Description
Verfahren zur Darstellung sekundärer Disazofarbstoffe. Es wurde gefunden, daß die sekundären hisazofarbstotte, die man erhält, wenn man unsulfierte oder stilfierte bzw. carboxylierte nionoacidylierte Phenylendiümine bzw. -Naphthylendiamine mit Aminonaphtholäthern oder Atninostilfonaphtholäthern kuppelt, weiterdiazotiert und mit i # g-Dioxviaphthaliiisttlfosäuren oder i # g- Ainiiionaphtholstilfosätiren oder ihren Derivaten vereinigt, wertvolle Eigenschaften für de Seidenfärberei besitzen. Sie zeichnen sich durch gute Egalisierungsfühigkeit, gute Wasserechtheit, klare grünflaue bis grüne Nuancen aus und weisen eine -tite Lichtechtheit auf. Außerdem besitzen sie eine gute Ätzbarkeit, so daß sie auch für den Ätzdruck seht- geeignet sind. Unter den iiionoacidvlierten Phenvlendiaminen sind auch die entsprechenden Harnstoffe zu verstehen. Beispiel. 23 Gewichtsteile 4-Acetylainitio-i-anilin-2-sulfosiitire werden neutral mit Soda in Wasser gelöst, mit Eis auf io° abgekühlt und mit 35 Gewichtsteilen roher Salzsäure und 6,9 Gewichtsteilen Nitrit dianotiert. Die Dianotierung läuft in eine mit Acetat versetzte Lösung von 26,; Gewichtsteilen i -Aniitio-2-naplitliol<ithyläther-6-stilfosiiur e. Das isolierte und wieder angeschlämmte Zwischenprodukt wird mit 56 Gewichtsteilcn Natronlauge (i6 Prozent) ins \atriumsalz fbergeführt und bei io° mit 69 Gewichtsteilen roher Salzsäure und 6,9 Gewichtsteilen Nitrit dianotiert. Die Dianotierung wird unter Salzzugabe isoliert, wieder angerührt und mit einer Lösung von 24 Gewichtsteilen Acetyl-i # g-aminonaphthol-4-suifosäure sodaalkalisch gekuppelt. Der Farbstoff wird in üblicher Weise isoliert. Auf Seide gefärbt, stellt er ein klares Grün dar, das sich durch vorzügliche Ätzbarkeit und sehr gute Lichtechtheit auszeichnet.Process for the preparation of secondary disazo dyes. It was found, that the secondary hisazo dyes obtained when unsulfurized or styled or carboxylated ionoacidylated phenylenediamines or naphthylenediamines with Aminonaphtholäthern or Atninostilfonaphtholäthern coupled, further diazotized and with i # g-Dioxviaphthaliiisttlfosäuren or i # g-Aliniiionaphtholstilfosätiren or their derivatives combined, have valuable properties for silk dyeing. They are characterized by good leveling ability, good water fastness, clear green-blue to green nuances and have a -tite lightfastness. aside from that they have good etchability, so that they are also suitable for etching printing are. The corresponding phenylenediamines are also included among the ionoacidated phenolic diamines Understanding ureas. Example. 23 parts by weight of 4-Acetylainitio-i-aniline-2-sulfosiitire are dissolved neutrally with soda in water, cooled to 10 ° with ice and with 35 parts by weight raw hydrochloric acid and 6.9 parts by weight of nitrite dianotized. Dianoting is in progress in an acetate added solution of 26; Parts by weight of i -Aniitio-2-naplitliol <ethyl ether-6-stilfosiiur e. The isolated and reslurried intermediate product is 56 parts by weight Sodium hydroxide solution (16 percent) converted into the atrium salt and at 10 ° with 69 parts by weight raw hydrochloric acid and 6.9 parts by weight of nitrite dianotized. The dianotation will isolated with addition of salt, stirred again and with a solution of 24 parts by weight Acetyl-i # g-aminonaphthol-4-suifoic acid coupled with alkaline soda. The dye will isolated in the usual way. Dyed on silk, it is a vivid green that is characterized by excellent etchability and very good lightfastness.
An Stelle der im Beispiel genannten 4.-Acetylainino-i-anilin-2-sulfosäure können auch andere acidylierte Phenylendiamine - oder Naphthylendiamine verwendet werden, wie z. B. m- oder p-Aininoacetänilid, 3-Acetylamino-i-aiiilin-6-stilfo-oder-carbonsätire, Benzoyl-p-pheny lendiamin-o-sulfosäure, 4.-Oxalylainino-i-anilin-3-su1fOsäure, p-Diaminodiphenylharnstoff bzw. seine Disulfosäure, -1Acetylnaphtliy lendiamiii oder seine 2-6-oder ;--'L\Zonosu1fos<iure. Als Mittelkomponenten können auch die i-Ainino-2-naphtlioläther-;-su1fOsäure und an Stelle der Äthylätlier die '.NZethvläther verwendet werden,Instead of the 4.-Acetylainino-i-aniline-2-sulfonic acid mentioned in the example Other acidylated phenylenediamines or naphthylenediamines can also be used become, such as B. m- or p-Aininoacetänilid, 3-Acetylamino-i-aiiilin-6-stilfo- or -carbonsätire, Benzoyl-p-phenylenediamine-o-sulfonic acid, 4.-Oxalylainino-i-aniline-3-sulfonic acid, p-diaminodiphenylurea or its disulfonic acid, -1-acetylnaphthylendiamiii or its 2-6- or; The i-ainino-2-naphthol ether -; - su1fOic acid and instead of the ethyl ethers the '.Nzethv ethers are used,
