Description

  

      Verfahren    zur     Herstellung        eines    neuen     wasserlöslichen        Salzes    einer     organischen          Stickstoffverbindung.       Die vorliegende Erfindung betrifft ein  Verfahren zur Herstellung eines neuen was  serlöslichen Salzes einer organischen Stick  stoffverbindung, welches dadurch gekenn  zeichnet ist, dass man die nach dem Verfah  ren gemäss Patentanspruch des Schweiz.     Pa-          tentes    Nr.

   253709 aus     Triäthylentetramin    und       Dicyandiamid    erhältliche Base in wässeriger  Lösung in ihr schwefelsaures     Salz    überführt  und hernach trocknet.  



  Das neue     Salz    ist ein     wasserlösliches,    hel  les, nicht hygroskopisches Pulver, das als     sol-          ehes    oder in Form eine     wasserlöslichen    Kup  ferkomplexes befähigt ist, die Echtheit von  Färbungen mit Substantiven Farbstoffen zu  verbessern.  



  <I>Beispiel:</I>  50 g der nach dem Beispiel des Schweiz.  Patentes     Nr.253709    hergestellten Base wer  den pulverisier und in 40 g Wasser bei  30 C aufgeschlämmt. 18,5 g Schwefelsäure,  d =1,84, werden in 20     em3    Wasser verdünnt  und gekühlt. Diese Säure wird unter gutem  Rühren in die Aufschlämmung der Base ein  getragen. Die     Neutralisationstemperatur    soll  50  C nicht übersteigen. Sie wird durch Zu  gabe von Eis     gegebenenfalls    herabgesetzt.    Nach beendeter Neutralisation wird noch  eine Stunde weiter gerührt und das Ganze  bei 70 bis 90  C im Vakuum zur Trockne ver  dampft.

   Man erhält ein wasserlösliches, helles,  nicht hygroskopisches Pulver, das als solches  oder in Form eines wasserlöslichen Kupfer  komplexes befähigt ist, die Echtheit von Fär  bungen mit Substantiven Farbstoffen zu ver  bessern.



      Process for the preparation of a new water-soluble salt of an organic nitrogen compound. The present invention relates to a method for the production of a new water-soluble salt of an organic nitrogen compound, which is characterized in that according to the method according to the Swiss patent claim. Patent No.

   253709 base obtainable from triethylenetetramine and dicyandiamide is converted into its sulfuric acid salt in aqueous solution and then dried.



  The new salt is a water-soluble, bright, non-hygroscopic powder which, as such or in the form of a water-soluble copper complex, is capable of improving the fastness of dyeings with nouns dyes.



  <I> Example: </I> 50 g according to the example of Switzerland. Patent No. 253709 prepared base who pulverized and slurried in 40 g of water at 30 C. 18.5 g sulfuric acid, d = 1.84, are diluted in 20 cubic meters of water and cooled. This acid is carried into the base slurry with thorough stirring. The neutralization temperature should not exceed 50 ° C. It may be reduced by adding ice. When the neutralization is complete, stirring is continued for an hour and the whole is evaporated to dryness at 70 to 90 ° C. in vacuo.

   A water-soluble, light-colored, non-hygroscopic powder is obtained which, as such or in the form of a water-soluble copper complex, is capable of improving the fastness of dyeings with nouns dyes.
