Description
Verfahren zur Herstellung eines Diazosalzpräparates für Färberei und Druckerei. -Es wurde gefunden, dass man ein geit haltbares Diazosalzpräparat für Färberei und Druckerei erhält, wenn man die wie üblich hergestellte mineralsaure Diazosalz- lösung von o-Aminodiphenyläther der For mel:
EMI0001.0008
mit einem 1.5-naphtalindistilfosauren tallsalz umsetzt.
Das so erhaltene neutrale 1. 5-NaphtaIin- disulfonat des diazotierten o-Aminodiphenyl- äthers von z. B. 40 % Gehalt an Amino- phenylätherbase bildet ein bräunliches, gut haltbares, lösliches, unmittelbar zum Aus färben grundierter Baumwolle geeignetes Di- azosalzprä.pa.rat, das zweckmässig mit geeig neten, die Ausfärbungen, die Löslichkeit und die Haltbarkeit günstig beeinflussenden Zu sätzen und Färbereihilfsmitteln, wie zum Beispiel Aluminiumsulfat oder Alaun,
aryl- sulfosauren Metallsalzen und dergleichen, noch auf einen handelsüblichen Diazogehalt eingestellt wird. Beispiel: Eine aus 185 Teilen ortlio-Aminodiplien 5-1 äther in üblicher Weise hergestellte konzen trierte Lösung des Diazochlörids wird mit 190 Teilen 1.5-naphtalindisulfosaurem Na trium, Mol.-Gewicht 332, bis zur völligen Umsetzung verrührt;
dann wird abfiltriert und das Diazosalz bei mässiger Temperatur getrocknet und unter Umständen durch Ver mischen mit geeigneten Färbereihilfsstoffen in handelsfertige Form gebracht. Diese Zu sätze können auch dem noch feuchten Diazo- salz zugemischt werden.
Process for the production of a diazo salt preparation for dyeing and printing. -It has been found that a diazo salt preparation that can be kept stable for dyeing and printing is obtained if the mineral acid diazo salt solution of o-aminodiphenyl ether of the formula, prepared as usual, is obtained:
EMI0001.0008
with a 1.5-naphtalindistilfosauren metal salt.
The neutral 1.5-naphthalenedisulfonate thus obtained of the diazotized o-aminodiphenyl ether of z. B. 40% aminophenyl ether base content forms a brownish, long-lasting, soluble, diazo salt preparation which is suitable for dyeing primed cotton and which is expediently mixed with suitable additives which have a beneficial effect on coloration, solubility and durability sets and dyeing auxiliaries, such as aluminum sulfate or alum,
aryl sulfonic acid metal salts and the like, is still adjusted to a commercial Diazo content. Example: A concentrated solution of the diazochloride prepared in the usual way from 185 parts of ortlio-aminodiplien 5-1 ether is stirred with 190 parts of 1.5-naphtalindisulfosaurem sodium, mol. Weight 332, until the reaction is complete;
it is then filtered off and the diazo salt is dried at moderate temperature and, under certain circumstances, brought into commercial form by mixing it with suitable dyeing auxiliaries. These additives can also be added to the still moist diazo salt.
