Description

  

  Verfahren zur Herstellung eines     Diazosalzpräparates    für Färberei und     Druclcerei.       Es wurde gefunden, dass man ein gut  haltbares     Diazosalzpräparat    für Färberei und  Druckerei erhält, wenn man die wie üblich  hergestellte mineralsaure     Diazosalzlösung    von       4-Chlor-2-amino-l-anisol    mit einem     1.5-naph-          talindisulfosauren    Metallsalz umsetzt.  



  Das so erhaltene neutrale     1.5-Naphtalin-          disulfonat    des dianotierten     Chloraminoanisols          von        zum        Beispiel        32        %        Gehalt        an        Chlor-          aminoanisolbase    bildet ein fast weisses, gut  haltbares, lösliches, unmittelbar zum Aus  färben grundierter Baumwolle geeignetes     Di-          azosalzpräparat,    das zweckmässig mit geeig  neten, die Ausfärbungen,

   die Löslichkeit und  die Haltbarkeit günstig beeinflussenden Zu  sätzen und     Färbereihilfsmitteln,    wie zum  Beispiel Aluminiumsulfat oder Alaun,     aryl-          sulfosauren    Metallsalzen und dergleichen noch  auf 'einen handelsüblichen     Diazogehalt    einge  stellt wird.  



       Beispiel     Eine aus 158 Teilen     4-Chlor-2-amino-l-          anisol    in üblicher Weise hergestellte konzen-         trierte    Lösung des     Diazochlorids    wird mit  185 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     Diazo-          salz    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 conventionally prepared mineral acid diazo salt solution of 4-chloro-2-amino-1-anisole is reacted with a 1,5-naphthalenedisulfonic acid metal salt.



  The neutral 1,5-naphthalene disulfonate of the dianotized chloraminoanisole obtained in this way, for example 32% chloroaminoanisole content, forms an almost white, well-preserved, soluble, diazo salt preparation suitable for dyeing primed cotton, which is conveniently mixed with the Discoloration,

   the solubility and shelf life of additives and dyeing auxiliaries, such as aluminum sulfate or alum, aryl sulfonic acid metal salts and the like, which have a beneficial effect on the shelf life, are still set to a commercial diazo content.



       EXAMPLE A concentrated solution of the diazo chloride prepared in a conventional manner from 158 parts of 4-chloro-2-amino-l-anisole is trium with 185 parts of 1.5-naphthalene disulfonic acid, molecular weight 332; Stirred until complete conversion - then it is filtered off and the diazo salt is dried at a 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.
