Description

  

      Verfahren    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man das     6-Nitro-2-          amino-1.-oxybenzol    - 4 -     sulfamid        diazotiert,     hierauf mit 1 -     (3'-Sulfamido)-phenyl-5-py-          razolon-3-karbonsäure    kuppelt und den so  erhaltenen Farbstoff mit     Fluorchrom    be  handelt.

   Der neue Farbstoff bildet ein       orangebraunes    Pulver, löst sich in Wasser  und in 10     %iger    Natronlauge mit oranger,  in     konzentrierter    Schwefelsäure mit gelber  Farbe und färbt Wolle aus saurem Bade in  orangen Tönen mit vorzüglichen     Eigen-          scb        aften.            Beispiel:

       ?3,3 Teile     6-Nitro-2-amino-l-oxybenzol-          4-sulfamid    werden in üblicher Weise mit 6,9  Teilen     Natriumnitrit        diazotiert.    Die     Diazo-          lösung    lässt man in eine eiskalte Lösung von  28,3 Teilen 1 -     (3'-Sulfamido)-phenyl-5-py-          razolon-3-larbonsäure    und 30 Teilen Soda in       ?50    Teilen Wasser unter Rühren einfliessen.  Die Reaktionsmasse wird nach vollendeter  Kupplung auf 50   angewärmt und der Farb  stoff mit Kochsalz     ausgesalzen    und in üb  licher Weise isoliert.

      50 Teile des so erhaltenen Farbstoffes  werden in 1500 Teilen Wasser kochend ge  löst. Man versetzt hierauf mit einer Fluor  chromlösung entsprechend<B>15,2</B> Teilen     Cr203,     kocht unter Zusatz von Glaspulver längere  Zeit am     Rückflusskühler    und scheidet die  Chromverbindung durch     Aussalzen    oder  Eindampfen und     Aussalzen    aus.



      Process for the production of a new dye. It has been found that a new dye is obtained if the 6-nitro-2-amino-1-oxybenzene-4-sulfamide is diazotized, then with 1 - (3'-sulfamido) -phenyl-5-pyrazolone -3-carboxylic acid is coupled and the dye thus obtained is treated with fluorochrome.

   The new dye forms an orange-brown powder, dissolves in water and in 10% sodium hydroxide solution with orange, in concentrated sulfuric acid with yellow color and dyes wool from acid baths in orange shades with excellent properties. Example:

       3.3 parts of 6-nitro-2-amino-1-oxybenzene-4-sulfamide are diazotized in the usual way with 6.9 parts of sodium nitrite. The diazo solution is allowed to flow into an ice-cold solution of 28.3 parts of 1- (3'-sulfamido) -phenyl-5-pyrazolone-3-carbonic acid and 30 parts of soda in 50 parts of water with stirring. After coupling is complete, the reaction mass is heated to 50 and the dye is salted out with sodium chloride and isolated in the usual way.

      50 parts of the dye thus obtained are dissolved at the boil in 1500 parts of water. A fluorochromium solution corresponding to <B> 15.2 </B> parts of Cr203 is then added, the mixture is boiled for a long time in a reflux condenser with the addition of glass powder and the chromium compound is separated out by salting out or evaporation and salting out.
