Patentirt im Deutschen Reiche vom 24. Februar 1895 ab.Patented in the German Empire on February 24, 1895.
In der Patentschrift Nr. 81963 ist ein Verfahren zur Darstellung von rothen bis violetten Azinfarbstoffen beschrieben, welches darin besteht, dafs man ρ-Nitrosoverbindungen der secundären und tertiären aromatischen Amine ζ. B. auf Phenyl-p-amido-o-toluidin der FormelIn patent specification no. 81963 is a method for displaying from red to purple Azine dyes described, which consists in the fact that ρ-nitroso compounds of the secondary and tertiary aromatic amines ζ. B. on phenyl-p-amido-o-toluidine of the formula

Es wurde nun gefunden, dafs man zu Producten von ähnlichen tinctoriellen Eigenschaften gelangt, wenn man an Stelle des phenylirten das entsprechende benzylirte p-Amido-o-toluidin (Benzyl-m-toluylendiamin) der FormelIt has now been found that products of similar tinctorial properties can be obtained if instead of the phenylated one the corresponding benzylated p-amido-o-toluidine is obtained (Benzyl-m-toluenediamine) of the formula

Die so erhaltenen Producte weisen die gleiche Klarheit und die vorzüglichen Echtheitseigenschaften (Alkali-, Licht-, Waschechtheit) auf, wie die Farbstoffe des Patentes Nr. 81963, zeichnen sich aber vortheilhaft vor diesen durch eine viel leichtere Löslichkeit aus.The products obtained in this way have the same clarity and excellent fastness properties (alkali, light, wash fastness) like the dyes of Patent No. 81963, but are advantageously distinguished from them a much easier solubility.
27 kg salzsaures Nitrosodimethylanilin werden zusammen mit 21 kg o-Amidomonobenzyl-ptoluidin in 100 kg Eisessig gelöst und einige Stunden im Wasserbade erhitzt. Die rothe Lösung wird dann in viel heifses Wasser gegossen, mit Ammoniak schwach alkalisch gemacht und filtrirt. Das Filtrat wird mit Salzsäure angesäuert und der Farbstoff mit Chlorzink und Kochsalz niedergeschlagen; er färbt tannirte Baumwolle rothviolett.27 kg of hydrochloric acid nitrosodimethylaniline together with 21 kg of o-amidomonobenzyl-ptoluidine dissolved in 100 kg of glacial acetic acid and heated in a water bath for a few hours. The red The solution is then poured into plenty of hot water and made weakly alkaline with ammonia and filtered. The filtrate is acidified with hydrochloric acid and the dye with Zinc chloride and common salt precipitated; he dyes tannic cotton red-violet.
In analoger Weise werden die Farbstoffe aus den anderen Nitrosoverbindungen gewonnen. The dyes are obtained from the other nitroso compounds in an analogous manner.
Der Farbstoff aus Nitrosomonomethyl-otoluidin färbt tannirte Baumwolle roth an, während der Farbstoff aus Nitrosodiäthylanilin auf der gleichen Faser rothviolette Töne giebt.The dye from nitrosomonomethyl-otoluidine stains tannic cotton red, while the dyestuff from nitrosodiethylaniline gives red-violet tones on the same fiber.
