Description

  

      Verfahren    zur     Herstelluub    eines neuen     chronüerbaren        Ortliooxyazofarbstoffes.       Es wurde     gefunden,        class    man durch  Kuppeln     von        cliazotiertem        ö-Nitro-2-amino-          1-oxybenzol        finit        2-Amirionaphtalin-7-sulfo-          säure    einen     neuen        chromierbaren        Orthooxy-          azofarbstoff    Tierstellen kann.

   Dieser Farb  stoff bildet     ein    dunkelviolettes Pulver und  färbt Wolle aus saurem Bad in blauroten  Tönen     an,        welche        beine        Nachchroinieren    in  ein     ausserordentlich    reines und lichtechtes  Grünt von     griter    Walk- und     Pottingechtheit          übergehen.     



  <I>Beispiel:</I>  15,4     kg-        5-Nitro-2-amino-l-ozybenzol    wer  den mit 30     kg-    Salzsäure von 30     %    und 7,2 kg  technischem     Natriumnitrit    wie üblich     diazo-          tiert.    Die     Diazolösiing    lässt man einlaufen  in eine Lösung von 26 kg     2-aminoriaplita-          lin-7-sulfosaiirem    Natrium und 20 kg kristal  lisiertem     N;il.riiiuiacetat.    Die Kupplung ist  nach längerem Rühren bei 30 bis 40<B>11</B> be-    endigt.

   Der Farbstoff wird hernach durch       Solozusatz    als     Natronsalz    in Lösung ge  bracht und in üblicher Weise durch Aus  salzen     abgeschieden.  



      Process for the production of a new chronüerbaren Ortliooxyazo dye. It has been found that by coupling cliazotized δ-nitro-2-amino-1-oxybenzene finite 2-amirionaphthalene-7-sulfonic acid, a new chromable orthooxyazo dye can be produced.

   This dye forms a dark purple powder and dyes wool from an acidic bath in blue-red tones, which, after chroining, turn into an exceptionally pure and lightfast green with great mill and potting fastness.



  <I> Example: </I> 15.4 kg of 5-nitro-2-amino-1-ozybenzene are diazoated as usual with 30 kg of hydrochloric acid of 30% and 7.2 kg of technical grade sodium nitrite. The diazo solution is allowed to run into a solution of 26 kg of 2-aminoriaplita- lin-7-sulfosylated sodium and 20 kg of crystallized nitrous acetate. The coupling is completed after prolonged stirring at 30 to 40 <B> 11 </B>.

   The dye is then brought into solution as a sodium salt by adding it alone and deposited in the usual manner by salts.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen chromiei baren Orthooxyazofa-rbstoffes, da durch gekennzeichnet, dass diazotiertes 5- Nitio-2-arnirio-1.-o_xyberizol mit 2-Amino- naplitalin-\i-srilfosäure gekuppelt wird. PATENT CLAIM: Process for the production of a new chromable orthooxyazofa dye, characterized in that diazotized 5-nitio-2-arnirio-1.-o_xyberizole is coupled with 2-amino-naplitalin- \ i-srilfonic acid. Der erhaltene Fa.rlistoff bildet ein dunkeIviolet- l,es Pulver und- färbt Wolle aus saurem Bad in blauroten Tönen an, welcher beim Nach chromieren in ein ausserordentlich reines und lichtechtes Griin von guter Walk- und Pottingeclitlieit übergehen. The obtained Fa.rlistoff forms a dark violet, it powder and stains wool from an acid bath in bluish-red tones, which, when chromium-plated, turn into an extraordinarily pure and lightfast green of good milled and potting quality.
