Zusatz zum Patente 131725 vom 4. September igoi.Addition to the patent 131725 from September 4th igoi.
Patentirt im Deutschen Reiche vom 17. Dezember igoi ab. Längste Dauer: 3. September 1916.Patented igoi in the German Empire on December 17th. Longest duration: September 3, 1916.
In der Patentschrift 131725 ist ein gelbbrauner Schwefelfarbstoff beschrieben worden, welcher durch Behandlung von Dinitrobenzylsulfosä'ure mit Schwefel und Schwefelalkalien erhalten wird.In the patent specification 131725 a yellow-brown sulfur dye has been described, which by treating dinitrobenzylsulfonic acid with sulfur and alkaline sulfur is obtained.
Es hat sich nun gezeigt, dafs in diesem Verfahren die Dinitroverbindung durch das p-Mononitroderivat bezw. durch das rohe Mononitroproduct, wie es aus Benzylsulfosäure durch Nitriren erhalten wird (s. Annalen 221, S. 216), ersetzt werden kann. Hierbei entsteht ein substantiver Schwefelfarbstoff von im Allgemeinen ähnlichen Eigenschaften wie jener des Haupt-Patentes, der aber von diesem durch eine gelbere Nuance unterschieden ist.It has now been shown that in this process the dinitro compound is replaced by the p-Mononitro derivative respectively. by the crude mononitroproduct, as it is from benzylsulfonic acid is obtained by nitriding (see Annalen 221, p. 216), can be replaced. This creates a substantive sulfur dye of generally similar properties to those of des Main patent, which is differentiated from this one by a more yellow shade.
In eine Lösung aus 1 Theil Schwefel, 3 Theilen Schwefelnatrium (kryst.) und 2 Theilen Wasser wird unter Rühren bei ca. 60 bis 8o° ι Theil mononitrobenzylsulfosaures Natrium eingetragen und das Gemenge so lange bei 150 bis 2oo° gehalten, bis die Schmelze fast hart geworden ist. Nach dem Erkalten wird die Schmelze zerkleinert und noch einige Zeit auf 220 bis 2400 erhitzt. Sie stellt alsdann eine bräunliche Masse dar, welche sich in Wasser mit bräunlichgelber Farbe auflöst und direct zum Färben Verwendung finden kann. Mineralsäuren oder Kochsalz fällen den Farbkörper aus seinen Lösungen in Form von gelblichen Flocken aus. Der Farbstoff färbt ungeheizte Baumwolle direct bräunlichgelb an, und es zeichnen sich die damit erzielten Färbungen besonders durch ihre Wasch- und Chlorechtheit aus. Der Farbstoff läfst sich auf der Faser den üblichen Nachbehandlungsmethoden unterwerfen, aufserdem besitzt er wie derjenige des Haupt-Patentes die Eigenschaft, sich auf der Faser diazotiren und dann mit Phenolen und Aminen kuppeln zu lassen.Sodium mononitrobenzylsulfonic acid is introduced into a solution of 1 part sulfur, 3 parts sulfur sodium (crystalline) and 2 parts water, with stirring at about 60 to 80 °, and the mixture is kept at 150 to 200 ° until it almost melts has become hard. After cooling the melt is comminuted and heated for some time at 220 to 240 0th It then represents a brownish mass, which dissolves in water with a brownish-yellow color and can be used directly for dyeing. Mineral acids or common salt precipitate the color body from its solutions in the form of yellowish flakes. The dye stains unheated cotton directly to a brownish yellow, and the dyeings obtained with it are particularly notable for their fastness to washing and chlorine. The dye can be subjected to the usual post-treatment methods on the fiber, and, like that of the main patent, it has the property of being diazotized on the fiber and then being coupled with phenols and amines.
