Description

  

  Verfahren zur Herstellung eines in roten Tönen färbenden     ehromhaltigen    Farbstoffes.    Es wurde gefunden,     dass    man einen in  roten Tönen färbenden     ehromhaltigen    Farb  stoff erhalten kann, wenn man :den     Azofarb-          stoff    aus     diazotierter        4-Chlor-2-amino-l-phe-          nol-6-sulfonsäure    und     1-(2'-Sülfo-)phenyl-3-          methyl-5-pyrazolon    mit chromabgebenden       Mitteln    behandelt.  



  Der     erhaltene        chromhaltige    Farbstoff  stellt ein braunrotes Pulver dar, :das sich  in. Wasser mit roter, in 10%iger Natron  lauge oder     Sodalösung    mit oranger und in  konzentrierter Schwefelsäure     mit    gelb  brauner Farbe löst. Er färbt Wolle aus  schwefelsaurem Bade in gleichmässigen,  echten     gelbstichigroten    Tönen.

      <I>Beispiel:</I>  54 Teile des     Azofarbstoffes    aus     .diazotier-          ter        4-Chlor-2=amino-l-phenol-6-sulfonsäure     und     1-(2'-Sulfo-)phenyl-3-m:ethyl-5-pyrazolon     werden mit 800 Teilen Wasser und 120 Tei  len einer 18%igen     Chromsulfatlösung    meh-         rere    Stunden unter     Rückfluss    zum Sieden er  hitzt. Die Chromverbindung wird mit Koch  salz     abgeschieden,        @abfiltriert    und getrocknet.



  Process for the preparation of an Ehrom-containing dye which coloring in red shades. It has been found that you can obtain an Ehrom-containing dye which stains in red shades if: the azo dye from diazotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and 1- (2'- Sülfo-) phenyl-3-methyl-5-pyrazolon treated with chromium donating agents.



  The chromium-containing dye obtained is a brown-red powder: which dissolves in water with red, in 10% sodium hydroxide solution or soda solution with orange and in concentrated sulfuric acid with a yellow-brown color. He dyes wool from sulfuric acid bath in even, genuine yellowish-red tones.

      <I> Example: </I> 54 parts of the azo dye from .diazotized 4-chloro-2 = amino-1-phenol-6-sulfonic acid and 1- (2'-sulfo-) phenyl-3-m: ethyl -5-pyrazolone are refluxed with 800 parts of water and 120 parts of an 18% chromium sulfate solution for several hours. The chromium compound is deposited with sodium chloride, filtered off and dried.
