Description
Verfahren zur Herstellung von Küpenfarbstoffen Es wurde gefunden, dass wertvolle Küpen Farbstoffe erhalten werden, wenn. ein 2-Amino- 3.4-phthalyl-acridon mit einem 1-(3'-Halogen- benzoylämino) -anthrachinon kondensiert wird.
Das 2-Amino-3.4-phthalyl-aeridon kann in 5-, 6-, 7- oder 8-Stellung noch ein Halogenatom und das 1-(3'-Halogen-benzoylamino)-anthra- chinon in 5-Stellung noch eine Aroylamino- gruppe -oder in 4.10- oder 5.10-Stellung noch einen. ankondensierten Pyrimidinring enthal ten.
Diese Küpenfarbstoffe färben und drucken Zellulosematerial in klaren, gelbstichig grünen Tönen von sehr guten Echtheitseigenschaften. <I>Beispiel</I> Ein Gemisch aus 400 Teilen Nitrobenzol, 15 Teilen 1-(3'-Brombenzoylamino)-anthra- chinon,10 Teilen. 2-Amino-3.4-phthalyl-acridon, 5 Teilen Natriumacetat, 0,5 Teilen Küpfer- aeetat und 0,5 Teilen Küpferpulver wird 1.2 Stunden auf 200 erhitzt.
Dann wird mässig warm abgesaugt und der Rückstand zunächst mit Nitrobenzol, dann mit Methanol und schliesslich mit heissem Wasser gut ausge waschen. Das getrocknete, grüne Farbstoff pulver löst sieh in Schwefelsäure mit brauner Farbe und färbt und druckt die pflanzliche Faser in klaren, gelbstichig grünen Tönen.
Wird in dem obigen Beispiel das 2-Amino- 3.4-phthalyl-aeridon ersetzt durch 2-Amino-6- chlor - 3.4 - phthalyl- acridon oder durch 2 Amino-7-chlor-3.4,phthalyl-acridon, so werden Farbstoffe erhalten, die in etwas gelbstichiger grünen Tönen färben und drucken.
Die An wendung von 1-(3'-Brom-benzoylamino)-5- benzoylamino-anthrachinon oder von 4-(3' Brom-benzoylamino)-anthrapyrimidin (1.9) an Stelle des 1-(3'-Brom benzoylamino)-an- thrachinons führt bei der obigen Kondensa tion zu Farbstoffen, die die pflanzliche Faser in wesentlich gelbstichiger grünen, Tönen färben und drucken als der Farbstoff, der ge mäss' Absatz 1 dieses Beispiels erhalten wird.
Process for the preparation of vat dyes It has been found that valuable vat dyes are obtained when. a 2-amino-3,4-phthalyl-acridone is condensed with a 1- (3'-halobenzoylamino) -anthraquinone.
The 2-amino-3,4-phthalyl-aeridone can also have a halogen atom in the 5-, 6-, 7- or 8-position and the 1- (3'-halo-benzoylamino) -anthraquinone can also have an aroylamino in the 5-position - group - or in the 4.10 or 5.10 position another one. fused-on pyrimidine ring.
These vat dyes dye and print cellulose material in clear, yellowish green tones with very good fastness properties. <I> Example </I> A mixture of 400 parts of nitrobenzene, 15 parts of 1- (3'-bromobenzoylamino) anthraquinone, 10 parts. 2-Amino-3,4-phthalyl-acridone, 5 parts of sodium acetate, 0.5 part of Küpfer- aeetat and 0.5 part of Küpferpulver is heated to 200 for 1.2 hours.
Then it is filtered off with suction at a moderate temperature and the residue is washed out thoroughly, first with nitrobenzene, then with methanol and finally with hot water. The dried, green dye powder dissolves in sulfuric acid with a brown color and dyes and prints the vegetable fibers in clear, yellowish green tones.
If in the above example the 2-amino-3,4-phthalyl-aeridone is replaced by 2-amino-6-chloro-3.4-phthalyl-acridone or by 2-amino-7-chloro-3.4-phthalyl-acridone, dyes are obtained, which dye and print in slightly yellowish green tones.
The use of 1- (3'-bromo-benzoylamino) -5-benzoylamino-anthraquinone or 4- (3 'bromo-benzoylamino) -anthrapyrimidine (1.9) instead of 1- (3'-bromo benzoylamino) -an - Thrachinons leads in the above condensation to dyes that dye and print the vegetable fiber in significantly more yellowish green tones than the dye obtained according to paragraph 1 of this example.
