Description

  

  Verfahren zur     Herstellung    eines     chromhaltigen        Farbstoffes.       Es wurde gefunden, dass ein neuer     chrom-          haltiger    Farbstoff, der auf jede     chromierbare     Gruppe des     Farbstoffmoleküls    1 Atom Chrom  enthält, erhalten wird, wenn man den Farb  stoff aus dianotiertem     4-Sulfamido-2-amino-l-          phenol    und     1-(3'-Sulfamido)-phenyl-3-methyl-          5-pyrazolon    mit Chromsulfat behandelt.  



  Der gebildete Farbstoff stellt ein braun  gelbes Pulver dar, das sich in verdünnter  Soda mit oranger Farbe löst und Wolle aus  schwefelsaurem Bade in rotorangen Tönen  färbt.  



  <I>Beispiel:</I>  45,4 Teile des Farbstoffes aus dianotiertem       4-Sulfamido-2-amino-l-phenol    und     1-(3'-Sulf-          amido)-pheriyl-3-methyl-5-pyrazolon    werden in  3000 Teilen Wasser mit 9,1 Teilen     Cr20s    und  11,7 Teilen H2S04 während 30 Stunden am       Rück$usskühler    gekocht. Hierauf wird der         Farbstoff    durch Zugabe von Kochsalz abge  schieden, filtriert und getrocknet.



  Process for the production of a chromium-containing dye. It has been found that a new chromium-containing dye, which contains 1 atom of chromium for each chromable group of the dye molecule, is obtained if the dye is obtained from dianotized 4-sulfamido-2-amino-1-phenol and 1- (3 '-Sulfamido) -phenyl-3-methyl-5-pyrazolone treated with chromium sulfate.



  The dye formed is a brown-yellow powder that dissolves in dilute soda with an orange color and dyes wool from a sulfuric acid bath in red-orange tones.



  <I> Example: </I> 45.4 parts of the dye are made from dianotized 4-sulfamido-2-amino-1-phenol and 1- (3'-sulfamido) -pheriyl-3-methyl-5-pyrazolone Boiled in 3000 parts of water with 9.1 parts of Cr20s and 11.7 parts of H2S04 for 30 hours on a return condenser. The dye is then separated out by adding sodium chloride, filtered and dried.
