Description

  

      Verfahren    zur Darstellung eines Kondensationsproduktes der     Anthrachinonreihe.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines neuen Kondensationspro  duktes der     Anthrachinonreihe    beschrieben,       das    dadurch gekennzeichnet ist, dass man auf       2-Halogenchinizariri    Phenol einwirken lässt,  und das so erhältliche     2-Phenoxychinizarin     mit einem stilfierenden Mittel bis zur     Auf-          iiahnie    von     2-Sulfogruppen    behandelt.  



  Gegenstand vorliegenden Patentes ist nun  ein Verfahren zur Darstellung eines Konden  sationsproduktes der     Anthrachinonreihe,    da  durch gekennzeichnet, dass man     2-Halogen-          chinizarin    mit Phenol umsetzt und das so  erhältliche     2-Pherioxychinizai in    mit einem       stilfierenden    Mittel bis zur Aufnahme einer       Sulfogruppe    behandelt.  



  Die so erhaltene     2-Phenoxychinizai-in-Mono-          sulfosäure    soll insbesondere für die Herstel  lung von     Farblacken    Verwendung finden.  <I>Beispiel:</I>  15 Gewichtsteile     2-Bromcliinizarin,    7,5 Ge  wichtsteile     Natriumphenolat    und 0,4 Gewichts-    teile Kupferacetat werden in 150 Gewichts  teilen Phenol unter     Rühren    zum Sieden er  hitzt. Die anfänglich violett gefärbte dicke  Schmelze wird allmählich orangefarben und       dünnflüssig.    Sobald unverändertes Ausgangs  material nicht mehr nachzuweisen ist, wird  abgekühlt und bei 70   C mit 300 Gewichts  teilen Methanol verdünnt.

   Das in schönen  orangeroten     Nädelchen    ausgefallene     2-Phe-          noxychinizarin    wird bei Raumtemperatur ab  gesaugt, ausgewaschen und getrocknet. Es  kristallisiert aus Eisessig oder     p-Chlortoluol     in prachtvollen orangeroten Nadeln, die bei  <B>209-2110</B> schmelzen.  



  Das so erhaltene     2-Phenoxychinizarin    wird       sulfiert    durch Auflösung in der zehnfachen  Menge einer Schwefelsäure, die zirka 2     0/0     freies     SOs    enthält. Isolierung der gebilde  ten     Sulfosäure    wie üblich als     Natriumsalz,     das in Wasser löslich ist. Die Lösung der       Sulfosäure    in starker Schwefelsäure ist blau  stichig rot.



      Process for the preparation of a condensation product of the anthraquinone series. In the main patent, a process for the preparation of a new condensation product of the anthraquinone series is described, which is characterized in that phenol is allowed to act on 2-haloquinizarin, and the 2-phenoxyquinizarin thus obtainable with a styling agent up to the dissolution of 2-sulfo groups treated.



  The subject of the present patent is a process for the preparation of a condensation product of the anthraquinone series, characterized in that 2-haloquinizarin is reacted with phenol and the thus obtainable 2-pherioxychinizai is treated with a styling agent until a sulfo group is taken up.



  The 2-phenoxyquinizai-in-monosulfonic acid obtained in this way is said to be used in particular for the manufacture of colored lacquers. <I> Example: </I> 15 parts by weight of 2-bromoclinizarin, 7.5 parts by weight of sodium phenolate and 0.4 parts by weight of copper acetate are heated to boiling in 150 parts by weight of phenol with stirring. The thick melt, initially purple in color, gradually turns orange and runny. As soon as unchanged starting material can no longer be detected, the mixture is cooled and diluted at 70 C with 300 parts by weight of methanol.

   The 2-phenoxyquinizarin, which has precipitated in beautiful orange-red needles, is sucked off, washed out and dried at room temperature. It crystallizes from glacial acetic acid or p-chlorotoluene in magnificent orange-red needles that melt at <B> 209-2110 </B>.



  The 2-phenoxyquinizarin obtained in this way is sulfated by dissolving it in ten times the amount of a sulfuric acid which contains about 2% free SO 2. Isolation of the formed sulfonic acid as usual as a sodium salt, which is soluble in water. The solution of the sulfonic acid in strong sulfuric acid is blue, tinged red.

PATENTANSPRUCH: Verfahren zur Darstellung eines Konden sationsproduktes der Anthrachinonreihe, da durch gekennzeichnet, dass man 2-Halogen- chinizarin mit Phenol umsetzt und das so erhältliche 2-Phenogychinizarin mit einem sulfierenden Mittel bis zur Aufnahme einer Sulfogruppe behandelt. PATENT CLAIM: Process for the preparation of a condensation product of the anthraquinone series, characterized in that 2-haloquinizarine is reacted with phenol and the 2-phenogychinizarine thus obtainable is treated with a sulfating agent until a sulfo group is absorbed. Die so erhaltene 2-Phenoxychinizarin- Monosulfosäure löst sich in Schwefelsäure blaurot und bildet ein gut kristallisiertes in Wasser lösliches Natriumsalz. Sie soll ins besondere für die Herstellung von Farblacken Verwendung finden. The 2-phenoxyquinizarin monosulfonic acid obtained in this way dissolves in sulfuric acid blue-red and forms a well-crystallized sodium salt which is soluble in water. It should be used in particular for the production of colored lacquers.
