Description

  

  Verfahren zur Herstellung eines     ehromierbaren    Farbstoffes.    Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines     chromier-          baren    Farbstoffes. Das Verfahren ist da  durch gekennzeichnet, dass man     diazotiertes          5-Nitro    - 2 -     amino    -1-     oxy        -benzol-4-methylsulfon     mit.     1-Phenyl-3-methyl-5-p.#-razolon    vereinigt.  



  Der Chromkomplex des erhaltenen neuen  Farbstoffes stellt ein rotbraunes Pulver dar,  das Wolle aus neutralem oder organisch sau  rem Bade in scharlachroten Tönen von sehr  guter Licht-,     Waseh-    und     Walkechtheit    färbt.       Beispiel:

       Man     diazotiert    23,2 Teile     5-Nitro-2-amino-          1-oxy-benzol-4-methzlsulfon    und kuppelt nach  Neutralisieren mit     Natriumbicarbonat    bei 0  bis 5  mit einer Lösung von 18,3 Teilen     1-Phe-          ny1-3-methyl-5-py        razolon    und 20 Teilen was  serfreien Soda in 200 Teilen Wasser und iso  liert den erhaltenen Farbstoff nach Erwär  men auf 60  durch Zugabe von Kochsalz.  



  Der     Chromkomplex    des Farbstoffes kann       ei-lialteii    werden, indem man 43,9 Teile seines         llononatriumsalzes    in 600 Teilen Wasser mit  110 Teilen einer Lösung von     chromsalicylsau-          rem    Ammonium (entsprechend 4,2 Teilen  Chromoxyd) unter     Rückfluss    einige Stunden  zum Sieden erhitzt. Der     ehromhaltige    Farb  stoff fällt. dabei weitgehend in     kristallinei     Form aus. Er wird nach Erkalten filtriert,  getrocknet und zur Erhöhung der Löslichkeit  mit     101/o    des Gewichtes an wasserfreier Soda  vermischt.



  Process for the production of an honorable dye. The subject of the present patent is a process for the production of a chromable dye. The process is characterized in that diazotized 5-nitro-2-amino-1-oxy-benzene-4-methylsulfone is used. 1-Phenyl-3-methyl-5-p. # - razolone combined.



  The chromium complex of the new dye obtained is a red-brown powder that dyes wool from a neutral or organically acidic bath in scarlet shades of very good fastness to light, washer and milled. Example:

       23.2 parts of 5-nitro-2-amino-1-oxy-benzene-4-methzlsulfone are diazotized and, after neutralization with sodium bicarbonate at 0 to 5, the mixture is coupled with a solution of 18.3 parts of 1-pheny1-3-methyl -5-py razolon and 20 parts of water-free soda in 200 parts of water and iso liert the dye obtained after heating men to 60 by adding sodium chloride.



  The chromium complex of the dye can be isolated by refluxing 43.9 parts of its ionosodium salt in 600 parts of water with 110 parts of a solution of chromium salicylic acid ammonium (corresponding to 4.2 parts of chromium oxide) and refluxing it for a few hours. The dye containing honor falls. largely in crystalline form. After cooling, it is filtered, dried and mixed with 101 / o of the weight of anhydrous soda to increase the solubility.
