Description

  

  Verfahren zur Herstellung eines braunen     liiipenfarbstofes    der     Anthraehinonreihe.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines braunen       Küpenfarbstoffes    der     Anthrachinonreihe,    da  durch gekennzeichnet, dass man 1     Mol.    2.     6-          Dimerkaptoanthracen    mit 2     Mol.    der     1-          Chloranthrachinon-2-carbonsäure    kondensiert  und das so gebildete 2 .

       6-Di-(2'-carboxy-1'-          antrachinonyl-thio)-anthracen    durch Einwir  kung von sauren Kondensationsmitteln in das       Thioxanthon    überführt.  



  Der neue Farbstoff löst sich in konzen  trierter Schwefelsäure mit roter Farbe und  färbt aus. der grünen     Hydrosulfitküpe    Baum  wolle in kräftigen und echten gelbbraunen  Tönen.  



  <I>Beispiel:</I>  Durch Kondensation von 2     Mol.        1-Chlor-          anthrachinon-2-carbonsäure    mit 1     Mol.    2.     6-          Dimerkaptoanthracen    erhält man in gleicher    Weise wie im Beispiel des Hauptpatentes an  gegeben eine     Dicarbonsäure,    die trocken ein  oranges Pulver darstellt. das in Alkalien mit  oranger, in konzentrierter Schwefelsäure mit       braunoliver,    rasch in Grüngrau     übergehende    r  Farbe löslich ist.  



  15 Teile dieser     Dicarbonsäure    werden in  240 Teilen     Trichlorbenzol    mit     12,.1    Teilen       Phosphorpentaehlorid    nach den Angaben des  Beispiels des Hauptpatentes in das     Di-          thioxanthon    übergeführt.



  Process for the production of a brown lipstick of the anthraehinone series. The present patent relates to a process for the preparation of a brown vat dye of the anthraquinone series, characterized in that 1 mol. 2. 6- Dimerkaptoanthracene is condensed with 2 mol. Of the 1-chloroanthraquinone-2-carboxylic acid and the 2.

       6-Di- (2'-carboxy-1'-antrachinonyl-thio) -anthracene converted into the thioxanthone by the action of acidic condensing agents.



  The new dye dissolves in concentrated sulfuric acid with a red color and stains. the green hydrosulfite vat tree wool in strong and genuine yellow-brown tones.



  <I> Example: </I> By condensation of 2 mol. 1-chloro-anthraquinone-2-carboxylic acid with 1 mol. 2. 6- Dimerkaptoanthracene, in the same way as in the example of the main patent, a dicarboxylic acid is obtained which is dry represents an orange powder. which is soluble in alkalis with orange, in concentrated sulfuric acid with brown-olive color, which quickly turns green-gray.



  15 parts of this dicarboxylic acid are converted into the dioxanthone in 240 parts of trichlorobenzene with 12.1 parts of phosphorus pentahloride according to the information in the example of the main patent.
