Verfahren zur Herstellung von Küpenfarbstoffen.Process for the production of vat dyes.
Patentiert im Deutschen Reiche vom 3. Juni 1906 ab.Patented in the German Empire on June 3, 1906.
Durch das Patent 202696 ist ein Verfahren zur Darstellung von Substitutionsprodukten des 3-Oxy(i)thionaphtens geschützt. Es wurde nun gefunden, daß die Substitutionsprodukte durch Oxydation leicht in sehr wertvolle Farbstoffe übergehen, welche Substitutionsprodukte des unter dem Namen Thioindigorot B bekannten Farbstoffes vorstellen.Patent 202696 describes a method for the preparation of substitution products protected from 3-oxy (i) thionaphthene. It has now been found that the substitution products by oxidation easily pass into very valuable dyes, which are substitution products of the dye known under the name Thioindigo Red B.
Zum Zwecke ihrer Gewinnung ist es lediglieh erforderlich, in dem Verfahren des Patentes 194237 das dort verwendete 3-Oxy(i)-thionaphten durch äquivalente Mengen seiner Substitutionsprodukte zu ersetzen. Die erhaltenen. Farbstoffe stehen in ihren gesamten Eigenschaften in naher Verwandtschaft zum Thioindigorot B.For the purpose of their extraction it is single required, in the process of patent 194237 the 3-oxy (i) -thionaphthene used there to be replaced by equivalent amounts of its substitution products. The received. All of their properties are closely related to thioindigo red B.
i8,5 kg 5-Chlor-3-oxy(i)thionaphten werden in Wasser unter Zusatz der erforderlichen Menge Alkali so lange mit einer wässerigen Lösung von gelbem Blutlaugensalz versetzt, als noch Ausscheidung von Farbstoff erfolgt. Dieser wird dann nitriert und ausgewaschen. Er erzeugt in der Küpe auf Baumwolle blaurote Nuancen. An Stelle von Ferricyankalium können mit gleichem Erfolge auch andere : Oxydationsmittel benutzt werden.8.5 kg of 5-chloro-3-oxy (i) thionaphtene will be used in water with the addition of the required amount of alkali for so long with an aqueous one A solution of yellow blood liquor salt was added while the dye was still being excreted. This is then nitrided and washed out. In the vat it produces blue-red on cotton Nuances. Instead of potassium ferricyanide, others can also: Oxidizing agents can be used.
Ersetzt man in obigem Beispiel das 5-Chlor-3-oxy(i)thionaphten durch andere Substitutionsprodukte des 3-Oxy(i)thionaphtens, so wird dadurch an dem Verfahren -' nichts geändert. Der Farbstoff aus 6-Nitro-3-oxy(i)thionaphten erzeugt auf Baumwolle braunrote Nuancen, jener aus dem 5-Methyl-3-oxy(i)thionaphten rotstichig violette Farbtöne.If the 5-chloro-3-oxy (i) thionaphthene is replaced in the above example by other substitution products of 3-oxy (i) thionaphthene, so becomes thereby in the procedure - 'nothing changed. The dye from 6-nitro-3-oxy (i) thionaphtene produces brownish-red nuances on cotton, those from 5-methyl-3-oxy (i) thionaphthene reddish purple hues.
