  Verfahren zur Herstellung einer     Clironiverbinduneines        Beizenfarbstoffes.       Es wurde gefunden,     dass    man eine technisch       wertvolle        Clirotnverbinclurig        Herstellen    kann,  wenn     rnan    die     Diazoverbindung    der     1-1linine@-          2-oxynaphtalin-4-sulfosäare        reit        1-Oxy-5    : 8  dichlornaplitalin kuppelt und den so     erhaltenen          Farbstoff    mit chromabgebenden     Mitteln    be  handelt.

   Die so erhaltene     Chromverbindung     stellt einen wertvollen     Säurefarbstoff        dar,    der  Wolle in sehr     egalen,    licht- und     walkecliten     blauen Tönen färbt.  



       Beispiel:          106.5    Teile     1-Oxy-5:8-dicliloi-naphtalin     werden in     überschüssiger    Natronlauge     geli;st     und bei niedriger     Temperatur    mit einer     w;iI.i-          rigen    Suspension von 130 Teilen     diazotierter          1-Amino-2-oxyriaphtaliii-4-sulfosäure    versetzt.

         31.111    rührt, bis die     1)iazove,-bindiingverschwun-          den    ist, verdünnt     finit    Nasser, stellt eben  mineralsauer     finit        Salzsäure    ein     Lind    salzt den  gebildeten     Farbstoff    aus.  



  463 Teile dieses Farbstoffes werden nun  in 1000 Teile einer     wässrigen    Lösung, ent-    haltend     76.;5    Teile Chromoxyd,     22.1,5    Teile       Ätznatron    und 112.5 Teile     Glycei#in    einge  tragen     und    10     Stunden        ain        Rüch$uhkühler          gekocht.    Hierauf     wird    mit der dreifachen       @@'assernienge    verdünnt, das     fr-eigeworderie          .@tzkali    reit     Mineralsäure    eben neutralisiert,

    der     entstandene        chromhaltige        Farbstoff        aus-          ges@iIzen,    filtriert und     guti-ocl@net.  



  Process for the preparation of a clironi compound of a mordant dye. It has been found that a technically valuable compound can be produced if the diazo compound of the 1-1linine @ - 2-oxynaphthalene-4-sulfosäare is coupled with 1-oxy-5: 8 dichloromaplitaline and the dye thus obtained is treated with chromium-releasing agents .

   The chromium compound obtained in this way is a valuable acid dye that dyes wool in very even, light and milled blue tones.



       Example: 106.5 parts of 1-oxy-5: 8-dicliloi-naphthalene are dissolved in excess sodium hydroxide solution and treated at low temperature with an aqueous suspension of 130 parts of diazotized 1-amino-2-oxyriaphtaliii-4- sulfonic acid added.

         31.111 stirs until the 1) iazove, -bindiing has disappeared, dilutes finite water, just adds mineral acid finite hydrochloric acid and saltes out the dye formed.



  463 parts of this dye are then introduced into 1000 parts of an aqueous solution containing 76.5 parts of chromium oxide, 22.1.5 parts of caustic soda and 112.5 parts of glycine and boiled in a cooler for 10 hours. Then it is diluted with threefold @@ 'assernienge, the fr-eigeworderie. @ Tzkali reit mineral acid is neutralized,

    the resulting chromium-containing dye is extracted, filtered and guti-ocl @ net.
