Die Amidoazofarbstoffe derThe amidoazo dyes of

allgemeinengeneral
N=N-R' (wobei N = NR ' (where
unter R1 die Reste von gekuppelten Dioxynaphtalinsulfosäuren zu verstellen sind) werden beim Behandeln mit Benzylchlorid oder analogen Benzylverbindungen in Gegenwart von Alkalien glatt in die entsprechenden Benzylfarbstoffe übergeführt, welche technisch wichtige Vorzüge gegenüber den Ausgangsproducten besitzen.under R 1, the residues of coupled dioxynaphthalene sulfonic acids are to be adjusted) are converted smoothly into the corresponding benzyl dyes on treatment with benzyl chloride or analogous benzyl compounds in the presence of alkalis, which have technically important advantages over the starting products.
Letztere können auf bekannte Weise erhalten werden, wenn man z. B. die Acetylverbindungen von Diaminen bezw. substituirten Diaminen diazotirt, dann die resultirenden Diazoproducte mit Dioxynaphtalinsulfosäuren kuppelt und hierauf die Acetylgruppe abspaltet, oder wenn man, ausgehend von Mononitroverbindungen der Amine bezw. substituirten Amine, deren Diazoderivate mit Dioxynaphtalinsulfosäuren combinirt und nach beendigter Kuppelung die Nitrogruppe durch geeignete Reductionsmittel in die Amidogruppe überführt.The latter can be obtained in a known manner by e.g. B. the acetyl compounds of diamines respectively. substituted diamines are diazotized, then the resulting diazo products couples with dioxynaphthalene sulfonic acids and then splits off the acetyl group, or if one, starting from mononitro compounds of the amines BEZW. substituted amines, their Diazo derivatives combined with dioxynaphthalene sulfonic acids and, after coupling is complete, the Nitro group converted into the amido group by suitable reducing agents.
Von den genannten Ausgangsproducten liefern besonders diejenigen werthvolle Resultate, welche in obigerWeise ausMonoacetyl-p-phenylendiamin bezw. p-Nitranilin und den Sulfosäuren des Ci1 a4-Dioxynaphtalins gewonnen werden.Of the starting products mentioned, particularly those which produce valuable results in the above manner from monoacetyl-p-phenylenediamine and / or. p-Nitraniline and the sulfonic acids of Ci 1 a 4 -Dioxynaphtalins are obtained.
Das Verfahren zur Herstellung dieser neuen Farbstoffe erfolgt allgemein in der Weise, dafs man 1 Molecül der zunächst gebildeten Amidoazopröducte mit 1 Molecül Benzylchlorid bezw. einer analogen Benzylverbindung und 1 Molecül Alkali bezw. Y2 Molecül Alkalicarbonat behandelt.The process for the preparation of these new dyes is generally carried out in such a way that 1 Molecül of the amidoazo products initially formed with 1 Molecül benzyl chloride respectively. an analogous benzyl compound and 1 Molecül alkali BEZW. Y 2 Molecül alkali carbonate treated.

38,1 kg des aus Acetyl-p-phenylendiamin durch Diazotiren, Kuppeln mit αΎ ct4-Dioxynaphtalin-a3-monosulfosäure und Abspalten der Acetylgruppe erhältlichen Farbstoffs werden in Wasser gelöst. Nach Zusatz von 12,7 kg Benzylchlorid und 7 kg Potasche schüttelt bezw. rührt man unter gelindem Erwärmen, bis der Geruch des Benzylchlorids vollständig verschwunden ist. Der schwerlösliche Farbstoff wird durch Abfiltriren, Pressen und Trocknen isolirt. Er färbt Wolle in saurem Bade dunkelblau.38.1 kg of the dye obtainable from acetyl-p-phenylenediamine by diazotiring, coupling with α Ύ ct 4 -dioxynaphthalene-a 3 -monosulfonic acid and cleavage of the acetyl group are dissolved in water. After adding 12.7 kg of benzyl chloride and 7 kg of Potasche shakes respectively. The mixture is stirred with gentle warming until the odor of the benzyl chloride has completely disappeared. The sparingly soluble dye is isolated by filtering off, pressing and drying. He dyes wool dark blue in an acid bath.
In ähnlicher Weise erhält man die anderen Farbstoffe, wenn man an Stelle des in vorstehendem Beispiele benutzten Amidoazoproductes die analogen Amidoazoverbindungen aus Ci1 a4-Dioxynaphtalin-a2ßj-disulfosäure bezw. Ct1 a4 - Dioxynaphtalin - ß2 ß3 - disulfosäure verwendet. The other dyes are obtained in a similar manner if, instead of the amidoazo products used in the preceding examples, the analogous amidoazo compounds from Ci 1 a 4 -dioxynaphthalene-a 2 βj-disulfonic acid or. Ct 1 a 4 - dioxynaphthalene - ß 2 ß 3 - disulfonic acid used.
Dieselben erzeugen auf Wolle in saurem Bade rein blaue Nuancen.These produce pure blue nuances on wool in an acidic bath.
An Stelle des Benzylchlorids (1 Molecül) kann man natürlich Benzylbromid oder ähnliche Benzylirungsmittel, an Stelle von Potasche (Y2 Molecül) lassen sich andere Alkalicarbonate (Y2 Molecül) oder auch Aetzalkalien (1 Molecül) verwenden.In place of the benzyl chloride (1 molecule) one can of course use benzyl bromide or similar benzylating agents, instead of potash (Y 2 molecule) other alkali metal carbonates (Y 2 molecule) or caustic alkalis (1 molecule) can be used.
Die so entstehenden Farbstoffe stellen Gemische von den in der französischen Patent-The resulting dyes represent mixtures of the in the French patent
