Description
Verfahren zur Herstellung eines Azofarbstoi%s. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Azofarb- stoffes, dadurch gekennzeichnet, dass man die Diazoverhindung von N-(3-Aminobenzoyl)- N-,do dekahydro - diphenyl-2'-methyl - phenyl- amin mit 1-(2',5'-Dimethyl-4'-chlorbenzol- sulfoamino) - 8 -ogynaphthalin- 3,
6 - disulfon- säure vereinigt.
Der so erhaltene Farbstoff ist trocken ein rotes Pulver, dessen lebhafte rote Färbungen auf Wolle sehr gute Echtheitseigenschaften, insbesondere gegen Wäsche, Walke, Schweiss und Seewasser, sowie gute Lichtechtheit be sitzen.
Beispiel: 38,6 Teile N-(3-Aminobenzoyl)-N-dodeka- hydro - diphenyl-2'-methyl - phenylamin der Formel
EMI0001.0025
werden diazotiert und die Diazoverbindung wird in Gegenwart von überschüssigem Ätz- kalk mit 53 Teilen 1-(2',5'-Dimethyl-4'- chlorbenzol-sufoamino)- 8 -ogynaphthalin-3,6- disulfonsäure vereinigt.
Der Farbstoff wird dann in das Natriumsalz übergeführt und dieses abgeschieden und getrocknet.
Process for the production of an azo dye% s. The present patent relates to a process for the production of an azo dye, characterized in that the diazo compound of N- (3-aminobenzoyl) - N-, do decahydro - diphenyl-2'-methyl - phenyl amine with 1- ( 2 ', 5'-dimethyl-4'-chlorobenzenesulfoamino) - 8 -ogynaphthalene- 3,
6 - disulfonic acid combined.
The dyestuff thus obtained is a dry red powder, the vivid red colorations of which have very good fastness properties on wool, in particular against laundry, fulling, perspiration and seawater, and also good lightfastness.
Example: 38.6 parts of N- (3-aminobenzoyl) -N-dodecahydro-diphenyl-2'-methyl-phenylamine of the formula
EMI0001.0025
are diazotized and the diazo compound is combined with 53 parts of 1- (2 ', 5'-dimethyl-4'-chlorobenzene-sufoamino) -8 -ogynaphthalene-3,6-disulfonic acid in the presence of excess quicklime.
The dye is then converted into the sodium salt, which is deposited and dried.
