Description

  

  Verfahren zur Darstellung eines neuen,     wasserlöslichen        Farbstoffes     der     Anthraehinonreihe.       Es wurde die     überraschende        Beobachtung     gemacht, dass man neue Farbstoffe der     An-          thrachinonreihe    erhält, wenn man     Anthra-          chinonderivate    der allgemeinen Formel  
EMI0001.0010     
         worin    X = Wasserstoff oder einen     Amino-,          Alkylamino-    oder     Arylaminorest    bedeutet  und wobei sowohl der     Arylamino-,

      der     An-          thraehinon,    wie auch der     Benzanthronrest          Substituenten,        wie    z. B. Halogen, Cyan,     Oxy,          Alkoxy,        Phenoxy    und     Alkyl    enthalten kön  nen, mit     sulfierenden    Mitteln behandelt.  



  Die     Sulfierung    der oben     genannten        An-          thrachinonderivate    wird     vorteilhafterweise       mit     Oleum    geeigneter     Konzentration        bezw.     mit     Chlorsulfonsäure    und bei zum Beispiel  20 bis<B>150'</B> C gegebenenfalls in Gegenwart  von Borsäure     bezw.    von Metallsalzen durch  geführt.

       Enthalten.    die Ausgangsprodukte  gegen     Sulfogruppen    austauschfähige Atome  oder Gruppen, so     kann    man die     Sulfogruppe     durch     Erhitzen    dieser Verbindungen mit       Alkalisulfiten    in Gegenwart von geeigneten       Lösungsmitteln,    wie z. B. Phenol,     einführen.     



  Die nach dem vorliegenden Verfahren er  hältlichen Farbstoffe färben tierische     Fasern     und besitzen ausgezeichnete Echtheitseigen  schaften, insbesondere eine aussergewöhnliche  Beständigkeit gegen die saure Walke.  



  Das vorliegende Verfahren betrifft die  Darstellung eines neuen, wasserlöslichen     An-          thrachinonfarbstoffes        und    ist dadurch     gekenm-          zeiohnet,        @dass@    man     1-Anilido-4-(Bz-l,:benz-          anthronylamino)-ianth!racMno#n    mit     @Scahwie-          feJsäure        behandelt.     



  Der erhaltene Farbstoff stellt ein grau  schwarzes Pulver dar, welches in Schwefel-      säure mit blauer     Farbe    löslich ist und Wolle  in schönen     rötlichgrauen    Tönen von grosser  Echtheit anfärbt.  



  <I>Beispiel:</I>  5 Teile     1-Anilido-4-(Bz-l-benzantlii-onyl-          amino)-antliraehinon    (erhalten durch Kon  densation von     1.4-Aminoanilidoanthraehinon     mit     Bz-l-halogenbenzanthron),    4 Teile Glau-         bersalz    entwässert, werden so lange mit 40  Teilen     Oleum    10 bis 15     %    bei Temperaturen  von 40 bis 80   gerührt, bis eine Probe voll  ständig wasserlöslich geworden ist. Der Farb  stoff wird durch Eingiessen in Eis oder Was  ser isoliert.  



  Der neue Farbstoff entspricht der Formel  
EMI0002.0010     
    und färbt Wolle in schönen     rötlichgrauen     Tönen von grosser Echtheit an. Der Farbstoff  stellt ein grauschwarzes Pulver dar, welches  in     SehNvefelsäure    mit blauer Farbe löslich ist.



  Process for the preparation of a new, water-soluble dye of the anthraehinone series. The surprising observation was made that new dyes of the anthrachinone series are obtained if anthrachinone derivatives of the general formula are obtained
EMI0001.0010
         where X = hydrogen or an amino, alkylamino or arylamino radical and where both the arylamino,

      the anthraehinone, as well as the benzanthrone radical substituents such. B. halogen, cyano, oxy, alkoxy, phenoxy and alkyl contain NEN treated with sulfonating agents.



  The sulphonation of the abovementioned anthraquinone derivatives is advantageously BEZW with oleum of suitable concentration. with chlorosulfonic acid and at, for example, 20 to 150 ° C, optionally in the presence of boric acid or. of metal salts carried out.

       Contain. the starting materials for atoms or groups which can be exchanged for sulfo groups, the sulfo group can be removed by heating these compounds with alkali metal sulfites in the presence of suitable solvents, such as. B. phenol, introduce.



  The dyes obtainable by the present process dye animal fibers and have excellent fastness properties, especially exceptional resistance to acidic fulling.



  The present method relates to the preparation of a new, water-soluble anthrachinone dye and is characterized by the fact that @ one 1-anilido-4- (Bz-1,: benz-anthronylamino) -ianth! RacMno # n with @ Scahwie- FeJ acid treated.



  The dye obtained is a gray-black powder which is soluble in sulfuric acid with a blue color and dyes wool in beautiful reddish-gray shades of great fastness.



  <I> Example: </I> 5 parts of 1-anilido-4- (Bz-l-benzantlii-onyl-amino) -antliraehinone (obtained by condensation of 1,4-aminoanilidoanthraehinone with Bz-l-halogenobenzanthrone), 4 parts of Glau - Dehydrated oversalt, are stirred with 40 parts of oleum 10 to 15% at temperatures of 40 to 80 until a sample has become completely water-soluble. The dye is isolated by pouring it into ice or water.



  The new dye conforms to the formula
EMI0002.0010
    and dyes wool in beautiful reddish-gray tones of great authenticity. The dye is a gray-black powder, which is soluble in septic acid with a blue color.
