Description

  

  Verfahren zur Darstellung eines neuen     Aminoketons.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines  neuen     Aminoketons,    dadurch gekennzeichnet,  dass man     p-Chlor-ms-hexadecyldesoxybenzoin,     erhalten durch Umsetzung der     Natriumver-          bindung    des     p-Chlordesoxybenzoins    mit     Ce-          tylbromid,

      mit     Dimethylamin    umsetzt und  auf das     entstandene        p-Dimethylamino-ms-          hegadecyl-desoxybenzoin        Dimethylsulfat        ein-          wirken    lässt.

   Das Endprodukt,     p-Trimethyl-          ammonium-ms        -hegadeeyl-        desogybenzoin-me-          thylsulfat,        bildet    eine     wachsartige,    in Wasser  klar     lösliche    Masse und eignet sich     in    hervor  ragendem Masse zum Weichmachen von     na-          tiver    und umgefällter     Cellulose.     



  <I>Beispiel:</I>  45,4 Teile des     p-Chlor-ms-hegadecyl-des-          ogybenzoins    vom     Kp,,    3 =<B>270</B>     bis   <B>280'</B> C,  erhalten durch Umsetzung der     Natriumver-          bindung    des     p-Chlordesogybenzoins    mit     Ce-          tylbromid,

      werden mit einer Lösung von  20 Teilen     Dimethylamin    in 250     Volumteilen          Alkohol    und etwas     Kupferpulver        im    ge  schlossenen Gefäss 20     Stunden    auf 220' er  hitzt. Das abgeschiedene Produkt wird ab-    geputscht,     in    Benzol aufgenommen, das Kup  ferpulver entfernt und die     Lösung    wieder  eingedampft.  



  28 Teile     p-Dimethylamino-ms-hexadecyl-          desoxybenzoin    werden mit 7     Teilen        Di-          methylsulfat    eine     Stunde    auf 125   erhitzt.  Es entsteht, eine     wachsartige    Masse, die in  Wasser klar löslich ist.



  Process for the preparation of a new aminoketone. The subject of the present additional patent is a process for the preparation of a new aminoketone, characterized in that p-chloro-ms-hexadecyldeoxybenzoin, obtained by reacting the sodium compound of p-chlorodeoxybenzoin with cetyl bromide,

      reacted with dimethylamine and allowed to act on the resulting p-dimethylamino-ms- hegadecyl-deoxybenzoin dimethyl sulfate.

   The end product, p-trimethylammonium-ms -hegadeeyl-desogybenzoin-methylsulfate, forms a waxy mass that is clearly soluble in water and is excellently suited for the softening of native and reprecipitated cellulose.



  <I> Example: </I> 45.4 parts of p-chloro-ms-hegadecyl-des-ogybenzoins with a bp ,, 3 = <B> 270 </B> to <B> 280 '</B> C obtained by reacting the sodium compound of p-chlorodesogybenzoin with cetyl bromide,

      are with a solution of 20 parts of dimethylamine in 250 parts by volume of alcohol and a little copper powder in a closed vessel ge for 20 hours at 220 'he is heated. The deposited product is washed off, taken up in benzene, the copper powder removed and the solution evaporated again.



  28 parts of p-dimethylamino-ms-hexadecyldeoxybenzoin are heated to 125 with 7 parts of dimethyl sulfate for one hour. The result is a waxy mass that is clearly soluble in water.
