  Additional patent to the main patent no. <B> 291819. </B> Process for the production of a brown, ethylomic dye. The subject of the present patent is a process for the production of a brown paraffin containing Ehrom. The procedure
EMI0001.0006
    Treated with chromium-releasing 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 that dissolves in hot water with a brown color and the wool from neutral. Bath colors in deep brown tones.



  <I> Example: </I> <U> 92.2 </U> parts of 6-chloro - ') - amino-plieiiol-4-methyl-sulfone are added in <B> 150 </B> parts of water <B> 1-7 </B> parts of concentrated hydrochloric acid dissolved, to <B> 50 </B>, ib ("and with occasional addition of ice with <B> 6.9 </B> parts of sodium nitrite 1001 / o (as a 331% solution) added.

   After completion of <B> L 'k3 C </B> Jer diazotization, adding <B> Z, </B> #n of sodium hydrogen carbonate makes it just neutral, then adding <B> 3 </B> parts of sodium hydrogen carbonate züi Lind pours a solution of <B> 18.3 </B> and is characterized by the fact that a <B> kn 3 </B> mixture of equimolecular amounts of the dyes is used

    Parts of 1-phenyl-3-methyl-5-pyrazolone in <B> 300 </B> parts of water and <B> 10,

  5 parts by volume of 10N sodium hydroxide solution. The mixture is stirred without cooling until the coupling is complete, heated to <B> 600 </B> and the precipitated dye (dye I) is filtered off. 18.7 parts of 2-amino phenol-4-nieth, ylsulion are diazotized as described above and neutralized with sodium hydrogen carbonate.

   The diazo compound is poured at <B> 0-30 </B> into a solution of <B> 222.8 </B> parts of carbomethoxyamino-naphthol- <B> (1.7) </B> in 250 parts water, 10.5 parts by volume 10N caustic soda and 15 parts anhydrous sodium carbonate. The coupling is complete after a few hours. The mixture is heated to <B> 700 </B>, the dye, which has partially dissolved, is precipitated by adding sodium chloride and filtered off (dye <B> 11). </B>



  42.9 parts of the monosodium salt of the dye I and 43.7 parts of the monosodium salt of the dye. II are stirred together in 2000 parts of water. 220 parts of a solution of Ehromsalieyl acid ammonium (corresponding to 5.7% Add parts of Cr) and boil for <B> 5 </B> hours.

    A brownish-black <B> oil </B> is released, which solidifies crystalline when it cools. It is filtered off and dried. The new dye is a selective powder that looks brown in hot water
EMI0002.0014
    Treated with chromium-releasing 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 <B> - </B> chromium complex compound that is obtained is a black powder that dissolves and dyes the wool from neutral bath in deep brown tones of very high lightfastness, very, good waseb, fulled and sea water fastness .
