Description

  

  Verfahren zur Herstellung eines sekundären     Alkylamins.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     sekundären          Alky        lamins,    dadurch gekennzeichnet, dass  man     Tetradecylchlorid    mit wässerigem Am  moniak im Druckkessel auf Temperaturen  zwischen 120 und 170   erhitzt.  



  Das so erhaltene     Ditetradecylamin    kri  stallisiert aus Alkohol in farblosen Kristal  len, die bei 61   schmelzen. Das Chlorhydrat  ist in Wasser unlöslich. Das neue Amin soll  als Zwischenprodukt zur Herstellung von       Färbereihilfsprodukten    Verwendung finden.  <I>.Beispiel:</I>  50 kg     Tetradecylchlorid    werden mit  400 kg etwa 55 bis 60%igem wässerigem  Ammoniak 7 bis 8 :Stunden auf 140 bis 145    im Druckkessel erhitzt. Nach Erkalten wird  das feste Reaktionsprodukt von der wässeri-    gen Schicht getrennt und getrocknet. Das  Umsetzungsprodukt besteht vornehmlich aus       Ditetradecylamin,    das durch     Umkristallisie-          ren    aus Alkohol gereinigt werden kann.



  Process for the preparation of a secondary alkylamine. The present patent relates to a process for the production of a secondary alkylamine, characterized in that tetradecyl chloride is heated to temperatures between 120 and 170 in a pressure vessel with aqueous ammonia.



  The ditetradecylamine obtained in this way crystallizes from alcohol in colorless crystals which melt at 61. The chlorine hydrate is insoluble in water. The new amine is said to be used as an intermediate in the manufacture of auxiliary dye products. <I>. Example: </I> 50 kg of tetradecyl chloride are heated with 400 kg of about 55 to 60% aqueous ammonia for 7 to 8 hours to 140 to 145 hours in a pressure vessel. After cooling, the solid reaction product is separated from the aqueous layer and dried. The reaction product consists primarily of ditetradecylamine, which can be purified by recrystallization from alcohol.
