off and the filtrate is allowed to cool. The 1,5-diaminoanthraquinone-2,6-dicarboxylic acid chloride crystallizes out in greenish shimmering, red-brown needles.
It is filtered off with suction, washed with acetone and water (to remove hydrochloric acid pyridine) and dried in a desiccator.
