Description

  

  Verfahren zur Herstellung eines     Diazosalzpräparates    für Färberei und Druckerei.       a       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-anisol,mit    einem     1.5-naph-          talindisulfosauren    Metallsalz umsetzt.  



  Das so erhaltene neutrale     1.5-Naphtalin-          disulfonat    des dianotierten     5-Nitro-2-amino-          1-anisols        von        zum        Beispiel        43        %        Gehalt        an          Nitroaminoanisolbase    bildet ein gelbes, 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 168 Teilen     5-Nitro-2-amino-l-          anisol    in üblicher Weise hergestellte konzen-         trierte    Lösung des     Diazochlorids    wird mit  189 Teilen     1.5-naphtalindisulfosaurem    Na  trium,     Molekulargewicbt    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. a It has been found that a diazo salt preparation that can be kept well for dyeing and printing is obtained if the normally prepared mineral acid diazo salt solution of 5-nitro-2-amino-1-anisole is reacted with a 1,5-naphthalenedisulfonic acid metal salt.



  The neutral 1,5-naphthalene disulfonate of the dianotized 5-nitro-2-amino-1-anisole obtained in this way, for example with a content of 43% nitroaminoanisole base, forms a yellow, well-preserved, soluble diazo-salt preparation suitable immediately for coloring primed cotton, the appropriate with suitable, the coloring

   the solubility and shelf life of additives and dyeing auxiliaries, such as aluminum sulfate or alum, aryl sulfonic acid metal salts and the like, is adjusted to a commercially available diazo content.

      <I> Example </I> A concentrated solution of the diazo chloride prepared in the usual way from 168 parts of 5-nitro-2-amino-l-anisole is mixed with 189 parts of sodium 1,5-naphthalene disulphonic 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.
