Description
Verfahren zur Darstellung eines Polyazofarbstoifes. Es wurde gefunden, dass man einen wert vollen grünen Direktfarbstoff erhält, wenn man 1 Mol. der dianotierten Amirroazover- bindung aus 4-Toluidin-3-sulfosäure und di- azotierter 1-Amino-2-naphtolätlryläther-6-sul- fosäure mit 1 Mol. des Kondensationspro duktes aus molaren Mengen Cyanurchlorid, 1 .8-Aminonaphtol-3.6-disulfosäure,
Dehydro- thiotoluidinsulfosäure und 4-Amino-4'-ogyazo- benzol-3'-carbonsäure kuppelt.
<I>Beispiel:</I> Die in üblicher Weise aus 465 Gewichts- teilen des Aminoazofarbstoffes aus dianotierter 1-Amino-2-naphtoläthyläther-6-sulfosäure und 4-Toluidin-3-sulfosäure hergestellte, abgeschie dene und mit Eiswasser verpastete Diazo- verbindung fliesst bei 5 bis 10 zu einer gut gerührten, zweckmässig mit Pyridin versetzten Lösung von 1194 Gewichtsteilen des Kon densationsproduktes aus 1 Mol. Cyanurchlorid, 1 Mol. 1.8-Aminonaphtol-3.6-disulfosäure,
1 Mol. Dehydrothiotoluidin-3-sulfosäure und 4-Amino-4'-ogyazobenzol-3'-carbonsäure von der Formel:
EMI0001.0033
Die Kupplung setzt sofort unter Tiefgrün färbung der Lösung ein und ist bald be endigt.
Der Farbstoff stellt in getrocknetem Zu stand ein dunkles, bronzeglänzendes Pulver dar, das sich mit grüner Farbe in Wasser löst und aus dem Glaubersalz-Sodabad in kräftigen grünen Farbtönen von grosser Rein heit auf die pflanzliche Faser aufzieht. Die Färbungen besitzen eine sehr gute Licht echtheit.
Process for the preparation of a polyazo dye. It has been found that a valuable green direct dye is obtained if 1 mol. Of the dianotated amirroazo compound of 4-toluidine-3-sulfonic acid and diazoated 1-amino-2-naphtholethyl ether-6-sulfonic acid with 1 Mol. Of the condensation product from molar amounts of cyanuric chloride, 1,8-aminonaphthol-3,6-disulfonic acid,
Dehydrotothiotoluidinsulfonic acid and 4-amino-4'-ogyazobenzene-3'-carboxylic acid couples.
<I> Example: </I> The diazo prepared in the usual way from 465 parts by weight of the aminoazo dye from dianotated 1-amino-2-naphtholethyl ether-6-sulfonic acid and 4-toluidine-3-sulfonic acid, deposited and pasted with ice water - Compound flows at 5 to 10 to a well-stirred solution of 1194 parts by weight of the condensation product of 1 mol. cyanuric chloride, 1 mol. 1,8-aminonaphthol-3,6-disulfonic acid, suitably mixed with pyridine,
1 mol. Dehydrothiotoluidine-3-sulfonic acid and 4-amino-4'-ogyazobenzene-3'-carboxylic acid of the formula:
EMI0001.0033
The coupling starts immediately with a deep green coloration of the solution and is soon ended.
When dry, the dye is a dark, bronze-shimmering powder that dissolves in water with a green color and is absorbed from the Glauber's salt soda bath in strong green shades of great purity on the vegetable fiber. The colors have very good light fastness.
