Description
Verfahren zur Herstellung eines Diazosalzpräparates für Färberei und Bruekerei. Es wurde gefunden, dass man ein gut haltbares Diazosalzpräpa.rat für Färberei und Druckerei erhält, wenn man die, wie üblich, hergestellte mineralsaure Diazosalz- lösung von 4-Clilor-2-amino-l-diphenyläther der Formel:
EMI0001.0007
mit einem 1.5-naphtalindisulfosauren Me tallsalz umsetzt.
Das so erhaltene neutrale 1.5-Naphta- lindisulfonat des diazotierten Chloramino- phenyläthers von zum Beispiel 35 % Gehalt an Chloraminophenylätherbase bildet ein bräunliches, gut haltbares, lösliches, unmit telbar zum Ausfärben grundierter Baum wolle geeignetes Diazosalzpräparat, das zweckmässig mit geeigneten, die Ausfärbun gen, die Löslichkeit und die Haltbarkeit günstig beeinflussenden Zusätzen und Fär- bereihilfsmitteln, wie z.
B. Aluminiumsulfat oder Alaun, arylsulfosauren Metallsalzen und dergleichen, noch auf einen handelsüblichen Diazogehalt eingestellt wird. <I>Beispiel:</I> Eine aus 220 Teilen 4-Chlor-2-amino-l- diphenyläther in üblicher Weise hergestellte konzentrierte Lösung des Diazochlorids wird mit 195 Teilen 1.5-naphtalindisulfosaurem Natrium, Mol. Gew. 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 brewing. It has been found that a diazo salt preparation that can be kept well for dyeing and printing is obtained if the mineral acid diazo salt solution of 4-Clilor-2-amino-1-diphenyl ether of the formula, prepared as usual, is obtained:
EMI0001.0007
with a 1.5-naphtalindisulfosauren metal salt.
The neutral 1,5-naphthalene disulfonate of the diazotized chloraminophenyl ether obtained in this way, for example with a chloraminophenyl ether base content of 35%, forms a brownish, well-preserved, soluble, directly suitable for coloring primed cotton diazo salt preparation, which is expediently colored with suitable, coloring the solubility and shelf life of additives and dyeing auxiliaries, such as
B. aluminum sulfate or alum, aryl sulfonic acid metal salts and the like, is still set to a commercially available Diazo content. <I> Example: </I> A concentrated solution of the diazo chloride prepared in the usual way from 220 parts of 4-chloro-2-amino-1-diphenyl ether is mixed with 195 parts of sodium 1,5-naphthalene disulphonic acid, mol. Wt. 332, until complete Implementation stirred;
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.
