Description

  

      Zusatzpateitt    zum Hauptpatent     Nr.   <B>141535.</B>    Verfahren zur Herstellung eines metallhaltigen Farbstoffes.    Es wurde gefunden,     dass    man einen  neuen metallhaltigen Farbstoff erhält, wenn  man den Farbstoff aus     diazotiertem        4-Ghlor-          2   <B>-</B>     amino   <B>- 1 -</B>     phenol    und 2.     3-Oxynaphthoe-          säure    in Gegenwart von Alkalien mit     Chrom-          hydroxyd    behandelt.  



  Der     eUromhaltige    Farbstoff stellt ein  schwärzliches Pulver dar, das sieh in Was  ser mit violetter und in verdünnter Natron  lauge mit     rötlichvioletter    Farbe löst und  Wolle aus sauren Bädern in echten violetten  Tönen färbt.     Zaponlacke    werden ebenfalls in  violetten Tönen gefärbt.

      <I>Beispiel:</I>  <B>7,29</B> Teile des     Natronsalzes    des     Azofarb-          stoffes    aus     4-Chlor-2-amino-l-phenol    und  2.     3-Oxynaphthoesäure    werden in eine     ätzal-          kalische    Chromlösung     (Chromitlösung),    be  stehend aus<B>60</B> Teilen festem     Ätzkali,    450  Teilen Wasser und<B>15,2</B> Teilen     Cr,O"    (in  Form 24<B>%</B>     iger        Hydratpaste)    eingetragen und  unter gutem Rühren so lange erhitzt, bis sich    die Chromverbindung des Farbstoffes gebil  det hat.

       Hernac   <B>'</B> h wird das     Reaktionstgemisch     filtriert und die     Chromverbindung    durch  Neutralisieren der alkalischen Lösung und       Aussalzen    gewonnen.



      Additional patent to main patent no. <B> 141535. </B> Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye is obtained from diazotized 4-chloro-2-amino-1-phenol and 2 3-oxynaphthoic acid treated with chromium hydroxide in the presence of alkalis.



  The eUromium-containing dye is a blackish powder that dissolves in water with violet and in dilute caustic soda with reddish-violet color and dyes wool from acidic baths in real violet tones. Zapon varnishes are also colored in purple tones.

      <I> Example: </I> <B> 7.29 </B> parts of the sodium salt of the azo dye from 4-chloro-2-amino-1-phenol and 2. 3-oxynaphthoic acid are converted into a caustic alkaline Chromium solution (chromite solution), consisting of <B> 60 </B> parts of solid caustic potash, 450 parts of water and <B> 15.2 </B> parts of Cr, O "(in the form of 24 <B>% </ B > iger hydrate paste) and heated with thorough stirring until the chromium compound of the dye has formed.

       Hernac <B> '</B> h the reaction mixture is filtered and the chromium compound is obtained by neutralizing the alkaline solution and salting out.
