. KLASSE 22: Farbstoffe, Firnisse, Lacke.. CLASS 22: dyes, varnishes, lacquers.
Patentirt im Deutschen Reiche vom 22. Oktober 1895 ab.Patented in the German Empire on October 22, 1895.
In der Patentschrift Nr. 56991 ist ein blauer Farbstoff beschrieben, welcher erhalten wird durch Einwirkung von Anilin . auf das Condensationsproduct von Nitrosodimethylanilin und Tanninanilid und nachheriges Sulfuriren.In patent specification No. 56991 there is a blue one Described dye which is obtained by the action of aniline. on the condensation product of nitrosodimethylaniline and tannin anilide and subsequent sulfurization.
Es hat sich nun gezeigt, dafs genannter Farbstoff sich leicht nitriren läfst und dafs durch Eintritt von Nitrogruppen die Nuance nach Grün hin verschoben wird. Das Mononitroderivat färbt chromirte Wolle in lebhaft grünen echten Tönen an, welche die bis jetzt bekannten Echtgrün an Schönheit der Nuance übertreffen. Durch Einführung von mehreren Nitrogruppen erhält man gelbstichigere, jedoch weniger lebhafte Nuancen.It has now been shown that the dye mentioned can be easily nitrided and passed through Entry of nitro groups the shade is shifted towards green. The mononitro derivative stains chrome-plated wool in vivid green real tones, which are known up to now Real green surpass the beauty of the shade. By introducing several Nitro groups give more yellowish, but less lively nuances.
20 kg des anilidirten Condensationsproductes von Nitrosodimethylanilin mit Tanninanilid werden während 4 bis 5 Stunden unter beständigem Umrühren in 100 kg 92 procentiger Schwefelsäure eingetragen. Darauf wird langsam auf 80 bis 85° C. erwärmt und das SuI-furirungsgemich so lange auf dieser Temperatur erhalten, bis eine Probe sich in alkalischem Wasser löst, welches Stadium in ι ο bis 15 Minuten eingetreten ist. Das Reactionsproduct wird nun auf 00C. abgekühlt und langsam mit einer Mischung von 2,4 kg 86.6 procentiger Salpetersäure und 6 kg 96 procentiger Schwefelsäure versetzt, indem man Sorge trägt, dafs während der Nitrirung die Temperatur nicht über 100C. steigt. Nach 10- bis 12stündigem Stehen bei gewöhnlicher Temperatur wird in Wasser gegossen, die Nitrosäure, die in Wasser unlöslich ist, abfiltrirt, gewaschen und in das wasserlösliche Ammoniaksalz übergeführt. 20 kg of the anilidized condensation product of nitrosodimethylaniline with tannin anilide are introduced into 100 kg of 92 percent sulfuric acid for 4 to 5 hours with constant stirring. The mixture is then slowly heated to 80 to 85 ° C. and the liquid is kept at this temperature until a sample dissolves in alkaline water, which stage has occurred within 15 minutes. The Reactionsproduct is then cooled to 0 0 C. and treated slowly with a mixture of 2.4 kg 86.6 procentiger nitric acid and 6 kg of sulfuric acid 96 procentiger by wearing concern, that does not exceed 10 0 C. increases during the nitration temperature. After standing for 10 to 12 hours at ordinary temperature, it is poured into water, the nitro acid, which is insoluble in water, is filtered off, washed, and converted into the water-soluble ammonia salt.
Der Farbstoff löst sich in Wasser mit blau-' grüner Farbe, die Lösung in concentrirter Schwefelsäure ist carmoisinroth.The dye dissolves in water with a blue- 'green color, the solution in a more concentrated form Sulfuric acid is carmoisine red.
