Description

  

  Verfahren zur Darstellung eines     Küpenfarbstoffes    der     Anthrachinonreilie.       Durch das Hauptpatent ist ein Verfahren  zur Darstellung eines     Küpenfarbstoffes    der       Anthrachinonreille    geschützt, dadurch ge  kennzeichnet,     dass    man<B>1</B>     Mol        Naphthalin-          2.        6-diearbonsäuredihalogenicl    mit 2     Mol        a-          Aminoanthrachinon    kondensiert.  



  Es wurde gefunden,     dass    man zu einem  sehr wertvollen Farbstoff gelangt, wenn man  <B>1</B>     M.ol        p-Terphenyldiearbonsäuredihalogenid     der Formel  
EMI0001.0016     
    mit     --)        Mol        a-Aminoanthrachinon    kondensiert.  Der neue Farbstoff besitzt hervorragende       Echtheitseigens,chaften    und zeichnet sich vor  dem Farbstoff des Hauptpatentes über  raschenderweise durch grössere     Faseraffinitkt     aus.  



  Die Kondensation des     p-Terphenyldiear-          bonsäuredihalo,(renids    mit dem     a-Amino-          anthrachinon    wird zweckmässig in einem    höher siedenden Lösungsmittel bei Gegen  wart oder Abwesenheit säurebindender Mittel  ausgeführt. Die     Halogenid-,    insbesondere       Chloridbildung    und die Kondensation zu den  Farbstoffen kann in einer Phase durch  geführt werden.

      <I>Beispiel:</I>  <B>30 kg</B>     p-Terphenyldiearbonsäure     
EMI0001.0029     
         ,verden,    in etwa<B>500 kg</B>     Dichlorbenzol    mit  <B>35 kg</B>     Thionylehlorid    so lange zum Sieden  erhitzt, bis völlige Lösung eingetreten ist.  Dann destilliert man zweckmässig das über  schüssige     Thionylehlorid    ab, gibt 46<B>k '</B>     -          a-Amilioanthrachinon    zu und erhitzt etwa  2 Stunden zum Sieden, bis die     Salzsäureent-          wicklung    zum Stillstand gekommen ist.

   Der  in gelben Kristallen abgeschiedene Farbstoff  wird heiss     abfiltriert    und mit Sprit aus-      gewaschen. Er färbt aus     bordeauxrater    hei       sser    und kalter     Küpe    ein klares und kräftige!       grünstichiges    Gelb von hervorragenden Echt       heitseigenschaften    und<B>.</B> sehr     gut-er    Faser       affinität.  



  Process for the preparation of a vat dye of the anthraquinone line. The main patent protects a process for the preparation of a vat dye of the anthraquinone ring, characterized in that <B> 1 </B> mol naphthalene-2,6-diacid dihalogenicl is condensed with 2 mol of a-aminoanthraquinone.



  It has been found that a very valuable dye is obtained if one uses <B> 1 </B> M.ol p-terphenyldiearboxylic acid dihalide of the formula
EMI0001.0016
    condensed with -) moles of a-aminoanthraquinone. The new dye has excellent fastness properties, properties and surprisingly stands out from the dye of the main patent by a greater fiber affinity.



  The condensation of the p-terphenyldiacid dihalo, (renide with the a-aminoanthraquinone is expediently carried out in a higher-boiling solvent in the presence or absence of acid-binding agents be performed.

      <I> Example: </I> <B> 30 kg </B> p-terphenyldiacid
EMI0001.0029
         , verden, about <B> 500 kg </B> dichlorobenzene with <B> 35 kg </B> thionyl chloride heated to the boil until complete dissolution occurs. The excess thionyl chloride is then expediently distilled off, 46 a-amilioanthraquinone is added and the mixture is heated to the boil for about 2 hours until the development of hydrochloric acid has come to a standstill.

   The dye deposited in yellow crystals is filtered off while hot and washed out with gasoline. It turns the burgundy rater hot and cold vat into a clear and strong one! Greenish yellow with excellent fastness properties and <B>. </B> very good fiber affinity.
