Description

  

  Verfahren zur Herstellung des neuen     Bis.(ss,y-dioxy-propyl)-amins.       Es wurde gefunden, dass man zum neuen  Bis-     (ss,y-dioxy-propyl)        -amin    gelangt, wenn man  einen von einer     Carbonylverbindung    sich ab  leitenden     cyclisehen    Äther des     Bis-(ss,y-dioxy-          propyl)-amins    einer     hydrolytischen        Spaltring     unterwirft.  



  Als     cyclisehe    Äther der angeführten Art  können Äther     verwendet.    werden, die sieh zum  Beispiel von Aldehyden, wie     Acetaldehyd,    oder       Ketonen,    wie Aceton, ableiten.  



  Die     hydrolytische        Spaltung    kann durch  Erhitzen mit. verdünnten Mineralsäuren, z. B.  mit 10 %     iger        Schwefelsäure,    vorgenommen  werden.  



       Das    neue Amin bildet eine amorphe, wei  che Masse, die in Wasser und Alkohol leicht  löslich ist.  



  Das neue Amin kann als Zwischenprodukt,  z. B. zur Herstellung von     Textilhilfsstoffen,     verwendet werden.    <I>Beispiel:</I>  50 Teile der Base der Formel  
EMI0001.0020     
    werden in 200     Volumteilen    10 %     iger    Schwefel  säure gelöst. Die Lösung wird im Laufe von  30     Minuten        zum    Kochen     erhitzt,    worauf der  anfangs starke C er ich nach Aceton ver  schwindet. Nach Zugabe von     Barimncarbonat     bis zum Verschwinden der sauren Reaktion  wird filtriert.

   Das Filtrat     -wird    im     Valium     eingedampft; man erhält die Base     als    dickes,  bräunlich gefärbtes Öl, das nach und nach zu       einer    amorphen, weichen Masse erstarrt. Die  Base ist in Wasser und     Alkohol    leicht löslich,  hingegen unlöslich in Äther. Die wässerige  Lösung reagiert stark     alkalisch.  



  Process for the preparation of the new bis. (Ss, y-dioxy-propyl) -amine. It has been found that the new bis- (ss, y-dioxy-propyl) -amine is obtained if a cyclic ether of the bis- (ss, y-dioxy-propyl) -amine of a hydrolytic one derived from a carbonyl compound is used Split ring subjects.



  Ethers can be used as cyclic ethers of the kind mentioned. derived from aldehydes such as acetaldehyde or ketones such as acetone.



  The hydrolytic cleavage can be achieved by heating. dilute mineral acids, e.g. B. with 10% sulfuric acid.



       The new amine forms an amorphous, soft mass that is easily soluble in water and alcohol.



  The new amine can be used as an intermediate, e.g. B. for the production of textile auxiliaries used. <I> Example: </I> 50 parts of the base of the formula
EMI0001.0020
    are dissolved in 200 parts by volume of 10% sulfuric acid. The solution is heated to a boil over the course of 30 minutes, after which the initially strong carbon disappears after acetone. After adding barimn carbonate until the acidic reaction has disappeared, it is filtered.

   The filtrate is evaporated in the Valium; the base is obtained as a thick, brownish-colored oil which gradually solidifies to form an amorphous, soft mass. The base is easily soluble in water and alcohol, but insoluble in ether. The aqueous solution has a strongly alkaline reaction.
