Description

  

  Verfahren zur Darstellung eines     Arylaminonaphtalinderivates.       Analog dem im Hauptpatent beschriebenen  Verfahren kann man     1.5-Di-(4'-oxyphenyl-          amino)-naphtalin    darstellen, wenn man 1.5  Diaminonaphtalin und     4-Amino-l-oxybenzol     mit     Bisulfitlauge    im     offenen    oder im Druck  gefäss durch Erhitzen kondensiert.  



  <I>Beispiel:</I>  <B>158</B> Teile     1.5-Diaminonaphtalin    werden  in einem verbleiten     Rührkessel    mit einer  Lösung von 400 Teilen     Alkalibisulfit    in 3000  Teilen Wasser und 260 Teilen     4-Amino-l-          ogybenzol    unter Druck und Rühren etwa  36 Stunden auf 115-120   C erhitzt. Die  Aufarbeitung erfolgt wie im Beispiel des  Zusatzpatentes Nr.     135646    beschrieben. Das  Endprodukt ist identisch mit dem dort er  haltenen.



  Process for the preparation of an arylaminonaphthalene derivative. 1.5-Di- (4'-oxyphenyl-amino) -naphthalene can be prepared analogously to the process described in the main patent if 1.5-diaminonaphthalene and 4-amino-1-oxybenzene are condensed with bisulfite lye in an open or in a pressure vessel by heating.



  <I> Example: </I> <B> 158 </B> parts of 1,5-diaminonaphthalene are in a leaded stirred tank with a solution of 400 parts of alkali bisulfite in 3000 parts of water and 260 parts of 4-amino-l-ogybenzene under pressure and Stirring heated to 115-120 ° C. for about 36 hours. Working up is carried out as described in the example of additional patent no. 135646. The end product is identical to the one received there.
