Zur Darstellung des Farbstoffs verfährt man z. B. folgendermafsen:To represent the dye one proceeds, for. B. as follows:
' Die aus 500 kg Schwefelnatrium, 500 1 Wasser und 65 kg Schwefel erhaltene Natriumdisulfidlösung wird mit 2000 1 Wasser verdünnt und unter Umrühren mit 200 kg α1 α4 - Dinitronaphtalin langsam versetzt. Durch gelindes Erwärmen wird die Temperatur auf 300 gebracht; sie steigt dann durch die eintretende Reaction allmählich auf 500. Nach 1- bis 2 stündigem Rühren und Belassen auf dieser Temperatur ist kein unverändertes Dinitronaphtalin mehr vorhanden.The sodium disulfide solution obtained from 500 kg of sodium sulphide, 500 l of water and 65 kg of sulfur is diluted with 2000 l of water and, while stirring, 200 kg of α 1 α 4 -dinitronaphthalene are slowly added. The temperature is brought to 30 0 by gentle heating; it then rises through the entering reaction gradually to 50 0th After stirring for 1 to 2 hours and leaving it at this temperature, there is no longer any unchanged dinitronaphthalene present.
Die rothe Lösung wird fütrirt und kalt mit 500 kg einer ca. 38 proc. Natriumbisulfitiösung versetzt. Die intensiv rothe Lösung geht rasch in gelbbraun über. Nach ca. 12 stündigem Stehen ist sie blau geworden, wird mit 120 kg Salzsäure versetzt und auf 60 bis 8o° erhitzt. Der Farbstoff scheidet sich als blauer Niederschlag ab, der abfiltrirt' und gewaschen wird. In Lösung bleibt in geringer Menge ein blauvioletter Farbstoff, der aufserordentlich leicht löslich und durch Kochsalz nicht fällbar ist.The red solution is fed and cold with 500 kg of an approx. 38 per cent. Sodium bisulfite solution offset. The intensely red solution quickly turns yellow-brown. After about 12 hours Standing it has turned blue, is mixed with 120 kg of hydrochloric acid and heated to 60 to 80 °. The dye separates out as a blue precipitate, which is filtered off and washed. A small amount of a blue-violet dye remains in solution, which is extraordinarily light is soluble and cannot be precipitated by table salt.
Die Eigenschaften des neuen Farbstoffs ergeben sich aus folgender Tabelle:The properties of the new dye are shown in the following table:
in engl. Schwefelsäure mit blaugrüner Farbe leicht löslich,in engl. Sulfuric acid with a blue-green color easily soluble,
in verdünnter Soda- und Schwefelnatriumlösung .... leicht löslich mit blauer Farbe, in verdünnter Natronlauge leicht löslich mit violetter Farbe. ·in dilute soda and sulfur sodium solution .... easily soluble with a blue color, Easily soluble in dilute sodium hydroxide solution with a violet color. ·
Die mit diesem Farbstoff erzielten Färbungen sind aufserordentlich beständig.The colorations achieved with this dye are extremely stable.
Ein aus αλ c.4-Dinitronaphtalin, Schwefelnatrium und Natriumbisulfit entstehender Farbstoff ist bereits durch das Patent 92471 der Badischen Anilin- und Sodafabrik bekannt. Bei der Darstellung soll indessen das Natriumbisulfit vor oder gleichzeitig mit dem Schwefelnatrium zur Einwirkung gelangen. Das Product ist denn auch von dem des vorliegenden Patentes gänzlich verschieden. Es ist ein Wollfarbstoff, der aufserordentlich leicht löslich ist in Wasser und aus der alkalischen Lösung durch Säuren nicht gefällt wird.One from α λ c. 4- Dinitronaphthalene, sodium sulphide and sodium bisulphite is already known from patent 92471 of the Badische Anilin- und Sodafabrik. In the illustration, however, the sodium bisulfite should act before or at the same time as the sodium sulphide. The product is completely different from that of the present patent. It is a wool dye that is extremely easily soluble in water and is not precipitated from the alkaline solution by acids.
