Description

  

  Verfahren zur Herstellung eines     Diazosalzpräparates    für Färberei und     Bruekerei.       Es wurde gefunden, dass man ein gut  haltbares     Diazosalzpräpa.rat    für Färberei  und Druckerei erhält, wenn man die, wie  üblich, hergestellte mineralsaure     Diazosalz-          lösung    von     4-Clilor-2-amino-l-diphenyläther     der Formel:  
EMI0001.0007     
    mit einem     1.5-naphtalindisulfosauren    Me  tallsalz umsetzt.  



  Das so erhaltene neutrale     1.5-Naphta-          lindisulfonat    des     diazotierten        Chloramino-          phenyläthers    von zum Beispiel 35 % Gehalt  an     Chloraminophenylätherbase    bildet ein  bräunliches, gut haltbares, lösliches, unmit  telbar zum Ausfärben grundierter Baum  wolle geeignetes     Diazosalzpräparat,    das  zweckmässig mit geeigneten, die Ausfärbun  gen, die Löslichkeit und die Haltbarkeit  günstig beeinflussenden Zusätzen und     Fär-          bereihilfsmitteln,    wie z.

   B.     Aluminiumsulfat     oder Alaun,     arylsulfosauren    Metallsalzen und       dergleichen,    noch auf einen handelsüblichen       Diazogehalt    eingestellt wird.    <I>Beispiel:</I>  Eine aus 220 Teilen     4-Chlor-2-amino-l-          diphenyläther    in üblicher Weise hergestellte  konzentrierte Lösung des     Diazochlorids    wird  mit 195 Teilen     1.5-naphtalindisulfosaurem     Natrium,     Mol.        Gew.    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 brewing. It has been found that a diazo salt preparation that can be kept well for dyeing and printing is obtained if the mineral acid diazo salt solution of 4-Clilor-2-amino-1-diphenyl ether of the formula, prepared as usual, is obtained:
EMI0001.0007
    with a 1.5-naphtalindisulfosauren metal salt.



  The neutral 1,5-naphthalene disulfonate of the diazotized chloraminophenyl ether obtained in this way, for example with a chloraminophenyl ether base content of 35%, forms a brownish, well-preserved, soluble, directly suitable for coloring primed cotton diazo salt preparation, which is expediently colored with suitable, coloring the solubility and shelf life of additives and dyeing auxiliaries, such as

   B. aluminum sulfate or alum, aryl sulfonic acid metal salts and the like, is still set to a commercially available Diazo content. <I> Example: </I> A concentrated solution of the diazo chloride prepared in the usual way from 220 parts of 4-chloro-2-amino-1-diphenyl ether is mixed with 195 parts of sodium 1,5-naphthalene disulphonic acid, mol. Wt. 332, until complete Implementation 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.
