Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthrachinonreihe       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines sauren     Chro-          mierungsfarbstoffes    der     Anthrachinonreihe,     welches dadurch gekennzeichnet ist,     @dass     man     1-amino-4-bromanthrachinon-2-sulfosau-          res        Natrium    mit     (3'-Amino-benzoyl-5-amino)-          2-oxyphenyl-l-carbonsäure    kondensiert.  



  <I>Beispiel:</I>  40     Gewichtsteile        1-amino-4-br        manthra-          chinon-2-sulfosaures    Natrium, 35 Gewichts  teile     (3'-Aminobenzoyl-5-amino)-2-ogyphenyl-          1-carbonsäure,    35     Gewichtsteile    Soda     calc.,     2,5 Gewichtsteile     Natriumbicarbonat,    2,5 Ge  wichtsteile     Kupferchlortir    und 600 Teile  Wasser werden bei 70 bis<B>80'</B> gerührt.

   Das       Reaktionsgemisch,    wird     nach.    dem Erkalten  abgesaugt und mit 5 %     iger        Kochsalzlösung,ge-          waschen.    Zur weiteren     Reinigung    löst man  das Produkt in verdünntem     wässrigen    Am  moniak und fällt nach dem Filtrieren den  Farbstoff durch Zusatz von Salzsäure. Man  erhält so ein blaues Pulver, welches sich  in Wasser mit blauer Farbe löst. Wolle     wird     aus saurer     Flotte    in blauen Tönen gefärbt.    Zur Erhöhung der     Echtheiten    werden die  Färbungen mit chromabgebenden     Mitteln     nachbehandelt.



  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 dye of the anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinone-2-sulphonic acid sodium with (3 ' -Amino-benzoyl-5-amino) - 2-oxyphenyl-1-carboxylic acid condensed.



  <I> Example: </I> 40 parts by weight of 1-amino-4-br manthraquinone-2-sulfonic acid sodium, 35 parts by weight (3'-aminobenzoyl-5-amino) -2-ogyphenyl-1-carboxylic acid, 35 Parts by weight of soda calc., 2.5 parts by weight of sodium bicarbonate, 2.5 parts by weight of copper chlorotire and 600 parts of water are stirred at 70 to 80 '.

   The reaction mixture is after. Sucked off after cooling and washed with 5% saline solution. For further purification, the product is dissolved in dilute aqueous ammonia and, after filtration, the dye is precipitated by adding hydrochloric acid. This gives a blue powder which dissolves in water with a blue color. Wool is dyed in blue tones from acidic liquor. To increase the fastness properties, the dyeings are aftertreated with chromium-releasing agents.

PATENTANSPRUCH: Verfahren zur Darstellung eines sauren Chromierungsfarbstoffes der Anthrachinon- reihe, dadurch gekennzeichnet, dass man 1- amino-4-bromanthrachinon-2-sulfosaures Na trium mit (3'-Aminobenzoyl-5-amino)-2-oxy- phenyl-l-carbonsäure kondensiert. Der so erhältliche Farbstoff bildet ein blaues wasserlösliches Pulver, welches Wolle aus saurer Flotte in blauen Tönen färbt, die durch Nachchromieren in ihren Echtheits eigenschaften verbessert werden. 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'-aminobenzoyl-5-amino) -2-oxy-phenyl-l -carboxylic acid condensed. The dye obtainable in this way forms a blue, water-soluble powder which dyes wool from acidic liquor in blue tones, the fastness properties of which are improved by post-chrome plating. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass .die Kondensation der Reaktionskomponenten durch Erhitzen in Wasser in Gegenwart von Natriumcarbonat, Natriumbicarbonat und gupferchlorür be wirkt wird. SUBClaim: Process according to patent claim, characterized in that .the condensation of the reaction components is effected by heating in water in the presence of sodium carbonate, sodium bicarbonate and copper chloride.
