Description
Zusatzpatent zum Hauptpatent Nr.<B>123169.</B> Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff et-hält, wenn man den Azofarb- stoff, welcher erhalten werden kann durch Vereinigen eines dianotierten und an der OH-Gruppe acidylierten Derivates der 1,8- Aminonaphthol-3,6-disulfosäure mit Kresidin (CH. i: OCHS :
NH2 = 1 :4:3), ein Verseifungs- mittel, Phosgen und den Azofarbstoff, der erhalten werden kann durch Vereinigen der dianotierten 2,8-Aminonaphthol-6-sulfosäure mit Kresidin (CH3.: OCH3 : NH2 = 1 : 4 : 3), aufeinander einwirken lässt und so zu einem Harnstoffderivat verkettet.
Der neue Farbstoff bildet ein braunrotes Pulver; er färbt unge- beizte Baumwolle in sehr egalen, roten Tönen von sehr guter Lichtechtheit. <I>Beispiel:</I> 62,1 Teile des Farbstoffes aus' dem diano tierten p-Toluolsulfosäureester der 1,8-Amino- naphthol - 3,6 - disulfosäure und Kresidin (CH3 : OCH3 : NH2 = 1 : 4 :
3), sowie 38,7 Teile des Farbstoffes aus dianotierter 2,8- Aminonaphthol - 6 - sulfosäure und Kresidin <B>(CM</B> : OCHS : NH2 = 1: 4 : 3) werden in soda- alkalischer Lösung bei 30 o erschöpfend mit Phosgen behandelt und das erhaltene Harn stoffderivat mit 3 o/oiger Natronlauge bei 90 0 verseift. Der neue Farbstoff wird in bekannter Weise isoliert.
Der gleiche Farbstoff entsteht auch, wenn man den Farbstoff aus dem Ester der 1,8- Aminonaphthol-3,6-disulfosäure zunächst ver seift und dann mit dem zweiten Azokörper vereinigt.
Additional patent to main patent no. <B> 123169. </B> Process for the production of a new dye. It has been found that a new azo dye is retained if the azo dye, which can be obtained by combining a dianotated derivative of 1,8-aminonaphthol-3,6-disulfonic acid with cresidine, and acidylated at the OH group, is found (CH. I: OCHS:
NH2 = 1: 4: 3), a saponifying agent, phosgene and the azo dye, which can be obtained by combining the dianotated 2,8-aminonaphthol-6-sulfonic acid with cresidine (CH3 .: OCH3: NH2 = 1: 4: 3), can act on each other and thus linked to a urea derivative.
The new dye forms a brownish red powder; it dyes unstained cotton in very even, red shades of very good lightfastness. <I> Example: </I> 62.1 parts of the dye from the diano-tated p-toluenesulfonic acid ester of 1,8-amino naphthol - 3,6 - disulfonic acid and cresidine (CH3: OCH3: NH2 = 1: 4:
3), and 38.7 parts of the dye from dianotized 2,8-aminonaphthol-6-sulfonic acid and cresidine (CM: OCHS: NH2 = 1: 4: 3) are added in a soda-alkaline solution 30 o treated exhaustively with phosgene and the urea derivative obtained saponified with 3 o / o sodium hydroxide solution at 90 °. The new dye is isolated in a known manner.
The same dye is also formed when the dye from the ester of 1,8-aminonaphthol-3,6-disulfonic acid is first soaped and then combined with the second azo body.
