Description

  

  Verfahren zur Herstellung eines     stickstoffhaltigen        Naphthalinderivates.       Es wurde gefunden, dass     ein        stickstoff-          haltiges        Naphthalinderivat    hergestellt werden  kann, wenn man 1     Mol        2,6-Dihalogennaph-          thalin    mit 2     Mol        5-Amino-1,9-anthrapyri-          midin    umsetzt.  



  Das neue Produkt ist ein schwarzblaues       kristallines    Pulver, das sich     in    konzentrier  ter Schwefelsäure mit gelbgrüner Farbe löst,  bei 460   noch nicht schmilzt     und    Baumwolle  aus gelbbrauner     Küpe    blau färbt. Es stellt  überdies ein wertvolles Zwischenprodukt für  die Herstellung von     Küpenfarbstoffen    dar.  



  Als     2,6-Dihalogennaphthalin    kann bei  spielsweise     2,6-Dibromnaphthalin    verwendet  werden.  



  Die Umsetzung wird vorteilhaft durch       Erhitzen    der Komponenten     in        Lösungs-    oder  Verdünnungsmitteln, wie z. B.     Amylalkohol,     Nitrobenzol oder Naphthalin, und zweck  mässig in     Anwesenheit    von Katalysatoren,  wie Kupfer oder     Kupferverbindungen,    sowie  von säurebindenden Mitteln, durchgeführt.

           entwässertes        Natriumacetat,    3 Teile wasser  freies     Natriumcarbonat    und 0,26 Teile     Kup-          ferchlorür    werden während 24     Stunden    unter  Rühren in 90 Teilen trockenem     Nitrobenzol     zum Sieden erhitzt. Nun wird heiss     filtriert     und der Rückstand mit     Nitrobenzol,    Benzol  und Alkohol gewaschen, mit     verdünnter     Säure ausgekocht,     filtriert,    gewaschen und  getrocknet.

      <I>Beispiel:</I>  2,86 Teile     2,6-Dibromnaphthalin,    5,43  Teile     5-Amino-1,9-anthrapyrimidin,    3 Teile



  Process for the production of a nitrogen-containing naphthalene derivative. It has been found that a nitrogen-containing naphthalene derivative can be produced if 1 mole of 2,6-dihalo-naphthalene is reacted with 2 moles of 5-amino-1,9-anthrapyrimidine.



  The new product is a black-blue crystalline powder that dissolves in concentrated sulfuric acid with a yellow-green color, does not yet melt at 460 and dyes cotton from a yellow-brown vat blue. It is also a valuable intermediate product for the manufacture of vat dyes.



  2,6-Dibromonaphthalene, for example, can be used as 2,6-dihalonaphthalene.



  The reaction is advantageous by heating the components in solvents or diluents, such as. B. amyl alcohol, nitrobenzene or naphthalene, and conveniently carried out in the presence of catalysts such as copper or copper compounds, and acid-binding agents.

           Dehydrated sodium acetate, 3 parts of anhydrous sodium carbonate and 0.26 part of copper chloride are heated to boiling in 90 parts of dry nitrobenzene for 24 hours while stirring. It is then filtered while hot and the residue is washed with nitrobenzene, benzene and alcohol, boiled with dilute acid, filtered, washed and dried.

      <I> Example: </I> 2.86 parts of 2,6-dibromonaphthalene, 5.43 parts of 5-amino-1,9-anthrapyrimidine, 3 parts
