Description

  

  Verfahren zur Darstellung eines neuen     Aminoketons.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Darstellung  eines neuen     Aminoketons,    dadurch gekenn  zeichnet, dass man     p-Chlorlaurophenon    mit       Dimethylamin    und das entstandene     p-Dime-          thylaminolaurophenon    mit     Diäthylsulfat    um  setzt.

   Die neue Verbindung, das     p-Dimethyl-          äthylammoniumlaurophenon-ätbylsulfat,    eine       bräunliche,    dickflüssige Masse, ist in Wasser  klar löslich und eignet sich als Netzmittel,  als Mittel zur Verbesserung der Wasserecht  heit von Direktfärbungen, als Abziehmittel  für     Naphtol-AS-Färbungen,    als Mottenschutz  mittel und besitzt gute     fungizide    und bak  terizide Eigenschaften.  



  <I>Beispiel:</I>  250 Teile Chlorbenzol werden mit 100  Teilen Aluminiumchlorid versetzt und unter  Rühren 109 Teile     Palmkernfettsäurechlorid          zugetropft.    Nach 15 Stunden bei<B>70-800</B>  wird abgekühlt, in Wasser gegossen und mit  Wasserdampf destilliert, bis alles über  schüssige Chlorbenzol verschwunden ist. Zu-    rück bleiben 100 Teile     p-Chlorlaurophenon     vom     Kp15    = 195-230<B>0</B> C.  



  50 Teile dieser Verbindung werden mit  einer alkoholischen Lösung von 40 Teilen       Dirnethylamin    in 250     Volumteilen    Alkohol  und etwas Kupferpulver im     Autoklaven    20  Stunden auf 220-230   erhitzt. Nach Ent  fernen des Kupferpulvers und Verjagen des  Lösungsmittels lässt sich das     p-Dimethyl-          aminolaurophenon    als gelbes Ö1 gewinnen,  das langsam erstarrt. Es ist in Salzsäure  klar löslich.     Kp1s    = 225-250   C.  



  20 Teile     p-Dimethylaminolaurophenon    und  15 Teile     Diäthylsulfat    werden während 30  Minuten auf 120-130   erhitzt. Es bildet  sich das klar wasserlösliche     p-Dimethyläthyl-          ammoniumlaurophenon-äthylsulfat    in Form  einer bräunlichen, dickflüssigen Masse.



  Process for the preparation of a new aminoketone. The subject of the present Zusatzpa tentes is a process for the preparation of a new aminoketone, characterized in that p-Chlorlaurophenon with dimethylamine and the resulting p-Dimethylaminolaurophenon with diethyl sulfate is.

   The new compound, p-Dimethyl- äthylammoniumlaurophenon-ätbylsulfat, a brownish, viscous 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 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 <B> 70-800 </B> the mixture is cooled, poured into water and distilled with steam until all excess chlorobenzene has disappeared. What remains are 100 parts of p-chlorophenone with a bp15 = 195-230 <B> 0 </B> C.



  50 parts of this compound are heated to 220-230 for 20 hours 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 chasing off the solvent, the p-dimethylaminolaurophenone can be obtained as a yellow oil that slowly solidifies. It is clearly soluble in hydrochloric acid. Kp1s = 225-250 C.



  20 parts of p-dimethylaminolaurophenone and 15 parts of diethyl sulfate are heated to 120-130 for 30 minutes. The clear, water-soluble p-dimethylethylammoniumlaurophenone ethyl sulfate is formed in the form of a brownish, viscous mass.
