Description

  

  Verfahren zur Darstellung eines Kondensationsproduktes der     Anthrachinonreihe.            Tie    im Hauptpatent angegeben ist, kön  nen Kondensationsprodukte der     Anthrachinon-          reihe        .dadurch    erhalten werden, dass man       Phthaloylehinazoline,    welche in dem ange  gliederten     heterocyclis-chen        Ring        wenigstens     ein an ein     Kohlenstoffatom    gebundenes  Halogenatom enthalten, mit Aminen     umsetzt,

            welche        mindestens        nach        ein        austausehbares          Wasserstoffatom    besitzen.  



  Gegenstand des vorliegenden Patente ist  nun     ein    Verfahren zur     Darstellung    eines       Kondensationsproduktes    der     Anthrachinon-          reihe,    dadurch     gekennzeichnet,        dass    man 1  Mal 2 .     4-Dihalogen-7    .

       8-phthaloylchinazolin          mit    2     Mol        1-Aminoanthrachinon    zur Um  setzung     bringt.    Vorzugsweise verwendet man  als     Halogenverbindung    die     entsprechende          Chlorverbinidung.    Die Halogenatome     sind     leicht beweglich,     so,dass    die Umsetzung mit  dem Amin ohne     Schwierigkeiten    erfolgt.

   Man  arbeitet zweckmässig in     Gegenwart        eines    in  differenten     Lösemittels    wie     Nitrobenzol,    Tri-         chlorbenzol        oder    Phenol bei erhöhten Tempe  raturen.  



  Der erhaltene neue Farbstoff     ist    in     or-          ganisehen    Lösemitteln praktisch unlöslich. Er       v,erküpt    mit rotbrauner Farbe und     liefert    .auf  Baumwolle orange Färbungen.

      <I>Beispiel:</I>         Durch        Einwirkung    von überschüssigem       Ogalychlorid    auf eine     nitrotbenzolisehe    Sus  pension des     1-Aminoanthrachinan-2@-carb,

Alsdann  saugt man das     Reaktionsprodukt    bei     12#0'    C  ab,

   verrührt den     noch        feuchten        Nubseh-          kuchen    mehrmals mit     heissem        Nitrobenzol     und     trocknet        nach    Entfernung der     Mutter-          lauge    im     Vakuum    bei 130   C.

   Der in or  ganischen     Lösemitteln        praktisch        unlösliche     Farbstoff     verküpt    mit     rotbrauner    Farbe und       liefert    auf Baumwolle     orange        Färbungen.  



  Process for the preparation of a condensation product of the anthraquinone series. As stated in the main patent, condensation products of the anthraquinone series can be obtained by reacting phthaloylehinazolines, which in the attached heterocyclic ring contain at least one halogen atom bonded to a carbon atom, with amines,

            which have at least one exchangeable hydrogen atom.



  The subject of the present patent is a process for the preparation of a condensation product of the anthraquinone series, characterized in that one time 2. 4-dihalo-7.

       8-phthaloylquinazoline with 2 moles of 1-aminoanthraquinone to implement. The corresponding chlorine compound is preferably used as the halogen compound. The halogen atoms are easily mobile, so that the reaction with the amine takes place without difficulty.

   It is expedient to work in the presence of a different solvent such as nitrobenzene, trichlorobenzene or phenol at elevated temperatures.



  The new dye obtained is practically insoluble in organic solvents. He v, küpt with red-brown color and provides orange dyeings on cotton.

      <I> Example: </I> By the action of excess ogalychloride on a nitrotbenzolisehe suspension of 1-aminoanthraquinane-2 @ -carb,

  On-amids, the following diogychinazoline is obtained with a violent reaction
EMI0001.0056
           which represents yellow leaflets dissolved from pyridine. When heated with phosphorus oxychloride-phosphorus pentachloride in nitrobenzene, it converts into 2-4-dichloro-7.

       8-phthaloyl-quinazoline about.



  5 parts by weight of 1-aminoanthraquinone and 3.3 parts by weight of 2,4-dichloro-7.8-phthaloyl-quinazoline are heated in 1'50 parts by weight of nitrobenzene to 210 ° C. to stop the elimination of chlorine.%. The reaction product is then suctioned off at 12 ° C,

   stir the still moist Nubseh cake several times with hot nitrobenzene and dry after removing the mother liquor in a vacuum at 130 C.

   The dye, which is practically insoluble in organic solvents, vets with a red-brown color and produces orange colorations on cotton.
