Description
Verfahren zur Herstellung eines Monoazofarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines DZonoazofarb- stoffes, dadureh gekennzeichnet, dass man die Diazoverbindung von 1-n-Butylacetylamino- 4-aminobenzol mit 1-(2'-Chlorpbenogyacetyl- ainino)-8-naphthol-4.6-disulfosäure kuppelt.
Er bildet ein rotes wasserlösliches Pulver, das Wolle und Seide in leuchtenden Schar lachtönen von sehr guter Wasch-, Walk- und Lichtechtheit färbt.
Beispiel: 20,6 kg 1-n-Butylacetylamiiro-4-amino- benzol werden dianotiert. Die erhaltene Diazo- lösung lässt man in eine überschüssige Soda enthaltende Lösung von 50 kg 1-(2'-Chlor- pherio%yacetylamino)-8-n aphthol - 4 . 6 - disulfo- aäure laufen. Der so erhaltene Farbstoff wird durch Anwärmen und Aussalzen isoliert, fil triert und getrocknet.
Process for the preparation of a monoazo dye. The present patent relates to a process for the preparation of a D-zonoazo dye, characterized in that the diazo compound of 1-n-butylacetylamino-4-aminobenzene is mixed with 1- (2'-chloropbenogyacetyl-ainino) -8-naphthol-4,6-disulphonic acid clutch.
It forms a red, water-soluble powder that dyes wool and silk in brilliant shades of laughing shades of very good wash, milled and lightfastness.
Example: 20.6 kg of 1-n-butylacetylamiiro-4-aminobenzene are dianotized. The diazo solution obtained is immersed in a solution of 50 kg of 1- (2'-chloropherio% yacetylamino) -8-naphthol -4 containing excess soda. 6 - run disulfo acid. The dye obtained in this way is isolated by heating and salting out, filtered and dried.
