Description

  

  Verfahren zur Herstellung eines     Karbazolderivates.       Es wurde gefunden, dass ein     Karbazol-          derivat    erhalten werden kann, wenn man die  Verbindung der Formel  
EMI0001.0004     
    mit dianotierenden Mitteln behandelt und  das entstandene Produkt hierauf auf höhere  Temperatur erhitzt.  



  Das     Karbazolderivat    der Formel  
EMI0001.0006     
    stellt ein wertvolles Zwischenprodukt zur  Herstellung von Farbstoffen dar. Es bildet  orange gefärbte' Kristalle, die sich in kon  zentrierter Schwefelsäure mit blauer Farbe  lösen und die in organischen Lösungsmitteln  schwer löslich sind.  



  Das     Karbazolderivat    wird besonders glatt  erhalten, wenn das Erhitzen auf höhere Tem  peratur in Gegenwart eines organischen  Lösungsmittels, wie zum Beispiel Nitrobenzol  oder Chlornaphthalin, sowie in Gegenwart  einer organischen Base, wie. zum Beispiel       Dimethylanilin,        Diäthylanilin    oder     Diphenyl-          amin    erfolgt.  



       Beispiel:     120 Gewichtsteile     o'-Nitranilinoarithra-          chinon,    das man zum Beispiel durch Um  setzung von     1-Aminoarithrachinon    mit     o-Nitro-          chlorbenzol    nach     Ullmann    und     Fodor    dar  stellen kann (siehe A. 380, 327), werden 'mit  wenig Sprit     angeteigt,    hierauf mit 2000 Ge-           wichtsteile    Wasser von etwa 60 o versetzt.  Unter Rühren gibt man nun 800 Gewichts  teile 30     %ige    Natronlauge zu und streut so  dann 360 Gewichtsteile     Natriumhydrosulfit     ein.

   Man hält     1/2    Stunde bei<B>50</B> bis 60 o und  oxydiert hierauf mit Luft. Die so dargestellte       o'-Aminoanilinoverbindung    wird nun mit  2000 Gewichtsteilen Wasser angerührt, mit  100 Gewichtsteilen konzentrierter technischer  Salzsäure versetzt und einige Zeit verrührt,  dann wird mit Eis gekühlt und eine Natrium  nitritlösung entsprechend einem Gehalt von  30 Gewichtsteilen     Natriumnitrit    langsam  zugegeben. Man erhitzt hierauf zum Sieden  und filtriert. 50 Gewichtsteile der so erhal  tenen     Aziminoverbindung    werden nun mit  250 Gewichtsteilen Nitrobenzol und 50 Ge  wichtsteilen     Diäthylanilin    solange zum Sieden  erhitzt, bis das Ausgangsmaterial verschwun  den ist.

   Beim Abkühlen kristallisiert das       1.2-Phthaloylkarbazol    aus.



  Process for the production of a carbazole derivative. It has been found that a carbazole derivative can be obtained when using the compound of the formula
EMI0001.0004
    treated with dianotizing agents and the resulting product then heated to a higher temperature.



  The carbazole derivative of the formula
EMI0001.0006
    is a valuable intermediate product for the production of dyes. It forms orange colored crystals which dissolve in concentrated sulfuric acid with a blue color and which are sparingly soluble in organic solvents.



  The carbazole derivative is obtained particularly smoothly when the heating to higher Tem temperature in the presence of an organic solvent such as nitrobenzene or chloronaphthalene, as well as in the presence of an organic base such as. for example dimethylaniline, diethylaniline or diphenylamine takes place.



       Example: 120 parts by weight of o'-nitroanilinoarithrachinone, which can be made into a paste with a little fuel, for example by reacting 1-aminoarithraquinone with o-nitrochlorobenzene according to Ullmann and Fodor (see A. 380, 327) , then mixed with 2000 parts by weight of water at about 60 o. 800 parts by weight of 30% sodium hydroxide solution are then added with stirring, and 360 parts by weight of sodium hydrosulfite are then sprinkled in.

   It is held at <B> 50 </B> to 60 o for 1/2 hour and then oxidized with air. The o'-aminoanilino compound thus prepared is now mixed with 2000 parts by weight of water, 100 parts by weight of concentrated technical hydrochloric acid are added and the mixture is stirred for some time, then it is cooled with ice and a sodium nitrite solution corresponding to 30 parts by weight of sodium nitrite is slowly added. It is then heated to the boil and filtered. 50 parts by weight of the azimino compound obtained in this way are then heated to boiling with 250 parts by weight of nitrobenzene and 50 parts by weight of diethylaniline until the starting material has disappeared.

   The 1,2-phthaloyl carbazole crystallizes out on cooling.
