Description

  

  Verfahren zur Herstellung eines neuen     ehromhaltigen        Farbstoffes.       Es wurde gefunden, dass man einen  neuen chromhaltigen Farbstoff erhält, wenn  man den     Azofarbstoff    aus     diazotierter        4-          Chlor-2-amino-l-phenol-6-,sulfo.säure    und     1-          Oxynaphthalin-5-.sulfosäure    mit chromabge  benden     Mitteln    behandelt.  



  Der erhaltene     chromhaltige    Farbstoff  stellt ein     violettbraunes    Pulver dar, das  sich in Wasser, sowie verdünnten Alkalien  mit rötlich     violetter,    in konzentrierter       Schwefels@.ure    mit grüner Farbe löst und  Wolle aus schwefelsaurem Bade in blau  violetten Tönen von guten Echtheitseigen  schaften färbt.  



  <I>Beispiel:</I>  44,7 Teile des     Azofarbstoffes    aus     di-          azotierter        4-Chlox-2-amino-l-phenol-6-sulfo-          säure    und     1-Oxynaphthalin-5-sulfosäure    wer  den in 1600 Teilen heissem Wasser gelöst,  mit 11,4 Teilen. Chromoxyd     (100%ig)    in       Form    einer     Chromfluoridlösung    versetzt  und das Reaktionsgemisch einige     Zeit        unter            Rückfluss    gekocht. Die entstandene Chrom  verbindung wird nach dem Erkalten mit.

    Kochsalz abgeschieden, filtriert, mit 10 %     iger     Kochsalzlösung gewaschen und getrocknet.



  Process for the preparation of a new Ehrom-containing dye. It has been found that a new chromium-containing dye is obtained if the azo dye consisting of diazotized 4-chloro-2-amino-1-phenol-6-, sulfonic acid and 1-oxynaphthalene-5-sulfonic acid is treated with chromium-releasing agents .



  The chromium-containing dye obtained is a violet-brown powder which dissolves in water and dilute alkalis with reddish violet, in concentrated sulfuric acid with a green color and dyes wool from sulfuric acid bath in blue-violet shades with good fastness properties.



  <I> Example: </I> 44.7 parts of the azo dye from diazoated 4-chloro-2-amino-1-phenol-6-sulfonic acid and 1-oxynaphthalene-5-sulfonic acid are used in 1600 parts hot Dissolved water, with 11.4 parts. Chromium oxide (100%) was added in the form of a chromium fluoride solution and the reaction mixture was refluxed for some time. The resulting chromium compound is with after cooling.

    Common salt deposited, filtered, washed with 10% sodium chloride solution and dried.
