Description

  

  Verfahren zur Herstellung     eines    ehr     omhaltigen    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     1-Amino-2-oxynaphtha-          lin-4-sulfosäure    und     1-(3'-Sulfamido)-phenyl-          3-methyl-5-pyrazolon        finit    Chromsulfat be  handelt.  



  Der gebildete Farbstoff stellt ein rotes  Pulver dar, das sich in verdünnter Soda mit       gelbstichig    roter Farbe löst und Wolle aus  schwefelsaurem Bade in     Rosatönen    färbt.  



  <I>Beispiel:</I>  50,4 Teile des Farbstoffes aus dianotier  ter     1-Aniino-2-oxynaphthalin-4-sulfosäure    und       1-(3'-Sulfamido)-phenyl-3-methyl-5-pyrazolon     werden in 2000 Teilen Wasser gelöst und  reit einer aus 9,1 Teilen     Cr--,03    und 14,6  Teilen     H2S04    erhaltenen     Ohromsulfatlösung       während 24 Stunden am     Rückfluss    zum Kochen  erhitzt. Hierauf lässt man erkalten,     filtriert     die ausgeschiedene     Chromverbindung    ab und  trocknet bei mässiger Temperatur.



  Process for the production of a dye containing ore. It was found that a new chromium-containing dye which contains 1 atom of chromium for every chromable group of the dye molecule; is obtained when the dye is from dianotized 1-amino-2-oxynaphthalin-4-sulfonic acid and 1- (3'-sulfamido) phenyl 3-methyl-5-pyrazolone finite chromium sulfate be.



  The dye formed is a red powder that dissolves in dilute soda with a yellowish red color and dyes wool from sulfuric acid bath in shades of pink.



  <I> Example: </I> 50.4 parts of the dye from dianotized 1-aniino-2-oxynaphthalene-4-sulfonic acid and 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone are used in 2000 parts of water are dissolved and an ohrom sulfate solution obtained from 9.1 parts of Cr -, O 3 and 14.6 parts of H 2 SO 4 is heated to boiling under reflux for 24 hours. It is then allowed to cool, the precipitated chromium compound is filtered off and dried at a moderate temperature.

PATENTANSPRUCH Verfahren zur Herstellung eines chroin- hn,ltigen Farbstoffes, der auf jede chrornier- bare Gruppe des Farbstöffmoleküls 1 Atom Chlor enthält, dadurch gekennzeichnet, dass man den Farbstoff aus dianotierter 1-Amino- 2-oxynaphthalin-4-sulfosäure und 1-(3'-Sulf- amidoy - phenyl - 3 - methyl - 5 - pyrazolon mit Chromsulfat behandelt. PATENT CLAIM A process for the preparation of a chromium-containing dyestuff which contains 1 atom of chlorine for every chromable group of the dyestuff molecule, characterized in that the dyestuff is made from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and 1- ( 3'-sulfamido-phenyl-3-methyl-5-pyrazolone treated with chromium sulfate. Der gebildete Farbstoff stellt ein rotes Pulver dar, das sich in verdünnter Soda mit gelbstichig roter Farbe löst und Wolle aus schwefelsaurem Bade in Rosatönen färbt. The dye formed is a red powder that dissolves in dilute soda with a yellowish red color and dyes wool from sulfuric acid bath in shades of pink.
