Description
Verfahren zur Herstellung eines Diazosalzpräparates für Färberei und Druckerei. Es wurde gefunden, dass man ein gut haltbares. Diazosalzpräparat für Färberei und Druckerei erhält, wenn man die wie üblich hergestellte mineralsaure Diazosalzlösung von 5-Nitro-2-amino-l-toluol mit einem 1.5-naph- talindisulfosauren Metallsalz umsetzt.
Das so erhaltene neutrale 1.5-Naphtalin- disulfonat des diazotierten 5-Nitro-2-amino-l- toluols von zum Beispiel 28 /o Gehalt an Nitrotoluidinbase bildet ein gelbbraunes, gut haltbares, lösliches, unmittelbar zum Ausfär ben grundierter Baumwolle geeignetes Diazo- salzpräparat, das zweckmässig mit geeigneten, die Ausfärbungen, die Löslichkeit und die Haltbarkeit günstig beeinflussenden Zusätzen und Färbereihilfsmitteln, wie zum Beispiel Aluminiumsulfat oder Alaun,
arylsulfonsauren Metallsalzen und dergleichen noch auf einen handelsüblichen Diazogehalt eingestellt wird. <I>Beispiel</I> Eine aus 152 Teilen- 5-Nitro-2-amino-l- toluol in üblicher Weise hergestellte konzen trierte Lösung des Diazochlorids wird mit 200 Teilen 1.5-naphtalindisulfosaurem Na trium, Molekulargewicht 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 Di- azosalz zugemischt werden.
Process for the production of a diazo salt preparation for dyeing and printing. It has been found that you can get a well durable. Diazo salt preparation for dyeing and printing is obtained if the normally prepared mineral acid diazo salt solution of 5-nitro-2-amino-1-toluene is reacted with a 1,5-naphthalenedisulfonic acid metal salt.
The neutral 1,5-naphthalene disulfonate of the diazotized 5-nitro-2-amino-l-toluene obtained in this way with, for example, a nitrotoluidine base content of 28%, forms a yellow-brown, well-preserved, soluble diazotised salt preparation suitable immediately for dyeing primed cotton , expediently with suitable additives and dyeing auxiliaries, such as aluminum sulfate or alum, which have a beneficial effect on the color, the solubility and the shelf life,
arylsulfonic acid metal salts and the like is still set to a commercial Diazo content. <I> Example </I> A concentrated solution of the diazo chloride prepared in the usual way from 152 parts of 5-nitro-2-amino-l-toluene is trium with 200 parts of 1.5-naphthalene disulfonic acid, molecular weight 332, until complete conversion 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.
