Description

Verfahren zur Darstellung von Küpenfarbstoffen der Anthrachinonreihe Nach dem Verfahren der Patente 465 835 und 514 518 werden Dianthrachinonylaininderivate, welche neben einem Acridonring noch mindestens eine Acylaminogruppe enthalten, durch Einwirkung von Schwefelsäure in Carbazolderivate übergeführt.Process for the preparation of vat dyes of the anthraquinone series According to the process of patents 465 835 and 514 518 , dianthraquinonylainin derivatives, which in addition to an acridone ring also contain at least one acylamino group, are converted into carbazole derivatives by the action of sulfuric acid.

Es wurde nun gefunden, daß sich auch solche Diantbrachinonylaminderivate, welche keine Acylaminogruppe, dagegen aber mindestens zwei Acridonringe enthalten, durch Einwirkung von Schwefelsäure bei niederer Temperatur und gegebenenfalls nachfolgende Oxydation des erhaltenen Zwischenproduktes carbazolieren lassen. Die neuen so erhaltenen Carbazolderivate sind wertvolle Küpenfarbstoffe oder sollen als Zwischenprodukte für solche Verwendung finden.It has now been found that such Diantbrachinonylaminderivate, which do not contain an acylamino group, but contain at least two acridone rings, by exposure to sulfuric acid at low temperature and, if necessary, subsequent Let oxidation of the intermediate product obtained carbazole. The new so obtained Carbazole derivatives are valuable vat dyes or should be used as intermediates find for such use.

B e i s p i e 1 ?,i Gewichtsteile Trichloranthrachinonacridon (erhalten durch Chlorieren von Anthrachinoii-N.i.2.acridon in Nitrobenzol) und 2o Gewichtsteile 4-Aminodichloracridon (erhalten nach dem Verfahren des Patents 5 15 3:29, Beispiel 2, durch Umsetzung- des obengenannten Trichloranthrachinollaeridons init p-Toluolsulfamid und nachherige Vere seifung) werden, wie im Patent 51jo-[5 beschrieben, mit io Gewichtsteilen Natriumacetat und i Gewichtsteil Kupferchlorür in 5ooGewichtsteilen Naphthalin einige Stunden zum Sieden erhitzt. Das sich in wohlausgebildeten dunklen Kriställchen abscheidende Kondensationsprodukt wird in der üblichen Weise aufgearbeitet.B eis p ie 1 ?, I parts by weight of trichloroanthraquinone acridone (obtained by chlorinating anthraquinone-Ni2.acridone in nitrobenzene) and 2o parts by weight of 4-aminodichloroacridone (obtained by the method of patent 5 1 5 3:29, Example 2, by reaction of the The above-mentioned trichloroanthraquinol aeridons with p-toluenesulfamide and subsequent soaping) are heated to boiling for a few hours with 10 parts by weight of sodium acetate and 1 part by weight of copper chloride in 500 parts by weight of naphthalene, as described in the 51jo- [5 patent. The condensation product, which separates out in well-formed dark crystals, is worked up in the usual way.

5 Gewichtsteile des so erhaltenen Dianthrachinonacridonylamins werden bei etwa 2o' in 5o Gewichtsteilen konzentrierter Schwefelsäure gelöst. Die anfangs gelbbraune Lösungsfarbe geht schon nach kurzer Zeit in Oliv über. Wenn sich die Lösungsfarbe nicht mehr ändert gießt man die Schmelze in 5oo Gewichtsteile Wasser, dem man 3 Gewichtsteile Natriumnitrit zugesetzt hat, und erwärmt 1"#, Stunde auf 7o'. Man erhält so den neuen Farbstoff in grünen Flokken, die filtriert und gewaschen werden. Anstatt das Natritimnitrit, in Wasser gelöst, zur Einwirkung zu bringen, kann man die berechnete Menge Natriunmitrit auch der schwefelsauren Lösung zusetzen, wobei die ursprünglich olive Lösungsfarbe in ein klares Grünblau übergeht. Der Farbstoff färbt aus gelboliver Küpe Baumwolle in echten grünen Tönen an. 5 parts by weight of the dianthraquinonacridonylamine thus obtained are dissolved in 50 parts by weight of concentrated sulfuric acid at about 20 '. The initially yellow-brown solution color changes to olive after a short time. When the color of the solution no longer changes, the melt is poured into 500 parts by weight of water to which 3 parts by weight of sodium nitrite has been added and heated to 70 'for 1 "# hour. This gives the new dye in green flakes, which are filtered and washed Instead of bringing the sodium nitride, dissolved in water, into action, the calculated amount of sodium nitride can also be added to the sulfuric acid solution, whereby the originally olive solution color changes into a clear green-blue. The dye stains cotton in real green tones from a yellow-olive vat.

Die Oxydation kann auch init anderen gebräuchlichen Oxydationsmitteln, wie z. B. Chromsäure, ausgeführt werden.The oxidation can also be carried out with other common oxidizing agents, such as B. chromic acid.
