Description

Verfahren zur Darstellung von festen, beständigen wasserlöslichen Abkömmlingen von Küpenfarbstoffen. Zusatz zum Patent 424981. Nach dem Verfahren des Hauptpatents 4=498I werden wasserlösliche esterartige Abkämmlinge von Küpenfarbstoffen hergestellt durch Behandlung der Leukoverbindungen der Küpenfarbstoffe mit Chlorsulfonsäure bei Gegenwart einer tertiären Base mit oder ohne Verwendung eines indifferenten Verdünnungsmittels.Process for the preparation of solid, permanent water-soluble Derived from vat dyes. Addendum to Patent 424981. According to the procedure of the main patent 4 = 498I are water-soluble ester-like combs of vat dyes produced by treating the leuco compounds of the vat dyes with chlorosulfonic acid in the presence of a tertiary base with or without the use of an indifferent one Diluent.

Es wurde nun gefunden, daß in diesem Verfahren die Chlorsulfonsäure durch Salze dieser Säure, z. B. durch Natriumchlorsulfonat, ersetzt werdest kann. Diese Abänderung erlaubt, die zu verwendende Menge an tertiärer Base herabzusetzen.It has now been found that the chlorosulfonic acid in this process by salts of this acid, e.g. B. by sodium chlorosulfonate, can be replaced. This modification allows the amount of tertiary base to be used to be reduced.

Beispiel. Unter gutem Rühren werden 26 Teile Leukoindigo bei gewöhnlicher Temperatur und unter Kohlensäureabschluß in ein Gemisch von I2o Teilen Chlorbenzol, 36 Teilen Dimethylanilin und 4o Teilen Na S03 Cl, 87 Prozent, eingetragen. Es wird einige Zeit kalt gerührt und dann die Reaktionsmasse langsam auf 5o bis 6o° C gebracht. Man setzt das Rühren bis zum Schlusse der Reaktion fort.Example. With good stirring, 26 parts of leuco indigo become more common Temperature and with exclusion of carbon dioxide in a mixture of 12o parts of chlorobenzene, 36 parts of dimethylaniline and 40 parts of Na SO3 Cl, 87 percent, entered. It will Stirred cold for some time and then slowly brought the reaction mass to 50 to 60 ° C. Stirring is continued until the reaction is complete.

Die Aufarbeitung ist dieselbe wie im Beispiel 2 des Hauptpatents.The work-up is the same as in Example 2 of the main patent.
