PATENTAMT.PATENT OFFICE.
Während ο - ρ - Dinitroderivate des Phenols, Anilins u. s. w. durch Einwirkung von Schwefelnatrium und Schwefel in substantive Baumwollfarbstoffe verwandelt worden sind, liegen über eine diesbezügliche Verwendbarkeit solcher Derivate des Phenols, bei denen sich beide Nitrogruppen in Orthosteilung zum Hydroxyl befinden, keinerlei Erfahrungen vor. In dem D. R. P. 98437 wird zwar angegeben, dafs man anstatt des reinen o-p-Dinitrophenols auch das Gemisch von Dinitrokörpern verwenden kann, wie es beim Nitriren von Phenol entsteht. Hieraus ist indessen nur zu entnehmen, dafs das in diesem Gemisch in geringer Menge enthaltene benachbarte o-o-Dinitrophenol keinen schädlichen Einflufs ausübt. Es läfst sich jedoch daraus nicht ersehen, wie sich das letztere für sich allein verhält, oder wie sich seine Derivate bei Einwirkung von Schwefelnatrium und Schwefel verhalten würden.While ο - ρ - dinitro derivatives of phenol, aniline, etc. by the action of sodium sulphide and sulfur have been converted into substantive cotton dyes are beyond their usefulness in this regard Derivatives of phenol in which both nitro groups are ortho-split to form the hydroxyl do not have any experience. In D. R. P. 98437 it is stated that instead of the pure o-p-dinitrophenol, a mixture of dinitro bodies can also be used can, as it arises from the nitriding of phenol. From this it can only be deduced, however, that the neighboring o-o-dinitrophenol contained in this mixture in small quantities does not harmful influence. It cannot, however, be seen from this how the latter is behaves on its own, or how its derivatives behave when exposed to sodium sulphide and sulfur would behave.
Es hat sich nun gezeigt, dafs gewisse leicht zugängliche Sulfoderivate dieses o-o-Dinitrophenols, welche als gemeinsames Merkmal einen Sulfo- bezw. Sulfonrest in ρ-Stellung zur Hydroxylgruppe enthalten, beim Verschmelzen mit Schwefelalkalien und Schwefel Farbstoffe liefern, welche ungeheizte Baumwolle in tief violettschwarzen Tönen von ganz hervorragender Echtheit anfärben, ohne dafs hierzu eine Nachbehandlung mit Oxydationsmitteln erforderlich wäre.It has now been shown that certain easily accessible sulfoderivatives of this o-o-dinitrophenol, which as a common feature a sulfo or. Sulfone residue in ρ-position to the hydroxyl group when fusing with alkaline sulfur and sulfur Dyes are supplied by unheated cotton in deep purple-black tones of whole dyeing with excellent fastness without the need for an after-treatment with oxidizing agents would be required.
Diese Farbstoffe sind, abgesehen von ihrer Anwendung an und für sich, infolge ihres violettschwarzen Farbtones vorzüglich verwendbar zum Nüanciren bisher dargestellter stark grün- oder blaustichiger Farbstoffe dieser Klasse.These dyes, apart from their application in and of themselves, are due to their violet-black hue excellently usable for the nuanceing of the strongly represented up to now green or bluish dyes in this class.
Als besonders geeignet haben sich erwiesen die o-o-Dinitrophenolsulfosäure, welche entsteht, wenn Phenol - ρ - sulfosäure mit starker Salpetersäure behandelt wird (vergl. das erloschene D. R. P. 27271) und dann das Tetranitrooxysulfobenzid (J. Annaheim, Berichte 11, 1668). Diese Nitroproducte können ersetzt werden durch die entsprechenden Amido- bezw. Nitroamidokörper, welche u. a. durch vollständige bezw. partielle Reduction aus jenen entstehen.The o-o-dinitrophenolsulfonic acid, which is formed when when phenol - ρ - sulfonic acid is treated with strong nitric acid (cf. the extinct D. R. P. 27271) and then the tetranitrooxysulfobenzide (J. Annaheim, Reports 11, 1668). These nitro products can be replaced are resp. by the corresponding amido. Nitroamido bodies, which i.a. through complete respectively partial reduction from those arise.
Zur Erläuterung des Verfahrens dienen folgende Beispiele:The following examples serve to explain the procedure:
In ein geschmolzenes Gemenge von 5OoTheilen krystallisirtem Schwefelnatrium und 1 50 Theilen Schwefel werden bei ioo° bis 1300 unter Rühren 100 Theile Tetranitrooxysulfobenzid eingetragen. Nachdem die durch Schäumen und reichliche Wasserdampfentwicklung sich bemerkbar machende Reaction nachgelassen hat, wird die Temperatur allmählich auf 1400 gesteigert und so lange dabei gehalten, bis die Masse trocken und spröde geworden ist.In a molten mixture of 5OoTheilen crystallized sodium sulphide and 1 50 parts of sulfur 100 parts Tetranitrooxysulfobenzid be entered at ioo ° to 130 0 with stirring. After the reaction, made noticeable by foaming and the abundant development of water vapor, has subsided, the temperature is gradually increased to 140 ° C. and held there until the mass has become dry and brittle.
Die gepulverte Schmelze, welche sich in Wasser mit blauvioletter Farbe löst, kann direct Verwendung finden und färbt Baumwolle in schönen violettschwarzen Tönen an. Behandelt man die so erhaltenen Färbungen mit Kaliumbichromat, so erhält man schöne braune, aufserordentlich waschechte Töne; durch Wasserstoffsuperoxyd bezw. Natriumsuperoxyd tritt keine wesentliche Aenderung der ursprünglichen Nuance ein. Aus der Lösung läfst sich der Farbstoff mittelst KochsalzThe powdered melt, which dissolves in water with a blue-violet color, can direct is used and dyes cotton in beautiful purple-black tones. If the dyeings obtained in this way are treated with potassium dichromate, beautiful ones are obtained brown, extremely washfast tones; by hydrogen peroxide respectively. Sodium peroxide there is no significant change in the original shade. Out of the solution the dye can be removed by means of table salt
oder Chlorammonium ausfällen. Durch Salzsäure wird er in hellbraunen Flocken abgeschieden. Erwärmt man die wässerige Lösung des Farbstoffs mit überschüssigem Schwefelalkali, so tritt äufserst schnell Bildung der Leukoverbindung ein, welche leicht — schon durch den Sauerstoff der Luft — wieder in den Farbstoff übergeht.or precipitate chlorammonium. Hydrochloric acid separates it in light brown flakes. If the aqueous solution of the dye is heated with excess alkali metal, so the formation of the leuco compound occurs extremely quickly, which is easy - yes through the oxygen in the air - passes back into the dye.
In ganz gleicher Weise verfährt man bei Anwendung . der erwähnten Dinitrophenol-psulfosäure. One proceeds in exactly the same way with application. the dinitrophenol-psulfonic acid mentioned.
ι oo Theile ο -Nitro - ο - amidophenol - ρ - sulfosäure werden unter Zusatz von 70 Theilen Wasser mit 32 Theilen calcinirter Soda verrieben und dann mit 140 Theilen Schwefel und 400 Theilen krystallisirtem Schwefelnatrium verschmolzen. Man erhitzt langsam auf 1400 und rührt bei dieser Temperatur, bis die anfangs schäumende Masse fest geworden ist.ι oo parts of ο -nitro - ο - amidophenol - ρ - sulfonic acid are triturated with the addition of 70 parts of water with 32 parts of calcined soda and then fused with 140 parts of sulfur and 400 parts of crystallized sodium sulphide. The mixture is slowly heated to 140 ° C. and stirred at this temperature until the initially foaming mass has solidified.
Der resultirende Farbstoff ist dem nach Beispiel I erhaltenen äufserst ähnlich; er färbt ungeheizte Baumwolle etwas rothstichiger an.The resulting dye is extremely similar to that obtained in Example I; he colors unheated cotton a little more reddish tinged.
Die Färbungen werden beim Nachchromiren braun, durch Wasserstoffsuperoxyd werden sie kaum verändert. Aus der wässerigen violettrothen Lösung werden durch Salzsäure hellgelbe Flocken gefällt. Durch Erhitzen mit Schwefelnatrium tritt schnell Umwandlung in die Leukoverbindung ein.The colorations become brown when they are chrome-plated; they become through hydrogen peroxide barely changed. Light yellow flakes are precipitated from the aqueous violet-red solution with hydrochloric acid. By heating with Sodium sulfur undergoes rapid conversion to the leuco compound.
