Description

  

  Verfahren zur Darstellung eines neuen     Aminoketons.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Darstellung eines  neuen     Aminoketons,    dadurch gekennzeichnet,  dass man     p-Chlorlaurophenon    mit     Dimethyl-          amin    und das entstandene     p-Dimethylamii)o-          laurophenon    mit     Dimethylsulfat    umsetzt.

   Die  neue Verbindung, das     p-Trimethylammonium-          laurophenonmethylsufat,    eine bräunliche, dick  flüssige Masse, ist in Wasser klar löslich und  eignet sich als Netzmittel, als Mittel zur  Verbesserung der Wasserechtheit von Direkt  färbungen, als Abziehmittel für     Naphtol-AS-          Färbungen,    als Mottenschutzmittel und be  sitzt gute     fungizide    und bakterizide Eigen  schaften.  



  <I>Beispiel:</I>  250 Teile Chlorbenzol werden mit 100  Teilen Aluminiumchlorid versetzt und unter  Rühren 109 Teile     Palmkernfettsäurecblorid          zugetropft.    Nach 15 Stunden bei 70-80    wird abgekühlt, in Wasser gegossen und mit  Wasserdampf destilliert, bis alles überschüs  sige Chlorbenzol verschwunden ist. Zurück    bleiben 100 Teile     p-Chlorlaurophenon    vom       Kpi4    = 19<B>5</B>-230<B>0</B> C.  



  50 Teile dieser     Verbindung    werden mit  einer alkoholischen Lösung von 40 Teilen       Dimethylamin    in 250     Volumteilen    Alkohol  und etwas Kupferpulver im     Autoklaven    20  Stunden auf     220-2301    erhitzt. Nach Ent  fernen des Kupferpulvers und Verjagen des  Lösungsmittels lässt sich das     p-Dimethyl-          aminolaurophenon    als gelbes<B>01</B> gewinnen,  das langsam erstarrt. Es ist in Salzsäure  klar löslich.     gp4    =     225-250'    C.  



  20 Teile     p-Dimethylaminolaurophenon    und  12 Teile     Dimethylsulfat    werden während 30  Minuten auf 120-130   erhitzt. Es bildet  sich das klar wasserlösliche     p-Trimethyl-          ammonium-laurophenon-methylsulfat    in Form  einer bräunlichen, dickflüssigen Masse.



  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-laurophenone is reacted with dimethylamine and the resulting p-dimethylamino) olaurophenone is reacted with dimethyl sulfate.

   The new compound, p-trimethylammonium laurophenone methyl sulfate, a brownish, thick liquid mass, is clearly soluble in water and is suitable as a wetting agent, as a means to improve the waterfastness of direct dyeings, as a stripping agent for naphthol-AS dyeings, as a moth repellent and has good fungicidal and bactericidal properties.



  <I> Example: </I> 250 parts of chlorobenzene are mixed with 100 parts of aluminum chloride and 109 parts of palm kernel fatty acid chloride are added dropwise with stirring. After 15 hours at 70-80 it is cooled, poured into water and distilled with steam until all the excess chlorobenzene has disappeared. What remains are 100 parts of p-chlorophenone from Kpi4 = 19 <B> 5 </B> -230 <B> 0 </B> C.



  50 parts of this compound are heated to 220-2301 in an autoclave with an alcoholic solution of 40 parts of dimethylamine in 250 parts by volume of alcohol and some copper powder. After removing the copper powder and driving off the solvent, the p-dimethylaminolaurophenone can be obtained as a yellow 01 that slowly solidifies. It is clearly soluble in hydrochloric acid. gp4 = 225-250 'C.



  20 parts of p-dimethylaminolaurophenone and 12 parts of dimethyl sulfate are heated to 120-130 for 30 minutes. The clear, water-soluble p-trimethylammonium-laurophenone-methylsulfate forms in the form of a brownish, viscous mass.
