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 Chlortoluidin (CH a : NH 2 : Cl = 1 : 2 : 6) mit einem 1.5-naplitalindisulfosauren Metall salz umsetzt.
Das so erhaltene neutrale 1.5-Naphtalin- disulfonat des diazotierten Chlortoluidins (CH s : NH2 :
C1=1 : 2 : 6) von zum Beispiel 42'/o Gehalt an Chlortoluidinbase bildet ein weisses, am Licht und beim Lagern sich bräunendes gut haltbares, lösliches, unmittel bar zum Ausfärben grundierter Baumwolle geeignetes Diazosalzpräparat, das zweckmässig mit geeigneten, die Ausfärbungen, die Lös lichkeit und die Haltbarkeit günstig beein flussenden 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 142 Teilen 6-Chlor-2-amino-l- toluol in üblicher Weise hergestellte konzen trierte Lösung des Diazochlorids wird mit 185 Teilen 1.5-naphtalindisulfosaurerri Na trium, DIolekulargewicht 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 Zusätze können auch dem noch feuchten Diazosalz zugemischt werden.
Process for the production of a diazo salt preparation for dyeing and printing. It has been found that a diazo salt preparation with good stability for dyeing and printing is obtained if the normally prepared mineral acid diazo salt solution of chlorotoluidine (CH a: NH 2: Cl = 1: 2: 6) is reacted with a 1.5-naplitalindisulfonic acid metal salt.
The neutral 1,5-naphthalene disulfonate of diazotized chlorotoluidine (CH s: NH2:
C1 = 1: 2: 6) with a chlorotoluidine base content of 42%, for example, forms a white, soluble, soluble diazo salt preparation that is easy to keep in the light and tans on storage, suitable for dyeing primed cotton, which is conveniently combined with suitable coloring , additives and dyeing auxiliaries that favorably influence the solubility and shelf life, such as aluminum sulfate or alum, aryl sulfonic acid metal salts and the like, are adjusted to a commercially available diazo content.
<I> Example </I> A concentrated solution of the diazo chloride prepared in the customary manner from 142 parts of 6-chloro-2-amino-l-toluene is stirred with 185 parts of sodium 1.5-naphthalene disulfosaurate, molecular weight 332, until complete reaction ; 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.
