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.
