Description

  

      verfahren    zur Herstellung einer Chromverbindung eines     Beizenfürbstoffes.       Es, wurde gefunden, dass man eine tech  nisch wertvolle     Chromvei-biridung        verstellen     kann, wenn man die chlorierte     Diazoverbiri-          dung    der     1-Aniino-2-oxynaphtalin-4-sulfosärire     mit -     1-Oxy-8-cliloriraphtaliii    kuppelt     und    den  so erhaltenen     Farbstoff        finit        ehroinabgebenden     Mitteln behandelt.

   Die so erhaltene Chrom  verbindung stellt einen wertvollen Säurefarb  stoff dar, der Wolle in sehr     egalen,    licht- und       walkechten    blauen     Tönen    färbt.  



  <I>Beispiel:</I>  89 'feile     1-Oxy-8-chlorn.iphtalin    werden  in     überschüssiger    Natronlauge gelöst und bei  niedriger Temperatur mit einer     wäf,)i-igen          Suspension    von 147 Teilen der chlorierten       Diazoverbindung    der     1-Ainino-2-oxynaplitalin-          4-sulfosäure    versetzt. Man rührt, bis die       Diazoverbindung    verschwunden ist, verdünnt  mit Wasser, stellt eben mineralsauer mit  Salzsäure ein und salzt den gebildeten     Farb-          stoff        aus.     



       463    Teile dieses     Farbstoffes    werden nun  in 1000 Teile einer     wässrigen    Lösung, ent-    haltend<B>16,5</B> Teile Chromoxyd,     224,5    Teile       Ätznatron    und 112,5 Teile Glyzerin einge  tragen und 10     Stunden    am     Rückflusskühler     gelocht.

       Hierauf        wird    mit der dreifachen       Wassermenge        verdünnt,    das frei gewordene       Ätzkali        finit        Mineralsäure    eben neutralisiert,  der entstandene     chromhaltige        Farbstoff    aus  gesalzen, filtriert und getrocknet.



      Process for the production of a chromium compound of a pickling agent. It has been found that a technically valuable chromium cladding can be adjusted if the chlorinated diazo compound of 1-aniino-2-oxynaphthalene-4-sulfosary is coupled with - 1-oxy-8-cliloriraphtaliii and the thus obtained Dye treated finite ear-donating agents.

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



  <I> Example: </I> 89 'files 1-oxy-8-chlorine.iphtalin are dissolved in excess sodium hydroxide solution and treated at low temperature with a watery suspension of 147 parts of the chlorinated diazo compound of the 1-ainino- 2-oxynaplitalin-4-sulfonic acid added. The mixture is stirred until the diazo compound has disappeared, diluted with water, adjusted to mineral acid with hydrochloric acid and salted out the dye formed.



       463 parts of this dye are now in 1000 parts of an aqueous solution containing <B> 16.5 </B> parts of chromium oxide, 224.5 parts of caustic soda and 112.5 parts of glycerol and perforated for 10 hours on the reflux condenser.

       Then it is diluted with three times the amount of water, the released caustic potash finite mineral acid is neutralized, the resulting chromium-containing dye is salted, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung einer Chrom verbindung eines Beizenfarbstoffes, dadurch gekennzeichnet, dass die chlorierte Diazovei#- bindung der 1-Amino-2-oxynaphtalin-4-sulfo- sILnrle mit 1-Oxg-8-clilornaphtalin gekuppelt wird und (IM, der so erhaltene Farbstoff mit ehroniabgebenden Mitteln behandelt wird. PATENT CLAIM: Process for the production of a chromium compound of a mordant dye, characterized in that the chlorinated Diazovei # bond of the 1-amino-2-oxynaphthalene-4-sulfosILnrle is coupled with 1-Oxg-8-clilornaphthalene and (IM, der thus obtained dye is treated with Ehroniabendemittel. Die so erhaltene Chromverbindung stellt einen wertvollen Säurefarbstoff dar, der Wolle in sehr egalen lieht- und walkechten blauen Tönen färbt. The chromium compound obtained in this way is a valuable acid dye that dyes wool in very level, lent- and mill-fast blue tones.
