KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
In der Patentschrift Nr. 79208 wurde gezeigt, dafs man durch Einwirkung von Traubenzucker in alkalischer Lösung auf αχ α4-Dinitronaphtalin einen unlöslichen violetten metallglä'nzenden Körper erhält, der infolge seiner Unlöslichkeit in fast allen Lösungsmitteln als solcher keine gewerbliche Verwerthung gestattet; er mufs vielmehr direct auf der Faser erzeugt werden und giebt so auf Baumwolle violettschwarze bis schwarze Färbungen. Die Reaction verläuft ganz anders, wenn sie in -Gegenwart von Sulfiten oder Bisulfiten der Alkalien oder alkalischen Erden vorgenommen wird. In diesem Falle erhält man einen vollkommen wasserlöslichen Farbstoff, welcher ungeheizte Wolle in angesäuertem Bade in lebhaften violettblauen Tönen anfärbt.In the patent specification No. 79208 it was shown that by the action of glucose in alkaline solution on α χ α 4 -Dinitronaphtalin an insoluble violet metal-shining body is obtained, which, because of its insolubility in almost all solvents, does not permit any commercial use; Rather, it must be produced directly on the fiber, and so gives violet-black to black colorations on cotton. The reaction proceeds quite differently when it is carried out in the presence of sulphites or bisulphites of alkalis or alkaline earths. In this case, a completely water-soluble dye is obtained, which dyes unheated wool in an acidic bath in vivid violet-blue tones.
ι ο kg fein gemahlenes Ci1 a4 - Dinitronaphtalin, 800 1 Wasser, 10 kg Traubenzucker, 20 kg Natriumbisulfit 380B. und 20 kg Natronlauge 30B. werden so lange auf ca. 80° C. erwärmt, bis kein unverändertes Dinitronaphtalin mehr nachzuweisen ist. Dieser Punkt ist nach ca. zwei Stunden erreicht. Die Lösung, die eine prachtvolle blaue Farbe angenommen hat, wird nun mit 30 kg Salzsäure von 20° B. versetzt und so lange gekocht, bis keine schweflige Säure mehr entwickelt wird. Nun wird der Farbstoff mit Kochsalz oder Chlorkalium ausgesalzen, filtrirt, geprefst und getrocknet. Er bildet ein violettschwarzes, metallglänzendes Pulver, welches in kaltem Wasser mit rein violetter Farbe löslich ist.ι ο kg of finely ground Ci 1 a 4 - dinitronaphthalene, 800 l of water, 10 kg of grape sugar, 20 kg of sodium bisulfite 38 0 B. and 20 kg of sodium hydroxide 30B. are heated to approx. 80 ° C until no more unchanged dinitronaphthalene can be detected. This point is reached after about two hours. The solution, which has taken on a splendid blue color, is now mixed with 30 kg of hydrochloric acid at 20 ° B. and boiled until no more sulphurous acid is developed. The dye is then salted out with sodium chloride or potassium chloride, filtered, pressed and dried. It forms a violet-black, metallic-shimmering powder, which is soluble in cold water with a purely violet color.
