Description

  

  Verfahren zur Herstellung eines     Diazosalzpräparates    für Färberei     und.    Druckerei.    Es     wurde    gefunden, dass man ein gut  haltbares     Dia.zosalzpräparat    für Färberei  und Druckerei erhält,     wenn    man die, wie  üblich, hergestellte     mineralsaure        Diazosalz-          lösung    von     4.4'-Diamino-3.3'-dimet-.hoxy-          diphenyl    mit einem     1.5-naphtalindisulfo-          sauren    Metallsalz umsetzt.  



  Das so erhaltene neutrale 1.     5-Naphtalin-          disulfonat    des     diazotierten        Dianisidins    von  zum Beispiel 35 % Gehalt an     Dianisidin-          base        bildet    ein graubraunes, gut haltbares,  lösliches, unmittelbar zum Ausfärben grun  dierter Baumwolle geeignetes     Diazosa.lzprä-          parat,    das zweckmässig mit geeigneten, die  Ausfärbungen, die Löslichkeit und die Halt  barkeit günstig beeinflussenden Zusätzen  und     Färbereihilfsmitteln,    wie z. B.

   Alumi  nium oder Alaun,     arylsulfonsauren    Metall  salzen und dergleichen, noch auf einen han  delsüblichen     Diazogehalt    eingestellt wird.  <I>Beispiel:</I>  Eine aus 244 Teilen 4.     4'-Diamino-3.    3'  dimethoxydiphenyl in     üblicher    Weise her-    gestellte konzentrierte Lösung des     Diazo-          chlorids    wird mit 185 Teilen 1.     5-naphtalin-          disulfosaurem    Natrium,     Mol.        Gew.    332, bis  zur völligen Umsetzung verrührt;

   dann wird       abfiltriert    und das     Diazosalz    bei mässiger  Temperatur getrocknet und unter Umstän  den durch Vermischen mit geeigneten     Fär-          bereihilfsmitteln    in handelsfertige Form ge  bracht. Diese Zusätze können auch dem noch  feuchten     Diazosalz    zugemischt werden.



  Process for the production of a diazo salt preparation for dyeing and. Printing house. It has been found that a long-lasting Dia.zo salt preparation for dyeing and printing is obtained if the mineral acid diazo salt solution of 4.4'-diamino-3.3'-dimet-.hoxydiphenyl with a 1.5-naphthalene disulfo, prepared as usual, is obtained - converts acidic metal salt.



  The neutral 1,5-naphthalene disulfonate of the diazotized dianisidine obtained in this way, for example 35% dianisidine base content, forms a gray-brown, easily durable, soluble diazosa preparation which is suitable for dyeing primed cotton and which is expediently prepared with suitable , the discoloration, the solubility and the availability favorably influencing additives and dyeing auxiliaries, such as. B.

   Aluminum or alum, metal arylsulfonic acid salts and the like, nor is it adjusted to a commercially available diazo content. <I> Example: </I> One of 244 parts 4. 4'-Diamino-3. 3 'dimethoxydiphenyl concentrated solution of the diazo chloride prepared in the usual way is stirred with 185 parts of 1.5-naphthalene-disulphonic acid sodium, mol. Wt. 332, until the reaction is complete;

   It is then 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 it with suitable dyeing auxiliaries. These additives can also be added to the still moist diazo salt.
