Description

  

  Verfahren zur Herstellung von     4'-Ogyphenyl-2-aminochrysen.       Gemäss dem im Hauptpatent beschrie  benen Verfahren erhält man das     V-Ogy-          phenyl-3-aminopyren,    wenn man     3-Ogypyren     mit     1-Ogy-4-aminobenzol    in Gegenwart     vors          Bisulfitlauge    bei     Temperaturen    von etwa       130    bis<B>170'</B> C kondensiert.  



  Gegenstand des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    von     4'-Ogy-          phenyl-2-aminochrysen,    welches dadurch ge  kennzeichnet ist, dass man 2-     Aminochrysen     mit     1-Ogy-4-aminobenzol    in Gegenwart von       Bisulfitlauge    auf     Temperaturen    von etwa  130 bis<B>170'</B> C und in Gegenwart eines  erheblichen     Überschusses        des    genannten       Aminophenols    erhitzt.

      <I>Beispiel:</I>  12 Teile     2-Aminochrysen    werden mit 25  Teilen     1-Ogy-4-aminobenzol,        @6        Teilen    Na  triumsulfit und 100     Volumteilen        Bisulfit-          la.uge    von<B>38'</B>     B6    60     Stunden    auf 130 bis    140" erhitzt.

   Das erhaltene Kondensations  produkt wird abgesaugt, mit heissem Wasser       gewaschen    und durch     Umlösen    aus verdünn  ter Natronlauge unter Zusatz von     etwas        Hy-          drosulfit        gereinigt.    Die neue Verbindung  lässt sich aus dieser Lösung     mit        Bisulfit     fällen. Das Endprodukt ist identisch mit dem  nach     dem    Zusatzpatent Nr. 191417 erhält  lichen Produkt.



  Process for the preparation of 4'-ogyphenyl-2-aminochrysen. According to the process described in the main patent, V-ogyphenyl-3-aminopyrene is obtained if 3-ogypyrene is mixed with 1-ogy-4-aminobenzene in the presence of bisulfite liquor at temperatures of about 130 to 170 '</ B> C condensed.



  The present patent is a process for the preparation of 4'-Ogy-phenyl-2-aminochrysen, which is characterized in that 2-aminochrysen with 1-Ogy-4-aminobenzene in the presence of bisulfite liquor at temperatures of about 130 to <B> 170 '</B> C and heated in the presence of a considerable excess of said aminophenol.

      <I> Example: </I> 12 parts of 2-aminochrysene are mixed with 25 parts of 1-ogy-4-aminobenzene, 6 parts of sodium sulfite and 100 parts by volume of bisulfite la.uge of <B> 38 '</B> B6 Heated to 130 to 140 "for 60 hours.

   The condensation product obtained is filtered off with suction, washed with hot water and purified by dissolving from dilute sodium hydroxide solution with the addition of a little hydrosulfite. The new compound can be precipitated from this solution with bisulfite. The end product is identical to the product obtainable according to additional patent no.
