Description
Verfahren zur Herstellung eines ehromhaltigen Azofarbstoffes. Es wurde gefunden, dass man einen chrom- haltigen Azofarbstoff durch Einwirkung des chromhaltigen Farbstoffes, der durch Ohro- mieren des Azofarbstoffes aus dianotierter 1-Amino-2-oxynaphthalin-4-sulfonsäure und 1-Oxynaphthalin-8-sulfonsäure entsteht,
auf den Azofarbstoff aus dianotierter 1-Amino- 2 - oxynaphthalin - 4-sulfonsäure und 1- Oxy- naphthalin erhalten kann, wenn diese Ein wirkung in alkalischem Medium erfolgt.
Der erhaltene neue chromhaltige Azofarb- stoff ist in Wasser mit blauer .Farbe löslich und färbt Wolle aus saurem Bade in blauen Tönen von hervorragenden Echtheiten. <I>Beispiel:</I> 70 Teile der Chromverbindung des Azo- farbstoffes aus dianotierter 1-Amino.2-oxy- naphthaliri-4-sulfonsäure und 1-Oxynaphtha- lin-8-sulfonsäure werden mit 21 Teilen des Azofarbstoffes aus dianotierter 1-Amino-2-oxy- naphthalin-4-sulfonsäure und <RTI
ID="0001.0030"> 1-Oxynaphthalin in 800 Teilen Wasser und 100 Teilen 30o/oiger Natronlauge unter Zusatz von 5 Teilen Zucker gelöst und 4 Stunden rückfliessend gekocht. Nach Zugabe von 10o/oiger Salzsäure und wenig Ameisensäure bis zur schwach lack mussauren Reaktion wird im Vakuum zur Trockne verdampft.
Zu demselben chromhaltigen Azofarbstoff gelangt man, wenn statt Natronlauge andere Alkalien wie z. B. Kalilauge, Soda, Pottasche, Borax, Magnesiumoxyd, Calciumhydroxyd, Ammoniak oder Trialkaliphosphat verwendet werden.
Process for the preparation of an azo dye containing Ehrom. It has been found that a chromium-containing azo dye is produced by the action of the chromium-containing dye which is formed by earromizing the azo dye from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and 1-oxynaphthalene-8-sulfonic acid,
on the azo dye from dianotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 1-oxynaphthalene can be obtained if this action takes place in an alkaline medium.
The new chromium-containing azo dye obtained is soluble in water with a blue color and dyes wool from an acid bath in blue shades of excellent fastness properties. <I> Example: </I> 70 parts of the chromium compound of the azo dye from dianotated 1-amino.2-oxynaphthalen-4-sulfonic acid and 1-oxynaphthalin-8-sulfonic acid are dianotated with 21 parts of the azo dye 1-amino-2-oxynaphthalene-4-sulfonic acid and <RTI
ID = "0001.0030"> 1-oxynaphthalene dissolved in 800 parts of water and 100 parts of 30% sodium hydroxide solution with the addition of 5 parts of sugar and refluxed for 4 hours. After 10% hydrochloric acid and a little formic acid have been added until the reaction is slightly acidic, the mixture is evaporated to dryness in vacuo.
The same chromium-containing azo dye is obtained if, instead of sodium hydroxide, other alkalis such as. B. potassium hydroxide, soda, potash, borax, magnesium oxide, calcium hydroxide, ammonia or trialkali phosphate can be used.
