Description

  

  Zusatzpatent zum Hauptpatent Nr. 152880.         -'erfahren    zur     Herstellung    eines     ehromhaltigen        Farbstoffes.       Es wurde gefunden, dass ein neuer     chrom-          haltiger        .Farbstoff,    der auf jede     ehromierbare     Gruppe des     Farbstoffmoleküls    1 Atom Chrom  enthält, erhalten wird, wenn man den Farb  stoff aus     diazotierter        1-Amirio-2-oxynaph-          tlialin-4-sulfosäure    und     1-Oxynaphthalin    mit  Chromsulfat behandelt.  



  Der gebildete Farbstoff stellt ein dunkel  blaues Pulver dar, das sich in     verdünnter     Soda mit     rotstichig    blauer Farbe löst     und     Wolle aus     schwefelsaurem    Bad in     grünstichig     blauen Tönen färbt.  



  <I>Beispiel:</I>  39,4 Teile des Farbstoffes aus     diazotierter          1-Ainino-2-oxynaphthalin-4-sulfosäure    und     1-          Oxynaphthalin    werden in 2000 Teilen Wasser       aufgekocht    und mit einer aus 9,1 Teilen       Cr20s    und 14,6 Teilen     132S04    erhaltenen       Chromsulfatlösung    während 30 Stunden am       Riiel@flufküliler    zum Kochen erhitzt. Die    Chromverbindung scheidet sich nach dem       Erkalten    aus der     Lösung    aus; sie wird ab  filtriert, ausgewaschen und bei mässiger  Temperatur getrocknet.



  Additional patent to the main patent No. 152880. -'erfahren for the production of an Ehrom-containing dye. It has been found that a new chromium-containing dyestuff which contains 1 atom of chromium for every honorable group of the dyestuff molecule is obtained if the dyestuff is obtained from diazotized 1-aminophthalene-4-sulfonic acid and 1 -Oxynaphthalene treated with chromium sulfate.



  The dye formed is a dark blue powder that dissolves in dilute soda with a reddish blue color and dyes wool from a sulfuric acid bath in greenish blue tones.



  <I> Example: </I> 39.4 parts of the dye from diazotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 1-oxynaphthalene are boiled in 2000 parts of water and mixed with one of 9.1 parts of Cr20s and 14, 6 parts of 132S04 obtained chromium sulfate solution heated to boiling on a Riiel @ flufküliler for 30 hours. The chromium compound separates out of the solution after cooling; it is filtered off, washed and dried at a moderate temperature.
