Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthrachinonreihe.       Gegenstand     ,dieses    Zusatzpatentes     ist    ein  Verfahren zur Darstellung eines sauren     Chro-          mierungsfarbs.toffes    der     Anthrachinonreihe,          welches        dadurch        gekennzeichnet    ist,     daZ    man  1-     amino-4-bromanthrachinon    -2     -sulfosaures     Natrium mit     3'-Amino-4'-methoxybenzyl-4-          oxy-3-m,

  ethyl-5-carboxyphenylsulfon    konden  siert.  



  <I>Beispiel:</I>  12     Gewichtsteile        1-a,mino-4-bromanthra-          chinon-2-sulfosaures    Natrium     werden    mit 15       Gewichtsteilen    3'-     Amina-4'-methoxybenzyl-          4-oxy-,3-methyl-5-carboxyphenylsulfon    der  folgenden Formel:

  Der     entstandene    Farbstoff färbt nach  seiner Isolierung und     Reinigung        Wolle    in    blauen Tönen, welche sich durch     Nachchro-          mieren        unter    Übergang in eine     grünstickigere          Nuance    in     ihren        EChthelten    wesentlich     ver-          bessseren        lassen.  



  Process for the preparation of an acidic chromating dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of an acidic chromating agent of the anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinone -2-sulfonic acid is sodium with 3'-amino-4'-methoxybenzyl-4 - oxy-3-m,

  ethyl-5-carboxyphenyl sulfone condenses.



  <I> Example: </I> 12 parts by weight of 1-a, mino-4-bromanthraquinone-2-sulfonic acid sodium are mixed with 15 parts by weight of 3'-amina-4'-methoxybenzyl-4-oxy-, 3-methyl- 5-carboxyphenyl sulfone of the following formula:

    
EMI0001.0023
    Heat 7 parts by weight of soda ash and 1 part by weight of copper chloride in 160 parts by weight of water to the boil for about 5 hours.



  After it has been isolated and cleaned, the resulting dye dyes wool in blue tones, which can be significantly improved by re-chroming with a transition to a greener shade.

PATENTANSPRUCH: Verfahren zur Darstellung eines sauren Chromierungsfarbstoffes der Anthrachinon- reihe,dadurch gekennzeichnet, @dass, man 1- amino-4-bromanthrachinon-2,- sulfosaures Na trium mit 3'-Amino-4'-methoxybenzyl-4-oxy- 3-methyl-5-carboxyphenylsulfdn kondensiert. Der so erhaltene Farbstoff färbt Wolle in blauen Tönen, welche durch Na, PATENT CLAIM: Process for the preparation of an acidic chromating dye of the anthraquinone series, characterized in that, 1-amino-4-bromoanthraquinone-2, - sulfonic acid sodium with 3'-amino-4'-methoxybenzyl-4-oxy-3 -methyl-5-carboxyphenylsulfdn condensed. The dye obtained in this way dyes wool in blue tones, which by Na, chchroMie- ren in eine grünstickigere Nuance von guten Echth-eitscigenschaften übergehen. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Kondensation .der Reaktionskomponenten durch Erhitzen in Wasser in Gegenwart von Natriumcarbonat und Kupferchlorür bewirkt. Chromium changes into a greener shade of good real-life properties. SUBCLAIM: Process according to claim, characterized in that the condensation of the reaction components is effected by heating in water in the presence of sodium carbonate and copper chloride.
