Description

  

  Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass     inan        einen    Treuen       Farbstoff    erhält, wenn man die     3-Oxynaph-          thalin-1,8-dikarbonsäure    mit dianotiertem     4,6-          Dinitro-2-amino-l-phenol    kuppelt und     deu    so  erhaltenen Farbstoff mit     Chromfluorid    be  handelt.

   Der neue     Farbstoff    bildet ein schwärz  liches Pulver, löst sich in Wasser unter Zu  satz von Natronlauge mit     bräurilichvioletter     Farbe und erzeugt im Chromdruck auf Baum  wolle sehr echte     rötlichgraue    Töne.    <I>Beispiel:</I>    19,9 Teile 4,6 -     Ditiitr,o    - 2 -     amirro-l-phenol     werden wie üblich dianotiert und in eine  Lösung von 21;6 Teilen     3-Oxy        riaphthalin-          1,8-dikarbonsäureanhydrid,    8 Teilen Natron  lauge und 40 Teilen Soda in 500 Teilen  Wasser eingetragen. Man rührt, bis die     Diazo-          verbindung    verschwunden ist.

   Hierauf salzt  man mit Kochsalz aus und filtriert den aus  geschiedenen     Farbstoff.     



  22,8 Teile des     Dinatriumsalzes    des Farb  stoffes werden in 500 Teilen Wasser gelöst    und mit einer     Fluorehromlösung,    entsprechend  10 Teilen     Cr-203,    versetzt. Man kocht einige  Zeit, zweckmässig in Gegenwart von Glas  pulver, filtriert, löst den Rückstand in     ver-          dünrrter    Natronlauge auf, filtriert, neutrali  siert mit     Mineralsäure    und fällt den     Farbstoff     durch Kochsalz aus.



  Process for the production of a new dye. It has been found that a faithful dye is obtained if the 3-oxynaphthalene-1,8-dicarboxylic acid is coupled with dianotated 4,6-dinitro-2-amino-1-phenol and the dye thus obtained is treated with chromium fluoride .

   The new dye forms a blackish powder, dissolves in water with the addition of caustic soda with a brownish violet color and produces very real reddish-gray tones when printed with chrome on cotton. <I> Example: </I> 19.9 parts of 4,6 - ditiitr, o - 2 - amirro-l-phenol are dianotized as usual and in a solution of 21; 6 parts of 3-oxyriaphthalene-1,8- dicarboxylic anhydride, 8 parts of sodium hydroxide and 40 parts of soda in 500 parts of water. Stir until the diazo compound has disappeared.

   It is then salted out with common salt and the dye which has separated out is filtered off.



  22.8 parts of the disodium salt of the dye are dissolved in 500 parts of water and a fluorine chromium solution, corresponding to 10 parts of Cr-203, is added. The mixture is boiled for some time, expediently in the presence of glass powder, filtered, the residue is dissolved in diluted sodium hydroxide solution, filtered, neutralized with mineral acid and the dye is precipitated with sodium chloride.
