Description

  

      Zusatzpatent    zum Hauptpatent Nr. 152880.    Verfahren zur Herstellung eines     chromhaltigen        Farbstoffes.       Es wurde gefunden, dass ein neuer     chrom-          haltiger    Farbstoff, der auf jede     chromierbare     Gruppe des     Farbsto''irroleküls    1 Atom Chrom  enthält, erhalten wird, wenn man den Farb  stoff aus dianotiertem     4-Chlor-2-amino-l-phenol     und     2-Oxynaphthalin-6-sulfosäure    mit Chrom  sulfat behandelt.  



  Der gebildete Farbstoff stellt ein dunkel  gefärbtes Pulver dar, das sich in verdünnter  Soda mit rotvioletter     Farbe    löst und Wolle  aus schwefelsaurem Bade in rotstickig vio  letten Tönen färbt.  



  <I>Beispiel:</I>  37,8 Teile des Farbstoffes aus dianotiertem       4-Chlor-2-amino-l-phenol    und     2-Oxytraphtha-          lin-6-sulfosäure    werden in 2000 Teilen Wasser  aufgekocht und mit einer aus 9,1 Teilen       Cr20s    und 14,6 Teilen     112S04    erhaltenen       Chromsulfatlösurrg    während 24-30 Stunden    am     Rückflusskühler    zum Kochen erhitzt. Hier  auf wird die gebildete Chromverbindung nach  dein Erkalten     abfiltriert    und bei mässiger Tem  peratur getrocknet.



      Additional patent to main patent No. 152880. 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 made from dianotized 4-chloro-2-amino-1-phenol and 2 -Oxynaphthalene-6-sulfonic acid treated with chromium sulfate.



  The dye formed is a dark-colored powder that dissolves in dilute soda with a red-violet color and dyes wool from sulfuric acid bath in red-sticky violet shades.



  <I> Example: </I> 37.8 parts of the dye from dianotized 4-chloro-2-amino-1-phenol and 2-oxytraphthalin-6-sulfonic acid are boiled in 2000 parts of water and mixed with one of 9, 1 part of Cr20s and 14.6 parts of 112S04 obtained chromium sulfate solution heated to boiling for 24-30 hours on a reflux condenser. Here the chromium compound formed is filtered off after cooling and dried at a moderate temperature.

PATENTANSPRUCH: Verfahren zur Herstellung eines chrom- haltigen Farbstoffes, der auf jede chrornier- bare Gruppe des Farbstoffmoleküls 1 Atonr Chrom enthält, dadurch gekennzeichnet, dass man den Farbstoff aus dianotiertem 4-Chlor- 2-anrino-l-phenol urrd2-Oxynaphtbalin-ti-sulfo- säure mit Chromsulfat behandelt. PATENT CLAIM: Process for the production of a chromium-containing dye which contains 1 atom of chromium for every chromable group of the dye molecule, characterized in that the dye is made from dianotated 4-chloro-2-anrino-1-phenol urrd2-oxynaphtbalin-ti sulfonic acid treated with chromium sulfate. Der gebildete Farbstoff stellt ein dunkel gefärbtes Pulver dar, das sich in verdünnter Soda mit rotvioletter Farbe löst und Wolle aus schwefelsaurem Bade in rotstickig violetten Tönen färbt. The dye formed is a dark-colored powder that dissolves in dilute soda with a red-violet color and dyes wool from sulfuric acid bath in red-sticky violet shades.
