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        (CHs    :     NH2    : Cl = 1 : 2 : 5) mit  einem     1.5-naphtalindisulfosauren    Metallsalz  umsetzt.  



  Das so erhaltene neutrale     1.5-Naphtalin-          disulfonat    des     diazotierten        Chlortoluidins          (CHs    :     NHa    :

   Cl = 1 : 2 : 5) von zum Beispiel       42        %        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 zweck  mässig mit geeigneten, die Ausfärbungen, die  Löslichkeit und die Haltbarkeit günstig be  einflussenden Zusätzen und     Färbereihilfsmit-          teln,    wie zum Beispiel Aluminiumsulfat oder  Alaun,

       arylsulfonsauren    Metallsalzen und  dergleichen noch auf einen handelsüblichen       Diazogehalt    eingestellt wird.  



  <I>Beispiel:</I>  Eine aus 142 Teilen     5-Chlor-2-amino-          1-toluol    in üblicher Weise hergestellte kon-    zentrierte Lösung des     Diazochlorids    wird mit  185 Teilen 1 . 5     naphtalindisulfosaurem    Na  trium,     Mol.        Gew.    332, bis zur völligen Umset  zung verrührt; dann wird     abfiltriert    und das     Di--          azosalz    bei mässiger Temperatur getrocknet und  unter Umständen durch Vermischen mit ge  eigneten     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 (CHs: NH2: Cl = 1: 2: 5) is reacted with a 1.5-naphthalene disulphonic acid metal salt.



  The neutral 1,5-naphthalene disulfonate of diazotized chlorotoluidine (CHs: NHa:

   Cl = 1: 2: 5) with a chlorotoluidine base content of 42%, for example, forms a white, easily durable, soluble, diazo salt preparation which is suitable for dyeing primed cotton and which can be used with suitable dyes , additives and dyeing auxiliaries that have a beneficial effect on solubility and shelf life, such as aluminum sulfate or alum,

       arylsulfonic acid metal salts and the like is still set to a commercial Diazo content.



  <I> Example: </I> A concentrated solution of the diazo chloride prepared in the usual way from 142 parts of 5-chloro-2-amino-1-toluene is mixed with 185 parts of 5 naphtalindisulfosaurem sodium, mol. Wt. 332, stirred until complete implementation; 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.

PATENTANSPRUCH: Verfahren zur Herstellung eines Diazo- salzpräparates für Färberei und Druckerei, dadurch gekennzeichnet, dass man die wie üblich hergestellte mineralsaure Diazosalz- lösung von Chlortoluidin (CHo : NH2 : Cl = 1:2:5) mit einem 1.5-naphtalindisulfosau- ren Metallsalz umsetzt. PATENT CLAIM: A process for the production of a diazo salt preparation for dyeing and printing, characterized in that the normally produced mineral acid diazo salt solution of chlorotoluidine (CHo: NH2: Cl = 1: 2: 5) is mixed with a 1.5-naphthalene disulphonic acid metal salt implements. Das so erhaltene neutrale 1.5-Naph- talindisulfonat des diazotierten Chlortoluidins (CHs : NH2 : Cl =1:2:5) bildet ein weisses am Licht und beim Lagern sich bräunendes, gut haltbares, lösliches, unmittelbar zum .Ausfärben grundierter Baumwolle geeignetes Diazosalzpräparat. U NTERANSPRüCHE i. The neutral 1,5-naphthalenedisulfonate of the diazotized chlorotoluidine (CHs: NH2: Cl = 1: 2: 5) obtained in this way forms a white diazo salt preparation that is tanned when exposed to light and when stored, easily durable, soluble and directly suitable for coloring primed cotton.
