<B>Zusatzpatent</B> zum hauptpatent Nr. 293432. Verfahren zur Herstellung eines Disazofarbstoffes. Es wurde gefunden, dass man zu einem wertvollen Disazofarbstoff gelangt, we das Dipyrazolon der Formel
EMI0001.0009
beidseitig mit diazotierter 2-Amino-l-oxyben- zol-4-carbonsäurephenylamidsulfonsäure kup pelt,
in welcher die Sulfonsäuregruppe die selbe Stellung einnimmt wie diejenige der durch Sulfonierung von 2-Nitro-1.-oxybenzol- 4-carbonsäurephenylamid erhältlichen 2-Ni- tro-l-oxybenzol - 4- carbonsäurephenylamidsul- fonsäure, und den erhaltenen Farbstoff mit kupferabgebenden Mitteln behandelt.
Der neue Farbstoff stellt ein rotbraunes Pulver dar, das sich in Wasser, verdünnter Natriumcarbonatlösung und verdünnter Na triumhydroxydlösung mit rotbrauner und in konzentrierter Schwefelsäure mit gelber Farbe löst. Er färbt Baumwolle und Fasern aus re generierter Cellulose in gelbbraunen Tönen von guter Waschechtheit und ganz vorzügli cher Lichtechtheit.
Die Diazokomponente des vorliegenden Verfahrens wird zweckmässig durch Sulfonie- ren von 2-Nitro-l-oxybenzol-4-carbonsäurephe- nylamid und nachfolgender Reduktion der 2- Nitro-1- oxybenzol - 4 - carbonsäurephenylaznid- sulfonsäure erhalten, Die Diazotierung der 2-Amino-l-oxyben- zol-4-carbonsäurephenylamidsulfonsäure kann nach an sich bekannten Methoden erfolgen,
mit Vorteil nach der sogenannten indirekten Methode, das heisst dadurch, dass man eine Lösung, die ein Alkalisalz der als Diazokom- ponente dienenden Sulfonsäure sowie die er forderliche Menge Nitrit enthält, mit einer einen LTberschuss über die theoretisch benö tigte Menge Säure, insbesondere Salzsäure, enthaltenden, verdünnten Säurelösung verei nigt.
Die Kupplung wird beim vorliegenden Verfahren mit Vorteil in alkalischem Medümz durchgeführt. Die Umwandlung des Farb stoffes in die komplexe Kupferverbindung er folgt zweckmässig nach an sich bekannten Me thoden.
<I>Beispiel:</I> In 100 Teile rauchende Schwefelsäure mit einem Anhydridgehalt von 24% trägt man portionenweise unter gutem Rühren 51,6 Teile 2 -Nitro -1-oxybenzol-4-carbonsäurephenylamid ein. Durch Aussenkühlung sorgt man dafür, dass die Temperatur nicht über 25 steigt. Nach beendigtem Eintragen rührt man noch 30 Minuten weiter und giesst dann auf Eis.
Hierauf gibt man so viel Natriumhydroxyd- lösung zu, dass das Reaktionsgemiseh nur noch schwach sauer reagiert, und filtriert. das sulfo nierte Produkt ab. Bei der Reduktion nach Bechamp-Brimmeyr mit Eisen und wenig Es sigsäure wird daraus ein helles Produkt er halten, das sieh aus 70a/eigem Alkohol umkri- stallisieren lässt.
61,6 Teile des sulfonierten Produktes wer den indirekt diazotiert, indem man diese Menge zusammen mit 11 Teilen Natriumcarbo- nat in 1500 Teilen Wasser löst, mit 13,8 Tei len Natriumnitrit versetzt und bei 0 bis 5 zu 80 Teilen 30a/aiger Salzsäure und 400 Teilen 'NVasser fliessen lässt. Nach etwa 3 Stunden ist die Diazotiering beendet.
Diese Diazosuspension lässt man bei 0 bis 5 zu einer Lösung von 53,2 Teilen des Di- pyrazolons aus 4,4'-Diaminostilben-2,2'-disul- fonsäure und 80 Teilen Natriumcarbonat flie ssen. Nach dem Rühren über Nacht scheidet man den Farbstoff durch Zusatz von Na triumchlorid ab-, filtriert und wäscht mit Na- triumchloridlösung nach.
Zur Kupferung löst man den Disazofarbstoff in 5000 Teilen Was ser uird setzt bei 70 bis 80 eine Kupfertetram- minsulfatlösung zu, bestehend aus 50 Teilen kristallisiertem Kupfersulfat in 200 Teilen 1@Tasser und<B>100</B> Teilen 20a/aigem Ammoniak. Man hält eine Stunde bei 7 0 bis 80 , seheidet die komplexe Kupferverbindung durch Zusatz von Natriumchlorid ab und trocknet sie.
<B> Additional patent </B> to main patent no. 293432. Process for the production of a disazo dye. It has been found that one arrives at a valuable disazo dye, such as the dipyrazolone of the formula
EMI0001.0009
on both sides with diazotized 2-amino-1-oxybenzene-4-carboxylic acid phenylamide sulfonic acid,
in which the sulfonic acid group occupies the same position as that of the 2-nitro-1-oxybenzene-4-carboxylic acid phenylamide sulfonic acid obtainable by sulfonation of 2-nitro-1-oxybenzene-4-carboxylic acid phenylamide, and the dye obtained with copper-releasing agents treated.
The new dye is a red-brown powder that dissolves in water, dilute sodium carbonate solution and dilute sodium hydroxide solution with red-brown and concentrated sulfuric acid with a yellow color. It dyes cotton and fibers made from regenerated cellulose in yellow-brown shades with good washfastness and excellent lightfastness.
The diazo component of the present process is expediently obtained by sulfonating 2-nitro-1-oxybenzene-4-carboxylic acid phenylamide and subsequent reduction of the 2-nitro-1-oxybenzene-4-carboxylic acid phenylaznide sulfonic acid. The diazotization of the 2-amino -l-oxybenzene-4-carboxylic acid phenylamide sulfonic acid can be carried out according to methods known per se,
with advantage according to the so-called indirect method, that is, a solution containing an alkali salt of the sulfonic acid serving as the diazo component and the required amount of nitrite, with an excess of the theoretically required amount of acid, in particular hydrochloric acid, containing, dilute acid solution combined.
In the present process, the coupling is advantageously carried out in an alkaline medium. The conversion of the dye into the complex copper compound he expediently follows methods known per se.
<I> Example: </I> 51.6 parts of 2-nitro-1-oxybenzene-4-carboxylic acid phenylamide are introduced in portions into 100 parts of fuming sulfuric acid with an anhydride content of 24% with thorough stirring. External cooling ensures that the temperature does not rise above 25. When the addition is complete, stirring is continued for 30 minutes and then poured onto ice.
Sufficient sodium hydroxide solution is then added so that the reaction mixture only reacts slightly acidic, and it is filtered. the sulfonated product. In the Bechamp-Brimmeyr reduction with iron and a little acetic acid, a light-colored product is obtained that can be recrystallized from 70% own alcohol.
61.6 parts of the sulfonated product are indirectly diazotized by dissolving this amount together with 11 parts of sodium carbonate in 1500 parts of water, adding 13.8 parts of sodium nitrite and, at 0 to 5, to 80 parts of 30% hydrochloric acid and 400 parts' N lets water flow. The diazotization is complete after about 3 hours.
This diazo suspension is allowed to flow at 0 to 5 to a solution of 53.2 parts of the dipyrazolone of 4,4'-diaminostilbene-2,2'-disulfonic acid and 80 parts of sodium carbonate. After stirring overnight, the dye is separated off by adding sodium chloride, filtered and washed with sodium chloride solution.
For copper plating, the disazo dye is dissolved in 5000 parts of water and a copper tetramine sulfate solution is added at 70 to 80 parts, consisting of 50 parts of crystallized copper sulfate in 200 parts of 1 cup and 100 parts of 20% ammonia. It is held at 70 to 80 for an hour, the complex copper compound is separated off by adding sodium chloride and dried.
