Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 240992.    Verfahren zur Herstellung eines     ehromierten    Farbstoffes.         Gegenstand    vorliegenden Patentes ist ein  Verfahren zur     Herstellung    eines     chromierten     Farbstoffes.

   Das Verfahren ist dadurch ge  kennzeichnet, dass der Farbstoff aus     diazo-          tierter        2-Amino-benzol-l-carbonsäure    und       1-Naphthol    - 8     -sulfonsäure-    3     -sulf        onsäure-N-          äthyl-N-phenyl-amid    mit     chromsalicylsaurem     Ammonium behandelt wird.  



  Der entstandene neue chromhaltige     Kom-          plexf        arbstof    f ist ein dunkelweinrotes, in  Wasser gut lösliches Pulver. Er färbt  Wolle aus ameisensaurem Bad in     reinen,     weinroten Tönen von guter Gleichmässigkeit.  Die Färbungen zeichnen sich durch gute  Walk-, Schweiss-, Reib- und sehr gute Licht  echtheit aus.  



       Beispiel:     59,9     Teile        Dinatriumsalz    des Farbstoffes       2-Amino-benzol-l-carbonsäure        ->        1-Naph-          thol    - 8     -sulf        onsäure-3-oulfonsäure-N-äthyl-N-          phenyl-amid    werden     in    1000 Teilen Wasser  verrührt und nach Zugabe von 240     Teilen     einer Lösung von     chromsalicylsaurem    Ammo-         nium    entsprechend 9,

  1 Teilen Chromoxyd so  lange unter     Rückfluss    beim Siedepunkt     ge-          rührt,        bis    der Farbstoff in komplexe Form  übergegangen     ist,    was nach 15-20 Stunden  der Fall     ist.    Die     tiefrote    Lösung     wird    heiss  von     etwas        unlöslichem    chromhaltigem Neben  produkt     filtriert    und der     Chromkomplegfarb-          stoff    durch Sättigen mit Kochsalz isoliert.



  <B> Additional patent </B> to main patent no. 240992. Process for the production of an honored dye. The present patent relates to a process for the preparation of a chromium-plated dye.

   The process is characterized in that the dye is treated with diazo-tated 2-amino-benzene-1-carboxylic acid and 1-naphthol-8-sulfonic acid-3-sulfonic acid-N-ethyl-N-phenyl-amide with chromsalicylic acid ammonium becomes.



  The resulting new chromium-containing complex dye is a dark wine-red powder that is readily soluble in water. He dyes wool from an acidic bath in pure, wine-red tones of good evenness. The dyeings are characterized by good flexing, perspiration, rubbing and very good lightfastness.



       Example: 59.9 parts of the disodium salt of the dye 2-amino-benzene-1-carboxylic acid -> 1-naphthol - 8-sulfonic acid-3-sulfonic acid-N-ethyl-N-phenyl-amide are stirred in 1000 parts of water and after adding 240 parts of a solution of chromsalicylic acid ammonium corresponding to 9,

  1 part chromium oxide stirred under reflux at the boiling point until the dye has changed into a complex form, which is the case after 15-20 hours. The deep red solution is filtered while hot from some insoluble chromium-containing by-product and the chromium complex dye is isolated by saturating it with sodium chloride.
