Verfahren zur Darstellung eines Gallocyaninfarbstoffs.Process for the preparation of a gallocyanine dye.
Patentiert im Deutschen Reiche vom 22. Mai 1907 ab.Patented in the German Empire on May 22, 1907.
Es wurde gefunden, daß man durch Einwirkung von ρ -Nitroso- m-chlordiäthylanilin auf Gallaminsäure zu einem wertvollen Gallocyaninfarbstoff gelangt, der sich vor dem analogen halogenfreien Produkt, dem Cölestinblau, durch seine wertvollen grüneren klaren Nuancen auszeichnet.It has been found that the action of ρ -nitroso- m-chlorodiethylaniline on gallamic acid to a valuable gallocyanine dye which comes before the analogous halogen-free product, the cölestin blue, characterized by its valuable greener clear nuances.
17 kg Gallaminsäure und 37 kg salzsaures ρ-Nitroso-m-chlordiäthylanilin werden mit 250 1 Alkohol angerührt und die so erhaltene Masse so lange im Wasserbade erhitzt, bis die Nitrosoverbindung 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 Nuancen.17 kg of gallamic acid and 37 kg of hydrochloric acid ρ-nitroso-m-chlorodiethylaniline are with 250 1 alcohol and the resulting mass 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 turns into concentrated sulfuric acid with purple color. It is used in the Pressure in a known manner with the help of sodium bisulfite into its soluble leuco compound and thus delivers greenish blue clear nuances printed with acetic acid chrome.
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 770. The p-nitroso-m-chlorodiethylaniline is a dark green powder in the form of the free base, which dissolves in alcohol with a yellow color. It melts at 76 to 77 0 .
