Description

  

      \'erfahren    zur Darstellung eines     Arylaininonaphtalinderivates.       Analog dem im Hauptpatent beschriebenen  Verfahren kann 1     -(4'-Oxyphenyl)-atninonaph-          talin    dargestellt werden, wenn man     1-Amino-          naplitalin    und     4-Amitio-l-oxybeiizol    mit     Bi-          stilfitlauge    im     offenen    oder im Druckgefäss  durch erhitzen kondensiert.  



  <I>Beispiel:</I>  144 Teile     1-Aminonaphtalin    und 160  Teile     4-Amino-l-oxybenzol    werden mit 4000  Teilen einer     Natriumbisulfitlösung    von 20       B6     in einem geschlossenen emaillierten     Rühr-          kessel    bei einer Temperatur von 112-115   C  zirka 40 Stunden lang gerührt. Die Auf  arbeitung erfolgt wie im Beispiel des Zusatz  patentes     Nr:    135642 beschrieben; das End  produkt ist mit dem gemäss dieses Zusatz  patentes erhaltenen identisch.



      \ 'Learned about the preparation of an arylaininonaphthalene derivative. Analogous to the process described in the main patent, 1- (4'-oxyphenyl) -atninonaphthalene can be prepared if 1-aminonaplitaline and 4-amitio-1-oxybeiizole are condensed by heating with bisstile liquor in an open or in a pressure vessel.



  <I> Example: </I> 144 parts of 1-aminonaphthalene and 160 parts of 4-amino-1-oxybenzene are mixed with 4000 parts of a sodium bisulfite solution of 20 B6 in a closed enamelled stirred kettle at a temperature of 112-115 C for about 40 Stirred for hours. The processing is carried out as described in the example of the additional patent no: 135642; the end product is identical to the one obtained according to this additional patent.
