Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 304388. Verfahren zur Herstellung eines kupferhaltigen Disazofarbstoffes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines kupfer haltigen Disazofarbstoffes, welches darin be steht, dass man 0,6 Mol der durch Kuppeln von dianotierter 2-Amino-l-oxy-6-chlorbenzol- 4-sulfonsäure mit 2-Amino-5-oxynaphthalin-7- sulfonsäure erhaltenen Aminomonoazoverbin- dung und 1,
4 Mol der .durch Kuppeln von dianotierter 2-Amino-1-carboxybenzol-5-sul- fonsäure mit 1-(4'-Amino)-phenyl-3-methyl-5- pyrazolon erhaltenen Aminomonoazoverbin- dung mit 1 Mol eines Pumarsäuredihalogeni- des umsetzt und den erhaltenen Disazofarb- stoff mit kupferabgebenden Mitteln behandelt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile.
<I>Beispiel:</I> 28,4 Teile (= 0,06 Mol) .des durch Kup peln von dianotierter 2-Amino-l-oxy-6-chlor- benzol-4-sulfonsäure mit 2-Amino-5-oxynaph- thalin-7-sulfonsäure erhaltenen Aminomono- azoverbindung und 58,3 Teile (= 0,14 Mol) des durch Kuppeln von dianotierter 2-Amino- 1- carboxybenzol - 5 - sulfonsäure mit 1- (4'- Amino)
-phenyl-3-methyl-5-pyrazolon erhalte nen Aminomonoazoverbindung werden in 4000 Teilen Wasser unter Zusatz von Natrium- earbonat gelöst und bei einer Temperatur von 5 -10 innerhalb von etwa 2 Stunden mit einem Gemisch aus 18 Teilen Fumarsäuredi- chlorid und 30 Teilen Chlorbenzol versetzt. Die Reaktionslösung wird durch Zugabe von Lithiumcarbonat neutral bis schwach alkalisch gehalten. Der entstandene Disazofarbstoff wird aus der Lösung ausgesalzen und ab filtriert.
Zur Überführung in die Kupferkomplex verbindung löst man den erhaltenen Disazo- farbstoff in einer Lösung von 100 Teilen kristallisiertem Natriumacetat in 3000 Teilen Wasser. Bei einer Temperatur von 80-85 fügt man allmählich so viel 20a/oige Kupfer sulfatlösung zu, bis sich im Auslauf einer ausgesalzenen Probe überschüssige Kupfer ionen nachweisen lassen.. Die entstandene Kupferkomplexverbindung wird mit Hilfe von Natriumehlorid abgeschieden, abfiltriert und getrocknet.
Der neue, kupferhaltige Disazofarbstoff ist ein dunkles Pulver und färbt Baumwolle und Fasern aus regenerierter Zellulose in braunen Tönen von sehr guter Lichtechtheit und guter Waschechtheit. Durch Nachbehan- deln. auf der Faser mit Kupfersalzen in Gegenwart eines Polyalkylenpolyamins wer den die Nassechtheitseigenschaften der Fär bungen noch verbessert.
<B> Additional patent </B> to main patent no. 304388. Process for the production of a copper-containing disazo dye. The subject of the present patent is a process for the preparation of a copper-containing disazo dye, which is be that 0.6 mol of the coupling of dianotated 2-amino-1-oxy-6-chlorobenzene-4-sulfonic acid with 2-amino 5-oxynaphthalene-7-sulfonic acid obtained aminomonoazo compound and 1,
4 mol of the aminomonoazo compound obtained by coupling dianotated 2-amino-1-carboxybenzene-5-sulphonic acid with 1- (4'-amino) -phenyl-3-methyl-5-pyrazolone with 1 mol of a pumaric acid dihalogen and the disazo dye obtained is treated with copper-releasing agents.
In the following example, the parts are parts by weight.
<I> Example: </I> 28.4 parts (= 0.06 mol) .des obtained by coupling dianotated 2-amino-1-oxy-6-chlorobenzene-4-sulfonic acid with 2-amino-5 -oxynaphthalene-7-sulfonic acid and 58.3 parts (= 0.14 mol) of the amino-monoazo compound obtained by coupling dianotated 2-amino-1-carboxybenzene-5-sulfonic acid with 1- (4'-amino)
-phenyl-3-methyl-5-pyrazolone obtained aminomonoazo compound are dissolved in 4000 parts of water with the addition of sodium carbonate and at a temperature of 5 -10 within about 2 hours with a mixture of 18 parts of fumaric acid dichloride and 30 parts Chlorobenzene added. The reaction solution is kept neutral to slightly alkaline by adding lithium carbonate. The resulting disazo dye is salted out of the solution and filtered off.
To convert it into the copper complex compound, the disazo dye obtained is dissolved in a solution of 100 parts of crystallized sodium acetate in 3000 parts of water. At a temperature of 80-85, so much 20% copper sulfate solution is gradually added until excess copper ions can be detected in the outflow of a salted-out sample. The resulting copper complex compound is deposited with the aid of sodium chloride, filtered off and dried.
The new, copper-containing disazo dye is a dark powder and dyes cotton and fibers from regenerated cellulose in brown shades of very good lightfastness and good washfastness. By post-treatment. on the fiber with copper salts in the presence of a polyalkylenepolyamine who improves the wet fastness properties of the dyeings.
