KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch das Patent 139099 ist ein Verfahren zur Darstellung eines Schwefelfarbstoffes geschützt, welches darin besteht, daß man den aus dem o-Amido-p-nitro-p^oxydiphenylamin durch Kochen mit Schwefelkohlenstoff erhaltenen Nitrothioharnstoff mit Schwefel und Schwefelnatrium verschmilzt. Es wurde nun gefunden, daß man den gleichen Farbstoff erhält, wenn man den aus dem o-p-Diamido-p^oxydiphenylamin durch Kochen mit Schwefelkohlenstoff erhältlichen Thioharnstoff, welcher naturgemäß von dem nach dem Verfahren des Patentes 139099 verarbeiteten wesentlich verschieden ist, mitThrough the patent 139099 is a method for the preparation of a sulfur dye protected, which consists in the fact that one of the o-amido-p-nitro-p ^ oxydiphenylamine nitrothiourea obtained by boiling with carbon disulfide is fused with sulfur and sodium sulphide. It has now been found that the same dye is obtained if the one from the o-p-diamido-p ^ oxydiphenylamine through Cooking with carbon disulfide available thiourea, which is naturally of the processed according to the method of patent 139099 is substantially different with
J-5 Schwefel und Schwefelnatrium verschmilzt. Es war nun nicht vorherzusehen, daß trotz der Verschiedenheit der Ausgangsmaterialien dennoch identische Farbstoffe entstehen würden; die Identität geht sowohl aus den direkten als auch aus den nachbehandelten Färbungen hervor. Das vorliegende Verfahren unterscheidet sich von dem des Patentes 139099 insofern vorteilhaft, als man bei ersterem die Isolierung des o-Amido-pnitro-p'-oxydiphenylamins in reinem Zustande, die mit Verlusten verknüpft ist und Schwierigkeiten bietet, umgeht. Die Reduktion des Dinitro-p^oxydiphenylamins zur Diamidoverbindung verläuft nämlich glatter als die zum ρ -Nitro- ο- amido -p^oxydiphenylamin. Der Amidoharnstoff ist in Wasser unlöslich, in den gebräuchlichen Lösungsmitteln, wie Alkohol, Benzol usw., ist er schwer löslich; mit Natronlauge bildet er ein leicht lösliches Natriumsalz, mit Salzsäure bezw. Schwefelsäure ein schwer lösliches salzsaures bezw. schwefelsaures Salz; durch die Einwirkung von salpetriger Säure geht er in eine Diazoverbindung über.J-5 sulfur and sodium sulfur merge. It was now impossible to foresee that in spite of this the difference in the starting materials would nevertheless produce identical dyes; the identity is evident from both the direct and the aftertreated dyeings. The present proceedings differs from that of the patent 139099 in that it is advantageous in the former, the isolation of the o-amido-pnitro-p'-oxydiphenylamine in a pure state that is associated with losses and presents difficulties. The reduction of the Dinitro-p ^ oxydiphenylamine to the diamido compound runs more smoothly than that to the ρ -nitro- ο- amido -p ^ oxydiphenylamine. The amidourea is insoluble in water, in the common solvents such as alcohol, benzene, etc., it is sparingly soluble; with Sodium hydroxide he forms a readily soluble sodium salt, with hydrochloric acid or. sulfuric acid a sparingly soluble hydrochloric acid or. sulfuric acid salt; when exposed to nitrous acid, it becomes a diazo compound above.
12 kg des Thioharnstoffe werden mit 60 kg Schwefelnatrium, 40 kg Schwefel 5 Stunden auf 140 bis 145° erhitzt. Nach dem Erkalten wird die Schmelze in Wasser gelöst, mit etwas Natronlauge versetzt und aus der Lösung durch Einleiten von Luft der gereinigte Farbstoff ausgefällt.12 kg of thioureas are mixed with 60 kg of sodium sulfur and 40 kg of sulfur for 5 hours heated to 140 to 145 °. After cooling down the melt is dissolved in water, mixed with a little sodium hydroxide solution and the purified from the solution by introducing air Dye precipitated.
Der Farbstoff färbt Baumwolle direkt in grünlichblauer Nuance, die durch eine Nachbehandlung mit Ferricyankalium oder Wasserstoffsuperoxyd in ein klares lebhaftes Blau übergeht.The dye directly dyes cotton in a greenish-blue shade, which is achieved through an aftertreatment with potassium ferricyanide or hydrogen peroxide turns into a clear, vivid blue.
