Description

  

  Verfahren zur Herstellung eines     Küpenfarhstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man     4-Aminoanthrachinon-2,1.-        (N)-1',2'-(N)-          ben7aeridon    mit einem     3,4-dibrombenzoylie-          renden    Mittel behandelt.  



  Der neue Farbstoff bildet blaue Kristalle  und färbt pflanzliche Fasern aus violetter       Hydrosulfitküpe    in blauen Tönen von guter  Echtheit.  



  Als     3,4-dibrombenzoylierende    Mittel kön  nen     gemäss    vorliegendem Verfahren beispiels  weise     3,4-1)ibrombenzoesäure    und insbesondere  ihre funktionellen Derivate, vorzugsweise     3,4-          Dibromhenzoylehlorid,    verwendet werden. Die  Reaktion wird in an sieh bekannter Weise       zweekmässia    in einem indifferenten Lösungs  mittel, wie Nitrobenzol,     Tri-    oder     Diehlor-          benzol,        durchgeführt.     



  <I>Beispiel:</I>  4,2 Teile     3,4-Dibrombenzoesäure    werden  mit     70-1    Teilen     o-Diehlorbenzol,    das ein wenig       Pyridin    enthält, verrührt. Man. setzt dem     Ge-          miseh    8 Teile     Thionylehlorid    zu und erhitzt  unter     Rüekfluss    allmählich bis zum Sieden.

    Sobald die Bildung des Säurechlorids beendet  ist, destilliert man das überschüssige     Thionyl-          ehlorid    mit etwas Lösungsmittel ab und gibt  der     Lösung    nach dem Abkühlen auf etwa 00     3,4 Teile     4-Aminoanthrachinon-2,1-        (N)-1',2'-          (N)-benzaeridon    zu. Darauf lässt man 1     Stunde     bei 7.30 bis 7.40  rühren, nachher abkühlen  und filtriert den Farbstoff ab.



  Process for the production of a vat raw material. It has been found that a valuable vat dye can be produced by treating 4-aminoanthraquinone-2,1.- (N) -1 ', 2' - (N) -ben7aeridone with a 3,4-dibromobenzoyling agent.



  The new dye forms blue crystals and dyes vegetable fibers from purple hydrosulfite vat in blue shades of good fastness.



  3,4-dibromobenzoylating agents which can be used according to the present process are, for example, 3,4-1) ibromobenzoic acid and, in particular, its functional derivatives, preferably 3,4-dibromohenzoylechloride. The reaction is carried out in a manner known per se in an inert solvent such as nitrobenzene, tri- or diehlorbenzene.



  <I> Example: </I> 4.2 parts of 3,4-dibromobenzoic acid are mixed with 70-1 parts of o-dichlorobenzene, which contains a little pyridine. Man. add 8 parts of thionyl chloride to the mixture and gradually heat it to boiling under reflux.

    As soon as the formation of the acid chloride has ended, the excess thionyl chloride is distilled off with a little solvent and, after cooling to about 00, 3.4 parts of 4-aminoanthraquinone-2,1- (N) -1 ', 2' are added to the solution. - (N) -benzaeridone too. The mixture is then stirred for 1 hour at 7.30 am to 7.40 am, then cooled and the dye is filtered off.
