Description

  

  Verfahren zur Darstellung     eines    basischen Derivates des     Cyanamids.       Es wurde gefunden, dass man zu dem  im Hauptpatent beschriebenen     Bisdiäthyl-          aminoäthyl-cy        ana.mid    auch gelangen kann,       wenn    man     Halogenätliyldiäthylamin    auf  Metallsalze des     Cyanamids    einwirken lässt.

           Beispiel:       43 Gewichtsteile     Cyanamidnatrium    wer  den in wässeriger Lösung mit<B>136</B> Gewichts  teilen     Chloräthyldiäthylamin    unter     gelinder          Erwärmung    verrührt. Die     entstandene    Base  wird in Äther aufgenommen und in üblicher       'N#@reise    isoliert. Sie besitzt die im Haupt  patent beschriebenen Eigenschaften.  



  Man kann auch in Gegenwart anderer  Lösungsmittel, wie zum Beispiel Alkohol,       arbeiten.    An Stelle des     l@Tatriumsalzes    des       Cyanamids    lassen sich auch beliebige andere  Salze, wie zum Beispiel das Kalk- oder das  Silbersalz, verwenden.

   Ebenso lässt sich das       Chloräthyldiäthy        lamin    durch andere     Ilalo-          enä.thyldiäthylamine    ersetzen, oder diese  können erst im Reaktionsgemisch aus     Chlor-          :litliyIdiäthylamin,    zum Beispiel durch Zusatz       kleinerer    oder grösserer Mengen Brom-     oder       Todalkali, intermediär erzeugt werden. Statt  der freien Halogenbasen     verwendet    man  zweckmässig ihre Salze und setzt die Basen  während der Reaktion, zum Beispiel durch  Zusatz von     Alkalikarbonat,    in Freiheit.



  Process for the preparation of a basic derivative of cyanamide. It has been found that the bisdiäthylaminoäthyl-cy ana.mid described in the main patent can also be obtained if haloethyl diethylamine is allowed to act on metal salts of cyanamide.

           Example: 43 parts by weight of sodium cyanamide are stirred in an aqueous solution with 136 parts by weight of chloroethyl diethylamine under gentle heating. The resulting base is taken up in ether and isolated in the usual way. It has the properties described in the main patent.



  You can also work in the presence of other solvents, such as alcohol. Any other salts, such as the lime or silver salt, can also be used instead of the sodium salt of cyanamide.

   Likewise, the chloroethyl diethylamine can be replaced by other Ilaloenä.thyldiäthylamine, or these can only be produced as an intermediate in the reaction mixture of chloro-: lithium diethylamine, for example by adding smaller or larger amounts of bromine or dead alkali. Instead of the free halogen bases, it is expedient to use their salts and to set the bases free during the reaction, for example by adding alkali metal carbonate.
