Description
Verfahren zur Herstellung eines kupferhaltigen Trisazofarbstoffes. Es wurde gefunden, dass man sehr wert volle, kupferhaltige Trisazofarbstoffe erhält, wenn man Tetrazodiphenyl und seine Sub- stitutionsprodukte halbseitig mit einer o- Oxyaryl-carbonsäure kuppelt, die erhaltene Diazoazoverbindung mit einem in p-Stellung kuppelnden aromatischen Amin bezw. einer Aminosulfonsäure,
die in o-Stellung zur di- azotierbaren Aminogruppe einen zur Bildung von Metallkomplexverbindungen befähigten Substituenten enthalten, vereinigt, den Aminodisazofarbstoff weiter diazotiert, mit einem N-Substitutionsprodukt der 2-Amino- 6-oxynaphthalin-8-sulfonsäure kuppelt und den Trisazofarbstoff nach üblichen Verfah ren in die gupferkomplexverbindungen über führt.
Die neuen gekupferten Farbstoffe be sitzen substantive Eigenschaften und färben in grünen bis oliven Tönen, die ausgezeich net sind durch eine hervorragende Lichtecht heit. Gegebenenfalls können die neuen Farbstoff-Kupferverbindungen auch auf der Faser noch weiter gekupfert werden.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung .eines kupfer haltigen Trisazofarbstoffes, dadurch gekenn zeichnet, dass man 1 Mol. tetrazotiertes Benz- idin alkalisch mit 1 Mol. o-gresotinsäure und anschliessend die Diazoazoverbindung sauer mit 1 Mol. 1-Amino-2-äthoxynaphthalin-6- sulfonsäure kuppelt,
den erhaltenen Amino- -disazofarbstoff weit.erdiazotiert, mit 1 Mol. 2- Acetylamino- 6-oxynaphthalin- 8 -sulfonsäure vereinigt und den Trisazofarbstoff mit kup ferabgebenden Verbindungen behandelt.
<I>Beispiel:</I> 18,4 Teile Benzidin werden wie üblich in salzsaurer Lösung mit 14 Teilen Natrium- nitrit tetrazotiert und zuerst sodaalkalisch mit 16,0 Teilen o-gresotinsäure und hierauf die Diazoazoverbindung essigsauer mit 26,7 Teilen 1-Amino-2-naphtoläthyläther-6-sul- fonsäure gekuppelt.
Der erhaltene Disazo- farbstoff wird mit 20 Teilen Soda alkalisch gestellt, isoliert, in 2000 Teilen Wasser ge löst, mit 7,2 Teilen Natriumnitrit versetzt und durch Zustürzen von 70 Teilen konzen- trierter Salzsäure bei 10 diazotiert. Den abgeschiedenen Diazokörper trägt man in eine Lösung von 28,1 Teilen 2-Acetylamino- 6-ogynaphthalin-8-sulfonsäure,
40 Teilen 25%igem Ammoniak und 150 Teilen Pyri- din in 200 Teilen Wasser ein. Der fertig gebildete Farbstoff wird mit 5 ,"/o Kochsalz ausgesalzen, filtriert und mit 2,5 % iger Sole gewaschen.
Zur Kupferung in Substanz löst man den erhaltenen Trisazofarbstoff in 1600 Teilen Wasser von 95 . gibt eine Lösung von 25 Teilen kristallisiertem Kupfersulfat zu und kocht während 4 Stunden. Der Farbstoff wird abfidtriert und in das Natriumsalz übergeführt. Er stellt ein schwarzes Pulver dar, das sich in Wasser mit olivegrüner, in Schwefelsäure mit stumpf violetter Farbe löst.
Er färbt Baumwolle aus dem neutralen Glaubersalzbad in olivegrünen Tönen von hervorragender Lichtechtheit.
Ebensogut kann der Farbstoff im neu tralen Glaubersalzbad auf Baumwolle ge- färbt und wie üblich mit Kupfersulfat nacht behandelt werden.
Process for the production of a copper-containing trisazo dye. It has been found that very valuable, copper-containing trisazo dyes are obtained if tetrazodiphenyl and its substitution products are coupled on one side with an o-oxyaryl-carboxylic acid, the diazoazo compound obtained with an aromatic amine coupling in the p-position, respectively. an aminosulfonic acid,
which contain a substituent capable of forming metal complex compounds in the o-position to the diacotable amino group, combined, further diazotized the amino disazo dye, coupled with an N-substitution product of 2-amino-6-oxynaphthalene-8-sulfonic acid and the trisazo dye by conventional methods Ren leads into the copper complex compounds.
The new copper-plated dyes have substantive properties and color in green to olive tones, which are characterized by excellent lightfastness. If necessary, the new dye-copper compounds can also be further copper-plated on the fiber.
The subject matter of the present patent is a process for the production of a copper-containing trisazo dye, characterized in that 1 mol of tetrazotized benzidine is alkaline with 1 mol of o-gresotinic acid and then the diazoazo compound is acidic with 1 mol of 1-amino-2 -ethoxynaphthalene-6-sulfonic acid couples,
the resulting amino disazo dye weit.erdiazotiert, combined with 1 mol. 2-acetylamino-6-oxynaphthalene-8-sulfonic acid and treated the trisazo dye with copper-releasing compounds.
<I> Example: </I> 18.4 parts of benzidine are tetrazotized as usual in hydrochloric acid solution with 14 parts of sodium nitrite and first alkaline with 16.0 parts of o-gresotinic acid and then the diazoazo compound with 26.7 parts of acetic acid Amino-2-naphtholethyl ether-6-sulphonic acid coupled.
The disazo dye obtained is made alkaline with 20 parts of soda, isolated, dissolved in 2000 parts of water, treated with 7.2 parts of sodium nitrite and diazotized at 10 by adding 70 parts of concentrated hydrochloric acid. The deposited diazo body is carried in a solution of 28.1 parts of 2-acetylamino-6-ogynaphthalene-8-sulfonic acid,
40 parts of 25% ammonia and 150 parts of pyridine in 200 parts of water. The finished dye is salted out with 5% sodium chloride, filtered and washed with 2.5% strength brine.
For coppering in bulk, the trisazo dye obtained is dissolved in 1,600 parts of 95 water. add a solution of 25 parts of crystallized copper sulfate and boil for 4 hours. The dye is filtered off and converted into the sodium salt. It is a black powder that dissolves in water with an olive green color and in sulfuric acid with a dull purple color.
It dyes cotton from the neutral Glauber's salt bath in olive-green shades of excellent lightfastness.
The dye can just as well be dyed on cotton in the neutral Glauber's salt bath and treated overnight with copper sulfate as usual.
