Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 166497. Verfahren zur Herstellung eines chromhaltigen Azofarbstoffes. Es wurde gefunden, dass man einen chrom- haltigen Azofarbstoff durch Einwirkung des chromhaltigen Azofarbstoffes, der durch Chro- mieren des Azofarbstoffes aus dianotierter 1-Amino-2-oxynaphthalin-4-sulfonsäure und 2-Oxynaphthalin entsteht,
auf den Azofarb- stoff aus dianotierter 1-Amino-2-oxynaphthalin- 4-sulfonsäure und 1-Oxynaphthalin erhalten kann, wenn diese Einwirkung in alkalischem Medium erfolgt.
Der erhaltene chromhaltige Azofarbstoff ist in Wasser leicht löslich und färbt Wolle aus organischsaurem-schwefelsaureni Bade in marineblauen Tönen von vorzüglichen Echt- heiten.
<I>Beispiel:</I> 110 Teile der Chromverbindung des Azo- farbstoffes aus dianotierter 1-Amino-2-oxy- naphthalin-4-sulfonsäure und 2-Oxynaphthalin werden in einem Gemisch 1500 Teilen Wasser, 200 Teilen 30o/oiger Natronlauge und 10 Tei len Zucker gelöst, hierauf 41,6 Teile des Azofarbstoffes aus dianotierter 1-Amino-2-oxy- naphthalin-4-sulfonsäure und 1-Oxynaphtha- lin zugefügt, und die Mischung wird 4 Stun den rückfliessend gekocht.
Nach dem Abküh len auf<B>60'</B> wird mit 10o/oiger Salzsäure und etwas Ameisensäure schwach lackmussauer gestellt und die blaue Lösung 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.
<B> Additional patent </B> to main patent no. 166497. Process for the production of a chromium-containing azo dye. It has been found that a chromium-containing azo dye is produced by the action of the chromium-containing azo dye, which is formed by chroming the azo dye from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and 2-oxynaphthalene,
on the azo dye from dianotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 1-oxynaphthalene, if this action takes place in an alkaline medium.
The chromium-containing azo dye obtained is easily soluble in water and dyes wool from an organic-sulfuric acid bath in navy blue shades of excellent fastness.
<I> Example: </I> 110 parts of the chromium compound of the azo dye from dianotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 2-oxynaphthalene are mixed in a mixture of 1500 parts of water and 200 parts of 30% sodium hydroxide solution and 10 parts of sugar, then 41.6 parts of the azo dye from dianotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 1-oxynaphthalene are added, and the mixture is refluxed for 4 hours.
After cooling down to <B> 60 '</B>, 10% hydrochloric acid and a little formic acid are used to make a weak lacquer wall and the blue solution is evaporated to dryness in a vacuum.
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.
