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 dianotierter     4-Chlor-2-amino-l-phenol-          5-sulfosäure    und     2,4-Dioxychinolin    mit Chrom  sulfat behandelt.  



  Der gebildete     Farbstoff    stellt ein dunkel  rotes Pulver dar, das sich in verdünnter Soda  mit     gelbstichig    roter Farbe löst und Wolle  aus schwefelsaurem Bade in bordeauxroten  Tönen färbt.    <I>Beispiel:</I>  39,5 Teile des Farbstoffes aus dianotierter       4-Chlor-2-amino-l-phenol.-5-sulfosäure    und 2,4  Dioxychinolin werden in 1500 Teilen Wasser  gelöst und mit einer aus 9,1 Teilen     Cr20s     und 14,6 Teilen     H2S04    erhaltenen     Chromsul-          fatlösung    während 20-24 Stunden zum Sie-    den erhitzt. Nach dem Erkalten filtriert man  den ausgeschiedenen Farbstoff ab und trocknet  bei mässiger Temperatur.



  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-5-sulfonic acid and 2,4-Dioxyquinoline treated with chromium sulfate.



  The dye formed is a dark red powder that dissolves in dilute soda with a yellowish red color and dyes wool from sulfuric acid bath in claret-red tones. <I> Example: </I> 39.5 parts of the dye from dianotized 4-chloro-2-amino-l-phenol.-5-sulfonic acid and 2,4 dioxyquinoline are dissolved in 1500 parts of water and treated with one of 9, 1 part of Cr20s and 14.6 parts of H2S04 obtained the chromium sulfate solution heated to boiling for 20-24 hours. After cooling, the precipitated dye is filtered off and dried at a moderate temperature.

PATENTANSPRUCH: Verfahren zur Herstellung eines chrom- haltigen Farbstoffes, der auf jede chromier- bare Gruppe des Farbstoffmoleküls 1 Atom Chrom enthält, dadurch gekennzeichnet, dass man den Farbstoff aus dianotierter 4-Chlor- 2-amino-l-phenol-5-sulfosäure und 2,4-Dioxy- chinolin mit Chromsulfat behandelt. PATENT CLAIM: A process for the production of a chromium-containing dye which contains 1 atom of chromium for each chromable group of the dye molecule, characterized in that the dye is made from dianotated 4-chloro-2-amino-1-phenol-5-sulfonic acid and 2,4-Dioxyquinoline treated with chromium sulfate. Der gebildete Farbstoff stellt ein dunkel rotes Pulver dar, das sich in verdünnter Soda mit gelbstichig roter Farbe löst und Wolle aus schwefelsaurem Bade in bordeauxroten Tönen färbt. The dye formed is a dark red powder that dissolves in dilute soda with a yellowish red color and dyes wool from sulfuric acid bath in claret-red tones.
