Description

  

  Verfahren zur Herstellung eines     chromierbaren    Farbstoffes.    Gegenstand vorliegenden Patentes ist ein  Verfahren zur     Herstellung    eines     ehromier-          1#aren    Farbstoffes. Das Verfahren ist dadurch  gekennzeichnet, dass man     diazotiertes        2-Amino-          1-oxy-benzol-4-methylsulfon    mit     1-(7-Oxy-          naplithyl)    -     earbamidsäure    -     methylglykolester     vereinigt.  



  Der Chromkomplex des erhaltenen neuen  Farbstoffes stellt ein blauschwarzes Pulver  dar, das Wolle aus neutralem oder schwach  organisch saurem Bade in grauen, hervor  ragend lichtechten und waschechten Tönen  färbt.  



  <I>Beispiel:</I>  Man     diazotiert    18,7 Teile     2-Amino-l-oxy-          benzol-4-met.hyl-sulfon    und kuppelt nach Neu  tralisieren mit     Natriumbicarbonat    bei 0 bis       5     mit einer Lösung von 27,4 Teilen     1-(7-Oxy-          naphthyl)    -     carbamidsäure    -     methylglykolester     7 5 Teilen wasserfreier Soda, 4,2 Teilen     \Ta-          triumhydroxyd    (als     30o/oige    Lösung) in 200  Teilen Wasser.

   Nach Beendigung der     Parb-          stoffbildun,-;    isoliert man den Farbstoff durch       Zugabe    von Kochsalz.    Der Chromkomplex des Farbstoffes kann  erhalten werden, indem man 48,1 Teile seines       1VIononatriumsalzes    in 650 Teilen Wasser mit  110 Teilen einer Lösung von     chromsalicyl-          saurem    Ammonium (entsprechend 4,2 Teilen  Chromoxyd) unter     Rückfluss    zum Sieden er  hitzt, bis die Komplexbildung beendet ist. Es  bildet sich eine dunkelblaue, schleimige Lö  sung, aus der der Chromkomplex durch Zu  gabe von Kochsalz ausgefällt, filtriert und  getrocknet wird.



  Process for the production of a chromable dye. The subject of the present patent is a process for the preparation of an honoring dye. The process is characterized in that diazotized 2-amino-1-oxy-benzene-4-methylsulfone is combined with 1- (7-oxynaplithyl) earbamic acid methylglycol ester.



  The chromium complex of the new dye obtained is a blue-black powder that dyes wool from a neutral or slightly organically acidic bath in gray, exceptionally lightfast and washfast shades.



  <I> Example: </I> 18.7 parts of 2-amino-1-oxybenzene-4-methylsulfone are diazotized and, after neutralization with sodium bicarbonate at 0 to 5, it is coupled with a solution of 27.4 Parts of 1- (7-oxynaphthyl) carbamic acid methylglycol ester 7 5 parts of anhydrous soda, 4.2 parts of sodium hydroxide (as a 30% solution) in 200 parts of water.

   After completion of the formation of parbo-; the dye is isolated by adding sodium chloride. The chromium complex of the dye can be obtained by refluxing 48.1 parts of its 1VIonosodium salt in 650 parts of water with 110 parts of a solution of chromosalicylic acid ammonium (corresponding to 4.2 parts of chromium oxide) until the complex formation is complete . A dark blue, slimy solution forms from which the chromium complex is precipitated by adding sodium chloride, filtered and dried.
