Description

Verfahren zur Darstellung von grünen Küpenfarbstoffen der Benzanthronreihe. Zusatz zum Patent 436 828. In dem Patent 436 828 ist gezeigt, daß man neue Farbstoffe erhält, wenn man die durch Alkylierung von Oxydationsprodukten des Dibenzanthrons und seiner Derivate oder deren Umwandlungsprodukte erhältlichen Farbstoffe halogeniert.Process for the preparation of green vat dyes of the benzanthrone series. Addendum to Patent 436,828. Patent 436,828 shows that one can produce new dyes obtained when the alkylation of oxidation products of dibenzanthrone and its derivatives or their conversion products are halogenated.

Es wurde nun weiter gefunden, daß ähnliche Farbstoffe erhalten werden, wenn man die in dem Patent 28o 7io beschriebenen grünen Küpenfarbstoffe mit alkylierenden Mitteln behandelt.It has now been found that similar dyes are obtained if one of the green vat dyes described in the patent 28o 7io with alkylating Means treated.

Beispiel. 3 Teile des Farbstoffs des Beispiels i des Patents 28o 7io werden mit i 5o Teilen Nitrobenzol, 3 Teilen calc. Soda und 3 Teilen Toluolsulfosäuremethylester drei Stunden zum Sieden erhitzt, sodann werden nochmals 3 Teile calc. Soda und 3 Teile Toluoisulfosäuremethylester zugesetzt und wieder drei Stunden gekocht und der Zusatz des Methylierungsmittels so lange fortgesetzt, bis eine herausgenommene Probe des Farbstoffes beim Färben auf Baumwolle eine grüne Färbung gibt, die beim Betupfen mit Säure nicht mehr stark nach blau umschlägt. Der bei gewöhnlicher Temperatur praktisch unlösliche Farbstoff wird in der üblichen Weise aufgearbeitet. Er ist bromhaltig und färbt Baumwolle aus der Küpe in leuchtend grünen Tönen an. In 23prozentigem Oleum löst er sich mit rötlichbrauner Farbe.Example. 3 parts of the dye of example i of patent 28o 7io are with i 50 parts of nitrobenzene, 3 parts of calc. Soda and 3 parts of methyl toluenesulfate Heated to the boil for three hours, then another 3 parts of calc. Soda and 3 Parts of toluoisulfonic acid methyl ester added and boiled again for three hours and the addition of the methylating agent continued until one removed A sample of the dye gives a green coloration when dyeing on cotton Dabbing with acid no longer turns blue. The one at ordinary temperature practically insoluble dye is worked up in the usual way. He is contains bromine and stains cotton from the vat in bright green tones. In 23 percent It dissolves oleum with a reddish-brown color.
