Description

Verfahren zur Darstellung von neuen Küpenfarbstoffen Es wurde gefunden, daß man neue, wertvolle marineblaue Küpenfarbstoffe erhält, wenn man auf Dibenzanthron, Isodibenzanthron oder deren Derivate Chlorschwefel in Gegenwart eines kondensierend wirkenden Metallhalogenids einwirken läßt. Geeignete Kondensationsmittel sind z. B. Aluminiumchlorid, Eisenchlorid usw. Die neuen Produkte enthalten Chlor und Schwefel und können auch als Zwischenprodukte zur Darstellung neuer Körper Verwendung finden. Beispiel i io Teile reines Dibenzanthron werden mit 4.o Teilen Chlorschwefel und q. Teilen Aluminiumchlorid etwa i bis 2 Stunden lang bei i000 C gerührt. Man läßt erkalten, verdünnt mit Benzol, saugt ab, wäscht mit Benzol, Alkohol und Wasser nach und trocknet. Der neue Farbstoff ist ein dunkelblaues Pulver, das sich in Schwefelsäure mit rotvioletter Farbe löst. Er färbt Baumwolle aus blauer Küpe in kräftigen blauen Tönen.Process for the preparation of new vat dyes It was found that you get new, valuable navy blue vat dyes when you go on dibenzanthrone, Isodibenzanthrone or its derivatives chlorosulfur in the presence of a condensing acting metal halide can act. Suitable condensing agents are, for. B. aluminum chloride, ferric chloride, etc. The new products contain chlorine and sulfur and can also be used as intermediate products to create new bodies. Example io parts of pure dibenzanthrone are mixed with 4.o parts of chlorosulfur and q. Parts of aluminum chloride are stirred at 1000 ° C. for about 1 to 2 hours. One lets cool, dilute with benzene, suction off, wash with benzene, alcohol and water and dries. The new dye is a dark blue powder that turns into sulfuric acid dissolves with red-violet paint. He dyes cotton from a blue vat in strong blue Tones.

Ein ähnliches Produkt erhält man, wenn man von Trichlordibenzanthron, dargestellt durch Chlorieren von Dibenzanthron in Trichlarbenzol, ausgeht.A similar product is obtained if one of trichlorodibenzanthrone, represented by chlorinating dibenzanthrone in trichlarbenzene.

Beispiel e io Teile Isodibenzanthron werden mit 6o Teilen Chlorschwefel und io Teilen Aluminiumchlorid i Stunde lang auf ioo° C erhitzt. Sodann wird wie im Beispiel i verfahren. Der neue Farbstoff färbt Baumwolle aus grüner Küpe in blauen Tönen.Example e 10 parts of isodibenzanthrone are mixed with 60 parts of chlorosulphur and 10 parts of aluminum chloride heated to 100 ° C. for one hour. Then how Proceed in example i. The new dye dyes cotton from a green vat in blue Tones.

Ein ähnliches Produkt erhält man, wenn man das nach dem Patent 217 570 hergestellte Dichlorisodibenzanthron in analoger Weise behandelt.A similar product is obtained if one uses the patent 217 570 produced dichloroisodibenzanthrone treated in an analogous manner.
