Description
Zusatzpatent zum Hauptpatent Nr. 290293. Verfahren zur Herstellung eines Farbstoffzwischenproduktes der Anthrachinonreihe. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Farbstoff zwischenproduktes der Anthrachinonreihe, wel ches darin besteht, dass man 1,4-Di-(2',6'- dimethyjphenyjamino) - 6,7 - dichloranthrachi- non durch Behandeln mit Chlorsulfonsäure in 7 ,4-Di-(2',6'-dimethylphenylamino)-6,
7-dichlor- anthrachinon-disulfonsäurechlorid überführt.
Es ist bekannt, dass Arylaminoanthraehi- none durch Einwirkung von Chlorsulfonsäure oft schon bei Zimmertemperatur Coeramido- ninringschluss erleiden, wobei ihre Farbe stark erhöht wird. Ferner kennt man zahl reiche Verfahren in der Anthrachinonreihe, welche die Chlorsulfonsäure zur Sulfonierung verwenden und zu wasserlöslichen Verbin dungen führen.
Das nach dem neuen Ver fahren erhältliche Produkt ist dagegen in kaltem Wasser nicht löslich und zeigt gegen über dem Ausgangsstoff keine auf Coeramido- ninringschluss weisende Farberhöhung. Es ent hält pro Molekül 2 Atome Schwefel und 2 Atome austauschbaren Chlors und ist daher offenbar ein Sulfonsäurechlorid. Es soll zur Darstellung von neuen Farbstoffen verwendet werden.
Die Ausführung des Verfahrens erfolgt zweckmässig derart, dass man unter Rühren bei einer Temperatur von -10 bis +100 C den Ausgangsstoff in Chlorsulfonsäure oder in ein Gemisch aus Chlorsulfonsäure und Schwefelsäuremonohydrat bzw. rauchender Schwefelsäure einträgt und die Masse inner halb der gleichen Temperaturgrenze so lange weiterrührt, bis eine Probe davon sich in heisser verdünnter Alkalihydroxydlösung löst, in kaltem Wasser dagegen unlöslich ist.
Man giesst dann die Reaktionsmasse auf Eis oder auf eine Mischung von Eis und Wasser oder Salzwasser, filtriert den gebildeten Nieder schlag und wäscht ihn mit Wasser bzw. Salz wasser neutral.
Das Produkt kann als feuchte Paste wei terverarbeitet werden, es kann aber auch durch vorsichtiges Trocknen, am besten im Vakuum bei niedriger, z. B. Zimmertempera tur; entwässert werden.
In den Beispielen bedeuten die Teile Ge wichtsteile, und die Temperaturen sind in Celsiusgraden angegeben.
<I>Beispiel 1:</I> In 220 Teile Chlorsulfonsäure von 0 trägt man 25,8 Teile 1,4-Di-(2',6'-dimethylphenyl- amino)-6,7-dichloranthrachinon innerhalb von 45 Minuten ein und rührt das Gemisch an schliessend 4 Stunden lang bei 35 bis 40 . Eine Probe löst sich nun beim Kochen in 20/aiger Natriumhydroxydlösung mit rotstickig blauer Farbe, ist dagegen in kaltem Wasser unlöslich; diese Fällung lässt sich mit Essigsäureäthyl- ester ausziehen. Man giesst die Masse auf 1400 Teile Eis, filtriert die ausgeschiedene Verbindung und wäscht sie neutral.
Das neue Farbstoffzwischenprodukt ist ein dunkelblaues Pulver, das sich in Benzol mit rotstickig blauer und in konzentrierter Schwefelsäure mit blauer Farbe löst. <I>Beispiel 2:</I> Ersetzt man im Beispiel 1 die 220 Teile Chlorsulfonsäure durch eine Mischung aus 110 Teilen Chlorsulfonsäure und 50 Teilen Schwefelsäuremonohydrat und arbeitet eben falls bei 35 bis 40 , so erhält man dieselbe Verbindung.
Additional patent to main patent No. 290293. Process for the preparation of a dye intermediate of the anthraquinone series. The present patent is a process for the preparation of a dye intermediate product of the anthraquinone series, wel Ches consists in that 1,4-di- (2 ', 6'-dimethyjphenyjamino) - 6,7 - dichloroanthraquinone by treatment with chlorosulfonic acid in 7, 4-di- (2 ', 6'-dimethylphenylamino) -6,
7-dichloro-anthraquinone disulfonic acid chloride transferred.
It is known that arylaminoanthraquinones often undergo coeramidino ring closure at room temperature as a result of the action of chlorosulfonic acid, whereby their color is greatly increased. Furthermore, there are numerous processes in the anthraquinone series that use chlorosulfonic acid for sulfonation and lead to water-soluble compounds.
The product obtainable according to the new process, on the other hand, is not soluble in cold water and does not show any increase in color compared to the starting material indicating coeramidino ring closure. It contains 2 atoms of sulfur and 2 atoms of exchangeable chlorine per molecule and is therefore apparently a sulfonic acid chloride. It should be used to represent new dyes.
The process is conveniently carried out in such a way that the starting material is introduced into chlorosulfonic acid or a mixture of chlorosulfonic acid and sulfuric acid monohydrate or fuming sulfuric acid while stirring at a temperature of -10 to +100 C and the mixture is kept stirring within the same temperature limit until a sample of it dissolves in hot, dilute alkali metal hydroxide solution, but is insoluble in cold water.
The reaction mass is then poured onto ice or onto a mixture of ice and water or salt water, the precipitate formed is filtered off and washed neutral with water or salt water.
The product can be further processed as a moist paste, but it can also be dried carefully, preferably in a vacuum at a low temperature, e.g. B. room temperature; be drained.
In the examples, the parts are parts by weight and the temperatures are given in degrees Celsius.
Example 1: 25.8 parts of 1,4-di- (2 ', 6'-dimethylphenyl-amino) -6,7-dichloroanthraquinone are introduced into 220 parts of chlorosulfonic acid of 0 in the course of 45 minutes and then stir the mixture for 4 hours at 35 to 40. A sample dissolves when boiled in 20% sodium hydroxide solution with a red-sticky blue color, but is insoluble in cold water; this precipitate can be extracted with ethyl acetate. The mass is poured onto 1400 parts of ice, the compound which has separated out is filtered off and washed neutral.
The new intermediate dye product is a dark blue powder that dissolves in benzene with a reddish blue color and in concentrated sulfuric acid with a blue color. <I> Example 2: </I> If the 220 parts of chlorosulphonic acid in Example 1 are replaced by a mixture of 110 parts of chlorosulphonic acid and 50 parts of sulfuric acid monohydrate and if the temperature is 35 to 40, the same compound is obtained.
