Description

  

  Verfahren zur Herstellung einer wasserlöslichen organischen     Stickstoffverbindung.       Im Hauptpatent ist ein Verfahren be  schrieben, bei welchem     Triäthylentetramin     und     Dicyandiamid    in Abwesenheit von Was  ser bei erhöhter Temperatur unter Abspal  tung von Ammoniak miteinander zur Reak  tion gebracht werden.  



  Es hat sich nun gezeigt, dass man ähnlich  wirkende Verbindungen erhält, wenn man an  Stelle von     Triäthylentetramin    eine äquiva  lente Menge eines Gemisches von     Polyäthy-          lenpoly        aminen    vom     Kplo_"    103 bis 2200 C,  wie es bei der Destillation des Umsetzungs  produktes aus     Äthylenchlorid    und Ammoniak  nach Aufarbeitung desselben anfällt, mit     Di-          cyandiamid    in Abwesenheit von Wasser, ge  gebenenfalls in Anwesenheit von nichtwässeri  gen Lösungsmitteln, bei erhöhter Temperatur  unter Abspaltung von Ammoniak umsetzt.  



  Das Produkt ist. eine basische, schwach  gelb gefärbte,     pulverisierbare,    wasserlösliche  Masse, die mit Hilfe geeigneter organischer  oder anorganischer Säuren in wasserlösliche  Salze übergeführt werden kann. Das basische  Produkt wie auch dessen wasserlösliche Salze  eignen sich als solche oder zusammen mit was  serlöslichen Verbindungen der     mehrwertigen     Metalle, wie Kupfer, zur Verbesserung der       Echtheitseigensehaften    von Färbungen     finit     Substantiven Farbstoffen, zur Herstellung  von Pigmenten oder zur     Animalisierung        zellu-          losischer    Fasern.

   Sie besitzen ausserdem die    Eigenschaft, saure Farbstoffe aus ihren wäs  serigen Lösungen zu fällen.         Beispiel:     In einem geeigneten Rührkolben werden  zum Beispiel 20,6 g     Polyäthylenpolyamin,          Kplo_i2    103 bis 2200 C, und 16,8 g     Dieyan-          diamid    gemischt und 3 bis 5 Stunden bei 125  bis 165  C gehalten. Eine Probe soll noch  immer wasserlöslich sein. Wird die Masse zu  dick, so wird der     Rührer    abgestellt und die  selbe ohne Rühren weitererhitzt. Das erhal  tene Kondensationsprodukt ist eine basische,  schwach gelb gefärbte Masse, die nach dem  Erkalten pulverisiert werden kann.

   Es kann  als solche oder in Form eines wasserlöslichen  Salzes oder Kupferkomplexes zur Anwendung  gelangen.



  Process for producing a water-soluble organic nitrogen compound. The main patent describes a process in which triethylenetetramine and dicyandiamide are reacted with each other in the absence of what water at elevated temperature with elimination of ammonia.



  It has now been shown that compounds with a similar effect are obtained if, instead of triethylenetetramine, an equivalent amount of a mixture of polyethylene polyamines from Kplo_ "103 to 2200 C, as is the case with the distillation of the reaction product of ethylene chloride and ammonia after working up the same, reacted with dicyandiamide in the absence of water, optionally in the presence of non-aqueous solvents, at elevated temperature with the elimination of ammonia.



  The product is. a basic, pale yellow, pulverizable, water-soluble mass which can be converted into water-soluble salts with the aid of suitable organic or inorganic acids. The basic product as well as its water-soluble salts are suitable as such or together with water-soluble compounds of the polyvalent metals, such as copper, to improve the fastness properties of finite substantive dyes, for the production of pigments or for the animalization of cellulosic fibers.

   They also have the property of precipitating acidic dyes from their aqueous solutions. Example: In a suitable stirred flask, for example, 20.6 g of polyethylene polyamine, Kplo_i2 103 to 2200 C, and 16.8 g of dieyaniamide are mixed and held at 125 to 165 C for 3 to 5 hours. A sample should still be soluble in water. If the mass becomes too thick, the stirrer is switched off and the same is further heated without stirring. The condensation product obtained is a basic, pale yellow-colored mass that can be pulverized after cooling.

   It can be used as such or in the form of a water-soluble salt or copper complex.
