Description

  

  Verfahren zur Darstellung eines     Aralkylamins.       Es wurde gefunden, dass man nach dem  im Hauptpatent beschriebenen Verfahren       9.10-Di(oo-aminomethyl)-anthracen    herstellen  kann, wenn man an Stelle des dort verwen  deten Benzols     Anthracen    und eine entspre  chende Menge     m-Chlormethylphtalimid    ver  wendet.  



  <I>.</I>     Reispiel:     89 Teile     Anthracen    werden mit 195 Teilen       w-Chlor-methylphtalimid    und 10 Teilen als Ka  talysator dienendem Chlorzink, in Nitrobenzol  gelöst, auf 85-100   C erhitzt. 146 Teile des  Reaktionsproduktes werden in 10Ö0 Teilen  Alkohol, 400 Teilen Wasser und 83 Teilen       Natriumhydrogydlösung    von 35       B6    heiss ge  löst und mit 200 Teilen Salzsäure von 12       B6    gespalten.

   Man scheidet die     Phtalsäure     ab, versetzt die- Lösung mit überschüssigem       Natriumhydrogyd    und schüttelt das     9.10-Di-          (c)-aminomethyl)-anthracen    mit Benzol aus.  



  Das     9.10-Di(co-aminomethyl)-anthrazen    bil  det hellgelbe Kristalle, die in Wasser schwer  löslich sind und sich zwischen 250-270    zersetzen. Das     Dichlorhydrat    löst sich leicht    in Wasser. Verwendung soll die Verbindung  finden bei der Darstellung von Farbstoffen.



  Process for the preparation of an aralkylamine. It has been found that 9.10-di (oo-aminomethyl) anthracene can be produced by the process described in the main patent if anthracene and an appropriate amount of m-chloromethylphthalimide are used instead of the benzene used there.



  Example: 89 parts of anthracene are dissolved in nitrobenzene and heated to 85-100 ° C. with 195 parts of w-chloro-methylphthalimide and 10 parts of zinc chloride, which serves as a catalyst. 146 parts of the reaction product are dissolved hot ge in 10Ö0 parts of alcohol, 400 parts of water and 83 parts of sodium hydrogen hydroxide solution of 35 B6 and split with 200 parts of hydrochloric acid of 12 B6.

   The phthalic acid is separated off, excess sodium hydrogen is added to the solution and the 9.10-di- (c) -aminomethyl) -anthracene is extracted with benzene.



  The 9.10-di (co-aminomethyl) -anthracene forms pale yellow crystals that are sparingly soluble in water and decompose between 250-270. The dichlorohydrate dissolves easily in water. The compound is intended to be used in the representation of dyes.
