Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffe@.       Es wurde gefunden,     dass    man einen neuen,  wertvollen Farbstoff     erbält.    wenn man den       Azofarbstoff,    den man durch Kuppeln von  <B>1</B>     Mol.        diazotierter        Pikraminsäure    mit<B>1</B>     Mol.          1-Naphthyl.tmin-4-sulfosäure    erhalten kann,  mit     Chromformiat    behandelt.

   Der neue Farb  stoff stellt ein schwärzliches Pulver dar, löst  sich im Wasser mit dunkelgrüner Farbe, wel  che sich auf Zusatz von Natronlauge nicht  verändert, und färbt Wolle aus schwefelsaurem  Bade in     dunkelolivegrünen    Tönen mit vor  züglichen Echtheitseigenschaften.

      <I>Beispiel:</I>  48,9 Teile des     Natriumsalzes    des aus     dia-          zotierter        Pikraminsäure    und     1-Naphthylamin-          4-sulfosäure    erhältlichen Farbstoffes werden       .in   <B>900</B> Teilen Wasser kochend gelöst,<B>18</B> Teile       Ohromoxyd    in Form von     Chromformiat    zu  gesetzt und in Gegenwart von Glaspulver    längere. Zeit zurückfliessend gekocht. Durch  Eindampfen und     Aussalzen    wird der neue       ehromhaltige    Farbstoff gewonnen.



  Process for the preparation of a new dye @. It has been found that a new, valuable dye is inherited. when the azo dye, which can be obtained by coupling <B> 1 </B> mol. diazotized picric acid with <B> 1 </B> mol. 1-naphthyl.tmin-4-sulfonic acid, is treated with chromium formate.

   The new dye is a blackish powder, dissolves in water with a dark green color, which does not change when caustic soda is added, and dyes wool from a sulfuric acid bath in dark olive green tones with excellent fastness properties.

      <I> Example: </I> 48.9 parts of the sodium salt of the dye obtainable from diazotized picric acid and 1-naphthylamine-4-sulfonic acid are dissolved in <B> 900 </B> parts of boiling water, <B> 18 parts of Ohromoxide in the form of chromium formate are added and longer in the presence of glass powder. Boiled flowing back in time. The new Ehrom-containing dye is obtained by evaporation and salting out.
