Description
Zusatzpatent zum Hauptpatent Nr. 169709. Verfahren zur Herstellung eines indigoiden Farbstoffes. Es wurde gefunden, dass man einen indi- goiden Farbstoff herstellen kann, wenn man 4 . 7 - Dimethylisatin-a-halogenide der Formel
EMI0001.0007
in Gegenwart indifferenter Verdünnungsmittel zunächst mit bromierenden Mitteln behandelt, hierauf mit 1-Ogynaphthalin kondensiert und auf den erhaltenen indigoiden Farbstoff bro- mierende Mittel einwirken lässt.
Der erhaltene Farbstoff löst sich in kon zentrierter Schwefelsäure mit dunkelgrüner Farbe und färbt Baumwolle aus gelblich grüner Küpe in reinen Blautönen; im Baum- wolldruck werden dieselben Farbtöne erhalten. Der Farbstoff lässt sich nach den üblichen Verfahren in Leukoestersalze überführen.
Die Behandlung der 4.7-Dimethylisatin- a-halogenide (a-chlorid oder -a-bromid) in Gegenwart indifferenter Verdünnungsmittel, wie zum Beispiel Benzol, Chlorbenzol, Nitro- benzol, Tetrachloräthan oder Chloroform, mit bromierenden Mitteln kann in Gegenwart oder Abwesenheit von Halogenüberträgern, wie zum Beispiel Jod, Antimonpentachlorid oder Eisen und dessen Salzen, erfolgen.
Die auf die Bromierung der 4.7-Dimethyl- isatin-a-halogenide folgende Kondensation mit 1- Ogynaphthalin kann nach bekannten Me thoden in Gegenwart indifferenter Verdün nungsmittel, wie zum Beispiel Benzol, Chlor benzol, Nitrobenzol, Tetrachloräthan oder Chloroform, durchgeführt werden.
Der erhaltene indigoide Farbstoff kann in analoger Weise, wie es bei der Bromierung der 4.7-Dimethylisatin-a-halogenide beschrie ben worden ist, mit bromierenden Mitteln behandelt werden.
Eine vorteilhafte Ausführungsform des vorliegenden Verfahrens besteht darin, dass als Ausgangsstoffe Reaktionsgemische ver wendet werden, wie sie durch Einwirkung von Phosphorhalogeniden, wie zum Beispiel Phosphorpentachlorid oder Phosphorpenta- bromid, auf das 4.7-Dimethylisatin in Gegen wart indifferenter Verdünnungsmittel erhält lich sind:
Von besonderem Wert ist diejenige Aus führungsform des vorliegenden Verfahrens, bei der' sowohl die Herstellung der 4.7-Di- methylisatin-a-halogenide bezw. die Behand lung dieser Isatin-a-halogenide mit bromfie- renden Mitteln und die Kondensation mit 1- Oxynaphthalin, als auch die Einwirkung bromfierender Mittel auf den erhaltenen indi- goiden Farbstoff, in Gegenwart des selben indifferenten Verdünnungsmittels erfolgt.
<I>Beispiel:</I> 17,5 Teile 4 . 7 - Dimethylisatin werden durch zweistündiges Erwärmen mit 22 Teilen Phosphorpentachlorid und 600 Teilen Benzol auf 70-7"e in das 4.7-Dimethylisatin-a- chlorid übergeführt. Nach dem Abkühlen auf etwa 5 werden 17,2 Teile Brom, verdünnt mit etwas Benzol, langsam zugegeben und zur Vervollständigung der Bromierung inner halb 2 Stunden auf 40-45" erwärmt.
Das so erhaltene Reaktionsgemisch lässt man nach dem Abfiltrieren von Verunreinigungen zu einer Lösung von 14,4 Teilen 1-Oxynaphtha- lin in 300 Teilen Benzol bei 45 fliessen und kühlt nach kurzem Rühren auf 5 ab. Nach Zugabe von 17,2 Teilen Brom, verdünnt mit etwas Benzol, und Beendigung der Bromierung durch einstündiges Erwärmen auf 45 - 50 wird filtriert, mit Benzol, sowie mit Alkohol gewaschen und getrocknet.
Additional patent to main patent no. 169709. Process for the production of an indigoid dye. It has been found that an indigoid dye can be produced if one 4. 7 - Dimethylisatin-a-halides of the formula
EMI0001.0007
first treated with brominating agents in the presence of indifferent diluents, then condensed with 1-ogynaphthalene and left brominating agents to act on the indigoid dye obtained.
The dye obtained dissolves in concentrated sulfuric acid with a dark green color and dyes cotton from a yellowish green vat in pure blue tones; the same color tones are obtained in cotton printing. The dye can be converted into leuco ester salts by the usual methods.
The treatment of the 4,7-dimethylisatin a-halide (a-chloride or a-bromide) in the presence of inert diluents, such as benzene, chlorobenzene, nitrobenzene, tetrachloroethane or chloroform, with brominating agents can be carried out in the presence or absence of halogen carriers , such as iodine, antimony pentachloride or iron and its salts.
The condensation with 1-ogynaphthalene following the bromination of the 4,7-dimethyl-isatin-a-halides can be carried out according to known methods in the presence of inert diluents such as benzene, chlorobenzene, nitrobenzene, tetrachloroethane or chloroform.
The indigoid dye obtained can be treated with brominating agents in a manner analogous to that described for the bromination of 4,7-dimethylisatin-a-halides.
An advantageous embodiment of the present process consists in that the starting materials used are reaction mixtures such as are obtainable by the action of phosphorus halides, such as phosphorus pentachloride or phosphorus pentabromide, on the 4,7-dimethylisatin in the presence of inert diluents:
Of particular value is that embodiment of the present process in which 'both the preparation of the 4,7-dimethylisatin-a-halides respectively. the treatment of these isatin a-halides with brominating agents and the condensation with 1-oxynaphthalene, as well as the action of brominating agents on the indigoid dye obtained, takes place in the presence of the same inert diluent.
<I> Example: </I> 17.5 parts 4. 7 - Dimethylisatin is converted into 4.7-dimethylisatin a-chloride by heating for two hours with 22 parts of phosphorus pentachloride and 600 parts of benzene to 70-7 "e. After cooling to about 5, 17.2 parts of bromine, diluted with a little benzene, are added. added slowly and heated to 40-45 "within 2 hours to complete the bromination.
The reaction mixture obtained in this way, after impurities have been filtered off, is allowed to flow to a solution of 14.4 parts of 1-oxynaphthalene in 300 parts of benzene at 45 and, after brief stirring, cooled to 5. After adding 17.2 parts of bromine, diluted with a little benzene, and termination of the bromination by heating to 45-50 for one hour, the mixture is filtered, washed with benzene and with alcohol and dried.
