Description

  

  Verfahren zur     Iier    Stellung 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       3-Nitro-4-ainirio-l-anisol    mit einem     1.5-naph-          talindisulfosauren    Metallsalz umsetzt.  



  Das so erhaltene neutrale     1.5-Naphtalin-          disulfonat    des dianotierten     3-Nitro-4-amino-          1-anisols        von        zum        Beispiel        48%        Gehalt        au          Nitroaminoanisolbase    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 Bei  spiel Aluminiumsulfat oder Alaun,     arylsul-          fonsauren    Metallsalzen und dergleichen noch  auf einen handelsüblichen     Diazogehält    einge  stellt wird.

      <I>Beispiel:</I>  Eine aus 168 Teilen     3-Nitro-4-amino-l-          anisol    in üblicher Weise hergestellte konzen-         trierte    Lösung des     Diazocblorids    wird mit  189 Teilen     1.5-naphtalindisalfosanrem    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     finit    geeigneten     Färbereihilfastoffen     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 customarily prepared mineral acid diazo salt solution of 3-nitro-4-ainirio-1-anisole is reacted with a 1,5-naphthalenedisulfonic acid metal salt.



  The neutral 1,5-naphthalene disulfonate of the dianotized 3-nitro-4-amino-1-anisole obtained in this way, for example with a nitroaminoanisole content of 48%, forms an almost white, well-preserved, soluble, diazo salt preparation suitable immediately for coloring primed cotton ;

      which is expediently set to a commercially available slide container with suitable additives and dyeing auxiliaries that have a beneficial effect on the color, solubility and shelf life, such as aluminum sulfate or alum, arylsulfonic acid metal salts and the like.

      <I> Example: </I> A concentrated solution of the diazo chloride prepared in the usual way from 168 parts of 3-nitro-4-amino-l-anisole is mixed with 189 parts of 1.5-naphthalene disalfosanrem sodium, molecular weight 332, to complete Implementation stirred; Then it is filtered off and the diazo salt is dried at a moderate temperature and, under certain circumstances, brought into a ready-to-trade form by mixing finite suitable dyeing auxiliary substances.

   These additives can also be added to the still moist diazo salt.

UNTERANSPRÜCHE: 1. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man nach beendeter Reaktion noch eineu Färbereihilfsstoff zu setzt. Z. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man nach beendeter Reaktion noch Aluminiumsulfat zusetzt. 3. The neutral 1.5-napbtalin disulfonate of the dianotized 3-nitro-4-amino-l-anisole obtained in this way forms an almost white, easily stable, soluble diazo salt preparation that is immediately suitable for coloring primed space wool. SUBClaims: 1. Method according to claim, characterized in that, after the reaction has ended, a dyeing aid is added. Z. The method according to claim, characterized in that aluminum sulfate is added after the reaction has ended. 3. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man nach beendeter Reaktion noch Alaun zusetzt. 4. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man nach beendeter Reaktion noch ein arylsulfonsaures Metall salz zusetzt. Process according to patent claim, characterized in that alum is also added after the reaction has ended. 4. The method according to claim, characterized in that, after the reaction has ended, an aryl sulfonic acid metal salt is added.
