Zusatz zum Patente 197165 vom 8. November 1905.Addendum to patent 197165 of November 8, 1905.
Patentiert im Deutschen Reiche vom 6. Dezember 1905 ab. Längste Dauer: 7. November 1920.Patented in the German Empire on December 6, 1905. Longest duration: November 7, 1920.
Es wurde gefunden, daß man den in der Patentschrift 197165 beschriebenen schwarzen Farbstoff aus p-Nitroso-o-cresol auch durch gleichzeitiges Kochen dieser Verbindung mit einer wäßrigen Lösung von Schwefelnatrium und Schwefel erhalten kann, wodurch nicht allein die Herstellung vereinfacht, sondern auch der Vorteil eines sicheren Arbeitens erreicht wird. Ferner können auch noch auf diese Weise mit Leichtigkeit die verschiedensten schwarzen Nuancen durch Änderung der Schwefel- und Alkaliquantitäten erhalten werden. It has been found that the black described in Patent 197165 Dye from p-nitroso-o-cresol also by cooking this compound at the same time an aqueous solution of sodium sulfur and sulfur can be obtained, whereby not only simplifies the production, but also achieves the advantage of safe working will. Furthermore, in this way, the most diverse black nuances can be obtained by changing the sulfur and alkali quantities.
14 Teile ρ - Nitroso - ό - cresol werden mit 18 Teilen kristallisiertem Schwefelnatrium, 5 Teilen Schwefel und etwa 50 Teilen kaltem Wasser gemischt und dann langsam zum Kochen erhitzt. Es entsteht zuerst ein braunes Produkt durch die teilweise Reduktion des Nitroso-o-cresols, dann geht die Färbung nach einiger Zeit in Violett und schließlich in Grünblau über. Die Reaktion dauert ungefähr 24 Stunden. Während des Kochens wird das verdampfende Wasser durch geeignete Vorrichtungen in den Kochapparat zurückgeführt, oder man läßt einen kleinen Wasserstrahl, dessen Menge dem verdampfenden Wasser ungefähr gleichkommt, in den Kochapparat einfließen. Die Lösung kann nun entweder direkt zum Färben benutzt oder zur Trockne verdampft werden, oder man kann den Farbstoff durch Säuren ausfällen.14 parts ρ - nitroso - ό - cresol are with 18 parts of crystallized sodium sulfur, 5 parts of sulfur and about 50 parts of cold Water mixed and then slowly heated to a boil. First a brown one emerges Product due to the partial reduction of the nitroso-o-cresol, then the color follows for a while in purple and finally in green-blue. The reaction takes approximately 24 hours. During the boiling, the evaporating water is through suitable devices returned to the cooking apparatus, or a small jet of water is allowed, the amount of which corresponds to the evaporating water approximately to flow into the cooking apparatus. The solution can now either be used directly for dyeing or evaporated to dryness or the dye can be precipitated using acids.
Vorstehendes Beispiel ergibt ein Schwarz von blau-violetter Nuance. Ein Schwarz von bläulich-grüner Nuance, das besonders für mercerisierte Baumwolle geeignet ist, erhält man z. B. durch Kochen von 14 Teilen Nitrosoo-cresol, 30 Teilen kristallisiertem Schwefelnatrium und 12 Teilen Schwefel unter Wasserzusatz. The above example results in a black with a blue-violet shade. A black from bluish-green shade, which is particularly suitable for mercerized cotton one z. B. by boiling 14 parts of nitroso-cresol, 30 parts of crystallized sodium sulfur and 12 parts of sulfur with the addition of water.
Ein Teil des Schwefelnatriums kann durch kaustische Alkalien oder Alkalikarbonate ersetzt werden, da sich anscheinend zuerst p-Nitroso-o-cresolnatrium bildet. Die Natriumverbindung kann man z. B. durch Anwendung einer Lösung von etwa 4 Teilen Natriumhydroxyd auf 14 Teilen Nitrosocresol bilden, wodurch 12 Teile kristallisiertes Schwefelnatrium erspart werden. Man setzt dann Schwefelnatrium und Schwefel (oder auch die schon vorher gebildeten Polysulfide) erst zu, wenn das Nitroso-o-cresol in der Natronlauge gelöst ist.A part of the sulphurous sodium can be replaced by caustic alkalis or alkali carbonates as p-nitroso-o-cresol sodium appears to be formed first. The sodium compound you can z. B. by applying a solution of about 4 parts of sodium hydroxide to 14 parts of nitrosocresol, saving 12 parts of crystallized sodium sulphide. Then you bet Sulfur sodium and sulfur (or the previously formed polysulfides) only when the nitroso-o-cresol is dissolved in the sodium hydroxide solution.
