Verfahren zur Darstellung beizenfärbender Monoazofarbstoffe.Process for the preparation of stain-coloring monoazo dyes.
Zusatz zum Patent 263192.Addendum to patent 263192.
Patentiert im Deutschen Reiche vom 19. Mai 1914 ab. Längste Dauer: !.Februar 1927.Patented in the German Empire on May 19, 1914. Longest duration: February 1927.
Durch Patent 263192 ist ein Verfahren zur Darstellung beizenfärbender Monoazofarbstoffe durch Kuppelung diazotierter o-Aminophenolsulfosäure und ihrer Derivate mit i-Acidylamino-7-oxynaphtalinen geschützt. Als Acidylderivate, die für das Verfahren benutzt werden, führt die Beschreibung die Acetyl- und Benzoylverbindung an, also Derivate von Carbonsäuren. By patent 263192 there is a method of preparing mordant coloring monoazo dyes by coupling diazotized o-aminophenol sulfonic acid and their derivatives with i-acidylamino-7-oxynaphthalene protected. As acidyl derivatives used for the process, the description cites the acetyl and benzoyl compounds, i.e. derivatives of carboxylic acids.
Es wurde nun weiter gefunden, daß sich die Carbonsäurederivate durch entsprechende Derivate von Arylsulfosäuren ersetzen lassen, wobei Farbstoffe erhalten werden, die nicht nur die in der Patentschrift 263192 bezeichneten Vorzüge besitzen, sondern deren Färbungen einen noch grüneren Ton und erhöhte Walkechthcit aufweisen.It has now also been found that the carboxylic acid derivatives by corresponding Let derivatives of arylsulfonic acids be replaced, with dyes being obtained that are not only have the advantages specified in patent specification 263192, but their colors have an even greener tone and increased whale-fastness.
Die aus 22,4 Teilen 4-Chlor-2-amino-i-oxybenzol-6-sulfosäure und 6,9 Teilen Natriumnitrit in Gegenwart von Salzsäure bereitete Diazoverbindung läßt man unter Rühren und Kühlung in eine wäßrige Lösung von 32,8 Teilen i-Toluolsulfamino-7-oxynaphtalin in 24 Teilen Natronlauge von 400 Be, die mit 18,5 Teilen wasserfreiem Natriumcarbonat versetzt ist, einlaufen. Nach beendeter Kuppelung wärmt man an, salzt den Farbstoff aus und arbeitet ihn in der üblichen Weise auf. Er färbt Wolle in Gegenwart von Chrombeizen walkecht grünschwarz.The diazo compound prepared from 22.4 parts of 4-chloro-2-amino-i-oxybenzene-6-sulfonic acid and 6.9 parts of sodium nitrite in the presence of hydrochloric acid is allowed to pour into an aqueous solution of 32.8 parts of i- Toluenesulfamino-7-oxynaphthalene in 24 parts of 40 0 Be sodium hydroxide solution to which 18.5 parts of anhydrous sodium carbonate have been added. After coupling is complete, the dye is warmed up, salted out and worked up in the usual way. It dyes wool in the presence of chrome stains, green-black, fast-to-walk.
Andere o-Aminophenolsulfosäuren, z. B. die 4-Chlor-2-amino-i-oxybenzol-5-sulfosäure oder die 6-Nitro-2-amino-i-oxybenzol-4-sulfosäure, führen zu ähnlichen Ergebnissen.Other o-aminophenol sulfonic acids, e.g. B. the 4-chloro-2-amino-i-oxybenzene-5-sulfonic acid or 6-nitro-2-amino-i-oxybenzene-4-sulfonic acid, lead to similar results.
