Description

  

  Verfahren zur Herstellung eines     Anthrachinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man     1,5-          Diaminoanthrachinon,        o-Chlorbenzaldehyd    und       Anieisensänre    aufeinander einwirken lässt.  Das so erhaltene     Anthrachinonderivat    stellt  feine, bronzeglänzende Kristalle dar. Es     Mist     sieh in organischen Lösungsmitteln wie Ben  zol,     Nitrobenzol,        Eisessig        etc.    mit violett  roter Farbe.

   Es ist ein wertvolles Zwischen  produkt für die Herstellung weiterer     Farbstoffe.     <I>Beispiel:</I>       a    Teile     1,5-D1ainlnoanthi-aelilnon    werden  mit     50    Teilen     o-Chlorbenzaldehvd    und  3     Teilen    85     oioiger    Ameisensäure so lange  unter gutem Rühren auf     Wasserbadtenipera-          tur    gehalten, bis die     Reaktion    beendet, das  heisst keine weitere Verschiebung der Farbe    der Schmelze nach     violettrot    mehr zu beob  achten ist.

   Beim Erkalten scheidet     sich    das       o-Chlorbenzylderivat    aus.



  Process for the production of an anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained if 1,5-diaminoanthraquinone, o-chlorobenzaldehyde and aniseed iron are allowed to act on one another. The anthraquinone derivative obtained in this way is fine, bronze-shining crystals. It crap looks in organic solvents such as benzene, nitrobenzene, glacial acetic acid, etc. with a purple-red color.

   It is a valuable intermediate for the manufacture of other dyes. <I> Example: </I> a parts of 1,5-D1ainlnoanthi-aelilnon are kept with 50 parts of o-chlorobenzaldehyde and 3 parts of 85% formic acid with thorough stirring at water bath temperature until the reaction has ended, that is, none a further shift in the color of the melt towards violet-red can be observed.

   The o-chlorobenzyl derivative separates out when it cools.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Anthrachinonderivates, dadurch gekennzeieh- net, dass man 1,5-Diaminoaiithrachinon, o Chlorbenzaldehyd und Ameisensäure aufein ander einwirken lässt. Das so erhaltene Anthrachinonderivat stellt feire, bronzeglän zende Kristalle dar. Es löst sich in organi schen Lösungsmitteln wie Benzol, Nitrobenzol, Eisessig etc. mit violettroter Farbe. Es ist ein wertvolles Zwischenprodukt für die Her stellung weiterer Farbstoife. PATENT CLAIM: Process for the production of a new anthraquinone derivative, characterized in that 1,5-diaminoalithraquinone, chlorobenzaldehyde and formic acid are allowed to act on one another. The anthraquinone derivative obtained in this way is fiery, shiny bronze crystals. It dissolves in organic solvents such as benzene, nitrobenzene, glacial acetic acid, etc. with a purple-red color. It is a valuable intermediate for the manufacture of other colorants.
