Patentirt im Deutschen Reiche vom 4, September igol ab.Patented in the German Empire from September 4th igol.
Durch Behandeln von Benzylsulfosäure mit Salpeterschwefelsäure in der Wärme erhält man die von Mohr (Annalen 221, 225) beschriebene Dinitrobenzylsulfosäure.By treating benzylsulfonic acid with nitric sulfuric acid in heat, one obtains the dinitrobenzyl sulfonic acid described by Mohr (Annalen 221, 225).
Es hat sich nun gezeigt, dafs dieses Product durch Erhitzen mit Schwefel und Schwefelalkali bezw. Alkalipolysulfiden, am zweckmäfsigsten bei Temperaturen zwischen 200 bis 2500, in einen neuen Schwefelfarbstoff umgewandelt wird, welcher Baumwolle in alkalischem Bade in gelbbrauner, licht- und waschechter Nuance anfärbt.It has now been shown that this product can be obtained by heating with sulfur and alkali sulfur, respectively. Alkali polysulphides, most expediently at temperatures between 200 and 250 0 , is converted into a new sulfur dye which dyes cotton in an alkaline bath in a yellow-brown, lightfast and washfast shade.
In eine Lösung aus 1 Th. Schwefel, 3 Th. Schwefelnatrium (kryst.) und 2 Th. Wasser trägt man bei 60 bis 80 ° allmählich unter Rühren 1 Th. dinitrobenzylsulfosaures Natrium ein, erhitzt dann auf 150 bis 2000 bis zum Dickwerden der Schmelze, steigert die Temperatur bis 240 bis 2500 und hält hierbei so lange, bis die Masse völlig trocken geworden ist. Das so erhaltene Reactionsproduct stellt' eine schwärzliche, brüchige Masse dar, welche sich in Wasser mit gelblich brauner Farbe auflöst; der Farbstoff läfst sich aus dieser Lösung durch Kochsalz oder Säuren ausfällen. Concentrirte Schwefelsäure nimmt ihn mit brauner Farbe auf. Die mit dem Farbstoff erzielten Färbungen lassen sich den üblichen Nachbehandlungsmethoden unterwerfen, doch finden hierbei keine wesentlichen Aenderungen, weder in Bezug auf Nuance noch hinsichtlich der Echtheitseigenschaften, statt. Der Farbstoff besitzt aufserdem die bemerkenswerthe Eigenschaft, sich auf der Faser diazotiren zu lassen und dann mit Phenolen und Aminen zu kuppeln.(Kryst.) In a solution of 1 Th. Sulfur, 3 parts. Sulphide and 2 Th. Of water, contributes 60 to 80 ° gradually with stirring for 1 Th. Dinitrobenzylsulfosaures sodium, then heated to 150 to 200 0 to the curdling of Melt, increases the temperature to 240 to 250 0 and holds it until the mass has become completely dry. The reaction product thus obtained is a blackish, brittle mass which dissolves in water with a yellowish brown color; the dye can be precipitated from this solution using common salt or acids. Concentrated sulfuric acid absorbs it with a brown color. The colorations achieved with the dye can be subjected to the customary aftertreatment methods, but there are no significant changes, either in terms of shade or in terms of the fastness properties. The dye also has the remarkable property of being diazotized on the fiber and then coupling with phenols and amines.
