Description
Verfahren zur Darstellung eines Polyazofarbstoffes. Es wurde gefunden, dass man zu einem wertvollen grünen Direktfarbstoff gelangt, wenn man die dianotierte Aminoazoverbin- dung aus dianotierter 4-Amirroacetariilid-3- sulfosäure und 1-Amir)o-2-oxyriaphtalin-ox- iith3-läther@schwefelsäureester mit dem Konden sationsprodukt aus molaren Mengen Cyanur- phlorid,
1-Äthylamino-8-oxynaphtalin-3.6- disulfosärrre, 4-Arnino-4'-oxyazobenzol-2.3'- dicarbonsäure und 4-Methyl-l-thiopherrol kup pelt.
<I>Beispiel</I> Die in bekannter Weise hergestellte Diazo- verbindung aus 524 Gewichtsteilen des Azo- farbstoffes aus 4-Aminoacetanilid-3-sulfosäure und 1-Amino - 2 - oxynaphtalin - oxäthylschwe- felsäureester von der Formel:
EMI0001.0027
wird mit Eiswasser verpastet und zu der zweckmässig mit Pyridin versetzten Lösung des Kondensationsproduktes aus molaren Men gen Cyanurchlorid, 1-Äthylamino-8-oxynaph- talicr-3.6-disulfosiiure, 4-Amirro-4'-oxyazoben- zol-2. 3'-dicarbonsäure und 4-Methyl-l-thiophe- nol bei 5-10 gegeben.
Der wie üblich aufgearbeitete Farbstoff stellt in trockenem Zustand ein dunkles bronze glänzendes Pulver dar, das sich mit grüner Farbe in Wasser löst und aus-dem Glaubersalz Sodabad in leuchtend grünen Tönen von sehr guter Lichtechtheit auf die pflanzliche Faser zieht.
Process for the preparation of a polyazo dye. It has been found that a valuable green direct dye is obtained if the dianotated aminoazo compound of dianotated 4-amirroacetariilide-3-sulfonic acid and 1-amir) o-2-oxyriaphtalin-oxyith3-ether @ sulfuric acid ester is used with the condensate cation product of molar amounts of cyanuric chloride,
1-Ethylamino-8-oxynaphthalene-3.6-disulfosärrre, 4-amino-4'-oxyazobenzene-2.3'-dicarboxylic acid and 4-methyl-1-thiopherrole kup pelt.
<I> Example </I> The diazo compound prepared in a known manner from 524 parts by weight of the azo dye from 4-aminoacetanilide-3-sulfonic acid and 1-amino-2-oxynaphthalene-oxethylsulfuric acid ester of the formula:
EMI0001.0027
is pasted with ice water and added to the solution of the condensation product of molar amounts of cyanuric chloride, 1-ethylamino-8-oxynaphthalicr-3,6-disulfonic acid, 4-amirro-4'-oxyazoben-zol-2. 3'-dicarboxylic acid and 4-methyl-1-thiophenol added at 5-10.
The dye, processed as usual, is a dark, shiny bronze powder when dry, which dissolves in water with a green color and draws from the Glauber's salt soda bath in bright green shades of very good lightfastness onto the vegetable fiber.
