Description
<Desc/Clms Page number 1>
Verfahren zur Darstellung eines Gallocyaninfarbstoffs.
Es wurde gefunden, dass man durch Einwirkung von p-Nitroso-m-chlordiäthylanilin auf Gatlaminsnuro zu einem wertvollen Gallocyaninfarbstoff gelangt, der sich vor dem analogen halogenfreien Produckt, dem Gölestinblan, durch seine wertvollen grüneren klaren Nuancen auszeichnet.
Beispiel.
17 kg Gallaminsäure und 37 kg salzsaures p-Nitroso-m-chlordiäthylanilin werden mit 250 1 Alkohol angerührt und die so erhaltene Masse so lange im Wasserbade erhitzt, bis die Nitrosoverbindnng verschwunden ist. Der ausgeschiedene Farbstoff wird darauf abfiltriert und mit Wasser gewaschen. Der neue Körper bildet ein dunkles Pulver, das sich in konzentrierter Schwefelsäure mit violetter Farbe auflöst. Er wird zur Verwendung im Druck in bekannter Weise mit Hilfe von Natriumbisulfit in seine lösliche Leukoverbindung übergeführt und liefert so mit essigsaurem Chrom gedruckt grünstichig blaue klare Nüancen.
Das p-Nitroso-m-chlordiäthylanilin stellt in Form der freien Base ein dunkelgrünes Pulver dar. das sich in Alkohol mit gelber Farbe auflöst. Es schmilzt bei 76 bis 7 ; 0.

Process for preparing a gallocyanine dye.
It has been found that the action of p-nitroso-m-chlorodiethylaniline on Gatlaminsnuro leads to a valuable gallocyanin dye which is distinguished from the analogous halogen-free product, the Gölestinblan, by its valuable greener clear nuances.
Example.
17 kg of gallamic acid and 37 kg of hydrochloric acid p-nitroso-m-chlorodiethylaniline are mixed with 250 liters of alcohol and the mass thus obtained is heated in a water bath until the nitroso compound has disappeared. The precipitated dye is then filtered off and washed with water. The new body forms a dark powder that dissolves in concentrated sulfuric acid with a purple color. For use in printing, it is converted into its soluble leuco compound in a known manner with the aid of sodium bisulfite and, when printed with chromium acetate, produces clear, greenish blue nuances.
The p-nitroso-m-chlorodiethylaniline is a dark green powder in the form of the free base. It dissolves in alcohol with a yellow color. It melts at 76 to 7; 0.
