Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 304388. Verfahren zur Herstellung eines metallisierbaren Disazofarbstoffes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines metalli- sierbaren Disazofarbstoffes, welches darin be steht, da.ss man 1 Mol der durch saures Kup peln von diazotierter 1-(4'-Amino)
-benzoyl- amino 2-oxy-3-carboxybenzol-5-sulfonsäure mit 7 -Amino-3-methylbenzol hergestellten Amino- monoazoverbindung und 1 Mol der durch Kuppeln von diazotierter 2-Amino-l-carboxy- benzol-5-sulfonsäure mit 1-(4'-Amino)
-phenyl- 3 - methyl - 5 - pyrazolon erhältlichen Amino- monoazoverbindung mit 1 Mol eines Fumar- säuredihalogenides umsetzt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile, und die Prozente sind in (Tewichtsprozenten angegeben.
<I>Beispiel:</I> 47 Teile (=0,1 Mol) der durch saures Kuppeln von diazotierter 1-(4'-Amino)-ben- zoylamino-2-oxy-3-ca.rboxybenzol-5-sulfonsäure mit 1- Amino - 3 -methylbenzol erhältlichen Aminomonoazoverbindung und 41,7 Teile (-0,1 Mol) der durch Kuppeln von diazo- tierter 2-Amino-l-carboxybenzol-5-sulfonsäure mit 1-(4'-Amino)
-phenyl-3-methyl-5-pyrazolon hergestellten Aminomonoazoverbindung wer den mit einem Überschuss an Natriumbicar- bonat in 3000 Teilen Wasser gelöst. Die Lö sung wird, nachdem sie durch Zugabe von Eis auf ungefähr 5 gekühlt worden ist, innerhalb von 3 Stunden gleichmässig mit. so viel einer 2011/oigen Fumarsäuredibromidlösung in Chlor benzol versetzt, bis darin keine freie Amino- gruppe mehr nachgewiesen werden kann.
Durch Zutropfen einer Natriumbicarbonat- lösung wird die Reaktion der Kondensations masse stets alkalisch gehalten. Hierauf wird der gebildete Disazofarbstoff nach den übli chen Methoden durch Aussalzen mit Na triumchlorid abgeschieden, abfiltriert und ge trocknet.
Der neue, metallisierbare Disazofarbstoff stellt ein gelbbraunes Pulver dar, welches sich in konzentrierter Schwefelsäure mit orangeroter, in Wasser mit gelber Farbe löst und Baumwolle und Fasern aus regenerierter Zellulose in reinen gelben Tönen färbt. Die Färbungen des neuen Disazofarbstoffes sind, besonders wenn sie mit kupferabgebenden Mitteln behandelt werden, licht- und nassecht.
<B> Additional patent </B> to main patent no. 304388. Process for the production of a metallizable disazo dye. The subject of the present patent is a process for the preparation of a metallizable disazo dye, which is that 1 mol of 1- (4'-amino) diazotized by acid coupling of
-benzoyl-amino 2-oxy-3-carboxybenzene-5-sulfonic acid with 7-amino-3-methylbenzene amino monoazo compound and 1 mol of the by coupling of diazotized 2-amino-1-carboxy-benzene-5-sulfonic acid with 1 - (4'-amino)
-phenyl- 3 - methyl - 5 - pyrazolone available amino monoazo compound with 1 mol of a fumaric acid dihalide.
In the following example, the parts are parts by weight and the percentages are given in (percent by weight.
<I> Example: </I> 47 parts (= 0.1 mol) of 1- (4'-amino) -benzoylamino-2-oxy-3-approx .rboxybenzene-5-sulfonic acid which has been diazotized by acidic coupling with 1- amino - 3-methylbenzene aminomonoazo compound obtainable and 41.7 parts (-0.1 mol) of the by coupling diazotized 2-amino-1-carboxybenzene-5-sulfonic acid with 1- (4'-amino)
-phenyl-3-methyl-5-pyrazolone aminomonoazo compound prepared who dissolved the with an excess of sodium bicarbonate in 3000 parts of water. The solution becomes evenly with within 3 hours after it has been cooled to about 5 by adding ice. enough of a 2011 / o fumaric acid dibromide solution in chlorobenzene was added until no free amino group can be detected in it.
The reaction of the condensation mass is always kept alkaline by adding a sodium bicarbonate solution dropwise. The disazo dye formed is then deposited by the usual methods by salting out with sodium chloride, filtered off and dried.
The new, metallizable disazo dye is a yellow-brown powder, which dissolves in concentrated sulfuric acid with orange-red, in water with yellow color and dyes cotton and fibers made of regenerated cellulose in pure yellow tones. The colorations of the new disazo dye, especially when treated with copper-releasing agents, are lightfast and wetfast.
