  Additional patent to the main patent no. <B> 291812. </B> Process for the production of a brown, Ehrom-containing dye. The subject of the present patent is a process for the production of a brown, chromium-containing dye. The procedure is
EMI0001.0005
    Treated with Ehroniab, living agents in such quantities that there is at least <B> 1 </B> atom of chromium for every 2 molecules of azo dye.



  The new mixed chromium complex compound obtained is a black powder that dyes wool from a bath in acetic acid in deep brown tones.



  <I> Example: </I> <B> 18.7 </B> parts of 2-am, ino-phenol-4-methylsulion are <B> 150 </B> parts of water with <B> 17 </ B> parts of concentrated hydrochloric acid dissolved, cooled to 511 and mixed with <B> 6.9 </B> parts of sodium nitrite 10011 / o (as 33% i, (), e solution-) with the occasional addition of ice. After completion of the 1) iazotization, sodium bicarbonate is used to make neutral.



       -31an couples this Diazonium.verbindungen with a solution of <B> 18.3 </B> parts 1 - Phenyj-3- characterized in that one Ge mixture of equimolecular amounts of the azo color substances
EMI0001.0032
         metb, y1-5-pyrazolone in 200 parts of water and 20 parts of anhydrous sodium carbonate and isolates the dye after heating to <B> 600 </B> by filtration (Parbstolf <B> 1). </B>



  <B> 18.8 </B> parts of 2-aminophenol-4-siilfamid are dissolved in <B> 150 </B> parts of water with <B> 17 </B> parts of concentrated hydrochloric acid <B> 50 </B> cooled and #diazotized by adding <B> 6.9 </B> parts of sodium nitrite (as a 3311% solution). The diazonium compound is mixed with 27.4 parts of carbomethoxyä.thoxy <B> - </B> amino <B> - </B> naphthol <B> - (1.7)

  </B> Stirred and mixed with <B> 35 </B> parts by volume of 251% ammonia at 211. The mixture is stirred at 0-511 until the coupling has ended and the dyestuff is isolated by filtering (dyestuff II) after adding -NatriLimeblorid.



  39.4 parts of the monosodium salt of Parbs I and 43.8 parts of the monosodium salt of the dye <B> 11 </B> are suspended in 2000 parts of water, mixed with 240 parts of a solution of ammonium ammonium (corresponding to <B> 6, 2 parts Cr) are added and the mixture is heated to boiling for 4 hours.

   A deep brown solution is formed from which the dye is precipitated by adding sodium chloride. It is filtered and dried. The new dye, a black powder, stains
EMI0002.0005
    treated with "Ehroma-giving agents" in such quantities that there are at least <B> 1 </B> atom of chromium for every 2 molecules of azo dye.



  The new mixed chromium complex compound obtained is a black powder of wool. acetic acid bath very evenly in deep brown tones with very good lightfastness.
