Patentiert im Deutschen Reiche vom 17. April 1907 ab. Patented in the German Empire on April 17, 1907 .
In der Patentschrift 135015 ist ein Verfahren zur Darstellung alkylierter Monoazofarbstoffe beschrieben, welches darin besteht, daß man zunächst den Nitroazofarbstoff ausIn patent 135015 is a method described for the preparation of alkylated monoazo dyes, which consists in that you first off the nitroazo dye
. 5 o-Chlor-p-nitranilin und 1· 8-Dioxynaphtha-Hn-3 · 6-disulfosäure (Chromotropsäure) herstellt, den so gewonnenen Nitroazofarbstoff mit Schwefelnatrium reduziert und den dabei resultierenden Aminoazofarbstoff schließlich mit Alkylierungsmitteln, wie Brpmäthyl, behandelt. Wie in' der Patentschrift hervorgehoben wird, werden so Monoalkylderivate gewonnen.. 5 o-chloro-p-nitroaniline and 1x8-dioxynaphtha-Hn-3 Produces 6-disulfonic acid (chromotropic acid), the nitroazo dye obtained in this way is reduced with sodium sulphide and the resulting aminoazo dye finally treated with alkylating agents such as bromethyl. As highlighted in 'the patent specification is, so monoalkyl derivatives are obtained.
Es wurde nun gefunden, daß man in wesentlich einfacherer Weise zu den in jener Patentschrift nicht beschriebenen dialkylierten Monoazofarbstoffe^ gelangt, wenn man die Diazoverbindungen der bisher unbekannten p-Amino-m-chlordialkylaniline mit Chromotropsäure . kuppelt. Die erwähnten neuen Basen werden leicht erhalten, indem man die Nitrosoverbindungen der m-Chlordialkylaniline mit Zinkstaub und Salzsäure reduziert.It has now been found that it is much easier to get to those in that Dialkylated monoazo dyes not described in patent specification ^ arrives if you the Diazo compounds of the previously unknown p-amino-m-chlorodialkylanilines with chromotropic acid . clutch. The new bases mentioned are easily obtained by adding the Nitroso compounds of m-chlorodialkylanilines reduced with zinc dust and hydrochloric acid.
Das p- Amino-m-chlordimethylanilin bildet weiße Kristalle, die sich an der Luft bald grau färben. Schmelzpunkt 420, Siedepunkt 1580 bei 15 mm. Es ist schwer löslich in Wasser und leicht löslich in Säuren und organischen Lösungsmitteln.The p-amino-m-chlorodimethylaniline forms white crystals that soon turn gray when exposed to air. Melting point 42 0 , boiling point 158 0 at 15 mm. It is sparingly soluble in water and easily soluble in acids and organic solvents.
Das p-Amino-m-chlordiäthylanilin ist eine wasserhelle Flüssigkeit, die beim Stehen braun wird. Siedepunkt 285 ° bei 760 mm. Es ist schwer löslich in Wasser, leicht löslich in Säuren und organischen Lösungsmitteln.The p-amino-m-chlorodiethylaniline is one water-white liquid that turns brown when standing. Boiling point 285 ° at 760 mm. It is Slightly soluble in water, easily soluble in acids and organic solvents.

17 kg p-Amino-m-chlordimethylanilin werden mit Hilfe von 40 kg Salzsäure und 6,9 kg Natriumnitrit in üblicher Weise diazotiert. Die so erhaltene Diazoverbindung wird darauf zu einer gut gekühlten Lösung von 36,2 kg Chromotropsäure (neutrales Natronsalz) in 360 1 Wasser und 8 kg Natronhydrat züge-. fügt. Man gibt darauf noch 40 kg Natronlauge von' 25 Prozent hinzu. Nach kurzer Zeit ist die Kuppelung beendet. Nach dem Ansäuern mit Salzsäure fällt der Farbstoff aus, er wird abgesaugt und getrocknet. Er färbt Wolle in sehr lebhaften reinblauen, licht- und alkaliechten Tönen an.17 kg of p-amino-m-chlorodimethylaniline will be diazotized in the usual way using 40 kg of hydrochloric acid and 6.9 kg of sodium nitrite. The diazo compound thus obtained then becomes a well-cooled solution of 36.2 kg Chromotropic acid (neutral sodium salt) in 360 l of water and 8 kg of sodium hydrate. adds. 40 kg of caustic soda are then added of '25 percent added. The coupling is finished after a short time. After this Acidification with hydrochloric acid precipitates the dye, it is filtered off with suction and dried. He colors wool in very lively, pure blue, light and alkali-proof tones.
Vor dem in dem erloschenen Patent 74738 beschriebenen Farbstoff aus unchloriertem p-Aminodimethylanilin zeichnet sich das neue Produkt durch wesentlich größere Alkaliechtheit und schönere Nuance aus. Auch verläuft die Farbstoffkuppelung bei der Anwendung der chlorierten Basen wesentlich glatter und mit viel besserer Ausbeute.Before that in the expired patent 74738 described dye from unchlorinated p-aminodimethylaniline is characterized by the new one Product is characterized by its significantly greater alkali fastness and nicer nuance. Also runs the dye coupling when using the chlorinated bases is much smoother and with much better yield.
Der Farbstoff aus p-Amino-m-chlordiäthylanilin färbt Wolle ebenfalls blau.The dye from p-amino-m-chlorodiethylaniline also dyes wool blue.
