Verfahren zur Darstellung gelber Farbstoffe.
Es wurde gefunden, dass man durch Kuppeln der Tetrazoverbindungen des Diaminotriphenylmethans bzw. dessen Derivaten mit Pyrazolon und dessen Derivaten durch ihre reine Gelbnuance ausgezeichnete Farbstoffe erhält, die sowohl für die Woll- und Seidenfärberei als auch für die Farblackherstellung wertvoll sind.
Die Darstellung der neuen Farbstoffe geschieht, z. B. wie folgt :.
I. Die in iiblicher Weise aus 274#3 kg Diaminotriphenylmethan hergestellte Tetrazoverbindung lässt man in eine mittels Natronlauge und Soda hergestellte wässerige Lösung von 417 leg 1- (2-Chlorphenyl)-3-methyl-5-pyrazolon einlaufen. Nach beendeter Kupplung wird der Farbstoff in üblicher Weise isoliert. Die Kupplung kann eventuell auch in essigsaurer Lösung durchgeführt werden.
II. Die aus 274 kg Diaminotriphenylmethan hergestellte Tetrazoverbindung wird mit einer sodaalkalischen Lösung von 577'5 kg 1- (2 Chlor-5-sulfophenyl) -3-methyl-5-pyrazolon vereinigt.
EMI1.1

Process for the preparation of yellow dyes.
It has been found that coupling the tetrazo compounds of diaminotriphenylmethane or its derivatives with pyrazolone and its derivatives gives excellent dyes due to their pure yellow shade, which are valuable both for wool and silk dyeing and for the manufacture of colored varnishes.
The presentation of the new dyes happens, for. B. as follows:.
I. The tetrazo compound, prepared in the usual way from 274 × 3 kg of diaminotriphenylmethane, is allowed to run into an aqueous solution of 417 μg of 1- (2-chlorophenyl) -3-methyl-5-pyrazolone prepared using sodium hydroxide solution and soda. After the coupling has ended, the dye is isolated in the customary manner. The coupling can possibly also be carried out in acetic acid solution.
II. The tetrazo compound produced from 274 kg of diaminotriphenylmethane is combined with a soda-alkaline solution of 577,5 kg of 1- (2 chloro-5-sulfophenyl) -3-methyl-5-pyrazolone.
EMI1.1
pure greenish yellow shade, which is characterized by excellent mill, sulfur and lightfastness.
