Description

  

  Verfahren zur Darstellung eines neuen     Kondensationsproduktes    der     Anthrachinonreihe.       Es wurde gefunden, dass man zu neuen  Verbindungen der     Anthrachinonreihe    der all  gemeinen Formel  
EMI0001.0004     
    worin     Ri    und     R2        Wasserstoff    oder     Alkyl,     A einen substituierten oder     unsubstituierten     Benzol-, Naphtalin- oder     Tetrahydronaphta-          linrest,    B eine     SO2-    oder     CO-gruppe,        C,          Wasserstoff,

          Alkyl-    oder     O$alkylrest,        C2     einen     Ogalkylrest    und X     Wasserstoff    oder  einen beliebigen     Substituenten    bedeuten, ge  langen kann, wenn man     Antbrachinonderivate     der allgemeinen Formel  
EMI0001.0023     
    worin     Ri    und     R2        Wasserstoff    oder     Alkyl,     Y eine Halogen- oder eine     Sulfogruppe    und  X     Wasserstoff    oder einen beliebigen     Substi-          tuenten    bedeuten,

   mit     Ogyalkylamiden    von  aromatischen     Aminosulfon-        bezw.        -carbon-          säuren    kondensiert und gegebenenfalls die  erhaltene Verbindung zwecks Einführung  einer     Sulfogruppe    in (-Stellung mit     Sulfiten     behandelt.  



  Die so erhaltenen Produkte eignen sich  zum Färben von tierischen Fasern, insbe  sondere zum Färben von Wolle, und sie  zeichnen sich durch ihre lebhafte Nuance  und gutes     Egalisiervermögen    aus.  



  Die Herstellung dieser Farbstoffe erfolgt  in der üblichen Weise, wobei es oft von      Vorteil ist, in Gegenwart organischer Lö  sungsmittel und in indifferenter Atmosphäre  zu arbeiten. Die Kondensationstemperatur  kann ferner in weiten Grenzen variiert wer  den. Werden als Ausgangsprodukte die ss  halogenierten     Anthrachinonderivate    verwen  det, so wird das     ss-Halogenatom    nach erfolgter  Kondensation durch Erhitzen mit     Sulfiten    in  üblicher Weise gegen eine     Sulfogruppe    aus  getauscht, wobei man mit Vorteil unter Druck  und bei erhöhter Temperatur arbeitet.  



  Das vorliegende Verfahren betrifft die  Darstellung eines     Anthrachinonfarbstoffes    und  ist dadurch gekennzeichnet, dass man     1-Amino-          4-bromanthrachinon-2-sulfonsäure    mit     m-          Amidobenzolsulfoäthanolamid    kondensiert.

      <I>Beispiel:</I>  25 Teile     1-amino-4-bromanthrachinon-2-          sulfonsaures    Natrium, 25 Teile     Natriumbi-          carbonat,    20 Teile     m-Amidobenzolsulfoäthanol-          amid        (H2N-C6H4-SO2-NHC2H4OH),    1 Teil  Kupferpulver und 600 Teile Wasser werden  so lange bei 50-100   gerührt, bis die Um  setzung beendet ist. Der gebildete     Farbstoff     kann durch Filtration isoliert werden. Durch  Umfällen aus heisser, verdünnter, angesäuerter  Kochsalzlösung kann der vom Kupfer be  freite Farbstoff gereinigt werden.  



  Der neue Farbstoff besitzt die Formel  
EMI0002.0018     
    und färbt Wolle in rotstickig blauen Tönen an.



  Process for the preparation of a new condensation product of the anthraquinone series. It has been found that new compounds of the anthraquinone series of the general formula
EMI0001.0004
    where Ri and R2 are hydrogen or alkyl, A is a substituted or unsubstituted benzene, naphthalene or tetrahydronaphthalene radical, B is an SO2 or CO group, C, hydrogen,

          Alkyl or O $ alkyl radical, C2 an Ogalkylrest and X signify hydrogen or any substituent, ge long if one Antbrachinonderivate of the general formula
EMI0001.0023
    where Ri and R2 are hydrogen or alkyl, Y is a halogen or a sulfo group and X is hydrogen or any substituent,

   with Ogyalkylamiden of aromatic aminosulfonbezw. -carboxylic acids condensed and optionally treated the compound obtained for the purpose of introducing a sulfo group in (-position with sulfites.



  The products thus obtained are suitable for dyeing animal fibers, in particular special for dyeing wool, and they are distinguished by their lively nuance and good leveling power.



  These dyes are prepared in the customary manner, and it is often advantageous to work in the presence of organic solvents and in an inert atmosphere. The condensation temperature can also be varied within wide limits. If the ss halogenated anthraquinone derivatives are used as starting materials, the ss-halogen atom is exchanged for a sulpho group in the usual way by heating with sulphites after condensation has taken place, it being advantageous to work under pressure and at elevated temperature.



  The present process relates to the preparation of an anthraquinone dye and is characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is condensed with m-amidobenzenesulfoethanolamide.

      <I> Example: </I> 25 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid sodium, 25 parts of sodium bicarbonate, 20 parts of m-amidobenzenesulfoethanolamide (H2N-C6H4-SO2-NHC2H4OH), 1 part of copper powder and 600 parts of water are stirred at 50-100 until the conversion is complete. The dye formed can be isolated by filtration. The copper-free dye can be purified by reprecipitation from hot, dilute, acidified saline solution.



  The new dye has the formula
EMI0002.0018
    and dyes wool in shades of red and blue.
