Description

  

      Verfahren    zur Darstellung eines sauren     Farbstoffes.       Es wurde gefunden, dass die     m-Amino-          benzoyl-o-berrzoesäuren    oder deren Derivate  durch Umsetzung mit     1-Amirto-4-halogenan-          thr,achinon-2-sulfosäur@en    wertvolle Produkte  ergeben, die als saure     Wollfarbstoffe    oder als  Ausgangsstoffe für andere     Farbstoffe    verwen  det werden können.  



  Zu den gleichen Produkten gelangt man,  wenn man die     rn-Aminobenzoyl-o-benzoesäu-          ren    mit     1-Amino-2.4-dihalogenanthrachino-          nen        kondensiert    und in den so gewonnenen       1-Amino-2-halogen-4-arylidoanthrachinonen     das Halogenatom, zweckmässig durch Behan  deln mit     Alkalisulfiten,    durch die     Sulfogruppe     ersetzt.  



       Gegenstand    vorliegender Erfindung ist ein  Verfahren zur Darstellung eines sauren     Farb-          stoffes,    welches dadurch gekennzeichnet ist,  dass man das     Natriumsalz    von     3'-Amino-4'-          methylbenzophenon-2-karbonsäure    der folgen  den Formel  
EMI0001.0023     
    mit     1-Amino-4-bromanthrachinon-2-sulfosau-          rem    Natrium kondensiert.

      <I>Beispiel:</I>  51 Gewichtsteile     3'-Amino-4'-methylben-          zophenon-2-karbonsäure    werden in 700 Ge  wichtsteilen Wasser und 30 Gewichtsteilen  wasserfreier Soda gelöst, mit 53 Gewichts  teilen     1-Amino-4-bromanthrachinon-2-sulfo-          saurem    Natrium und 2 Gewichtsteilen     Kup-          ferchlorür    versetzt. Die Mischung wird unter  gutem Rühren 15 Stunden in mässigem Sie  den erhalten. Nach der üblichen Aufarbeitung  erhält man den Farbstoff als blaues, kristal  linisches Pulver. Er liefert auf Wolle rein  blaue Färbungen von guter Licht-,     Wasch-          und        Walkechtheit.  



      Process for the preparation of an acidic dye. It has been found that the m-Amino-benzoyl-o-berrzoic acids or their derivatives by reaction with 1-Amirto-4-halogenanthr, aquinone-2-sulfonic acids give valuable products that can be used as acidic wool dyes or as starting materials for other dyes can be used.



  The same products are obtained if the rn-aminobenzoyl-o-benzoic acids are condensed with 1-amino-2,4-dihaloanthraquinones and the halogen atom is expediently obtained in the 1-amino-2-halo-4-arylidoanthraquinones obtained in this way by treating with alkali sulfites, replaced by the sulfo group.



       The present invention relates to a process for the preparation of an acidic dye, which is characterized in that the sodium salt of 3'-amino-4'-methylbenzophenone-2-carboxylic acid of the following formula is used
EMI0001.0023
    condensed with 1-amino-4-bromoanthraquinone-2-sulphonic acid rem sodium.

      <I> Example: </I> 51 parts by weight of 3'-amino-4'-methylbenzophenone-2-carboxylic acid are dissolved in 700 parts by weight of water and 30 parts by weight of anhydrous soda, with 53 parts by weight of 1-amino-4-bromoanthraquinone -2-sulphonic acid sodium and 2 parts by weight of copper chloride were added. The mixture will be kept in moderate condition for 15 hours with good stirring. After the usual work-up, the dye is obtained as a blue, crystalline powder. On wool it provides pure blue dyeings with good lightfastness, washfastness and milled fastness.
