Description
Verfahren zur Darstellung eines ltlonoazofarbstoffes. In weiterer Ausbildung des Verfahrens des Hauptpatentes wurde gefunden, dass man durch Kuppeln der Diazoverbindung aus m-Amidobenzaldehyd mit einem Molekül 1- (5'-sulfo-3'-carboxy-2'-oxy) -phenyl-3 -me- thyl-5-pyrazolon einen noch die freie Al- dahydgruppe enthaltenden Monoazofarbstoff erhält, welcher als Pigmentfarbstoff sehr geeignet ist, aber auch die tierische Faser aus saurem Bade in sehr klaren grüngelben, alkali-,
wasser-, wasch-, walk- und lichtechten Tönen anfärbt. Durch Nachchromieren wird die Färbung dunkler und übertrifft dann das bekannte Beizengelb 0 sowohl im Grün stich der Nuance, als auch ganz besonders in der Karbonisierechtheit. Der Farbstoff eignet sich auch zum Wolldruck.
Natriumnitrit in 150 Liter Wasser bei 0 bis 5 diazotiert worden ist, wird, wie üblich, mit einer Lösung von 94,2 kg 1- (5'- sulf o -3'- carboxy -2'- oxy) - phenyl -3 - me- thyl-5-pyrazolon ,in 600 Liter Wasser und 40 kg calcinierter Soda bei 0 bis 5 gekup pelt. Die Farbstoffbildung tritt sofort ein und ist nach kurzem Nachrühren bei 20 bis <B>25'</B> beendet.
Der Farbstoff wird durch Koch salz vollständig ausgesalzen, filtriert, ge waschen und getrocknet.
Process for the preparation of an itlonoazo dye. In a further development of the process of the main patent, it was found that by coupling the diazo compound from m-amidobenzaldehyde with a molecule of 1- (5'-sulfo-3'-carboxy-2'-oxy) -phenyl-3-methyl- 5-pyrazolone contains a monoazo dye which still contains the free aldehyde group, which is very suitable as a pigment dye, but also the animal fibers from acid baths in very clear green-yellow, alkaline,
dyes water-, wash-, mill- and lightfast shades. After chrome plating, the color becomes darker and then surpasses the well-known stain yellow 0, both in terms of the shade of green and especially in terms of its fastness to carbonization. The dye is also suitable for wool printing.
Sodium nitrite has been diazotized in 150 liters of water at 0 to 5, is, as usual, with a solution of 94.2 kg 1- (5'-sulf o -3'-carboxy -2'-oxy) - phenyl -3 - methyl-5-pyrazolone, in 600 liters of water and 40 kg of calcined soda at 0 to 5 pelt. The dye formation occurs immediately and is complete after brief stirring at 20 to 25 '.
The dye is completely salted out with sodium chloride, filtered, washed and dried.
