Description

  

      Zusatzpatent    zum Hauptpatent Nr. 244603.    Verfahren zur Herstellung eines     Azofarbstoffes.       Es wurde gefunden, dass man zu einem  neuen     Azofarbstoff    gelangt, wenn man den       diazotierten        1VIonoazofa.rbstoff    der     Formel     
EMI0001.0007     
    mit 1- N -     Pherlyl    - (2"-     methyl    - 4' -     phenoxy)-          aminonaphthalin-8=sulfonsäure    kuppelt.  



  Der neue Farbstoff bildet ein blaues Pul  ver mit grünlichem Oberflächenglanz, das  Wolle aus schwach saurem Bade in echten,  blauen Tönen färbt.    <I>Beispiel:</I>  Der durch     Diazotieren    von 35     Teilen.        1-          Aminobenzol-3-sulfonsäure    und     Kuppeln    mit  29 Teilen     1-Aminonaphthalin    erhältliche       Aminoazofarbstoff        wird    wie üblich     diazo-          tiert.    Die     Diazoverbindung    wird mit 200 Tei  len     Methylalkohol        anggeschlämmt    und unter  halb 0 

   C in eine Lösung von 90 Teilen     1-N-          Phenyl    -     (2"-methyl-4'-phenoxy)    -     aminonaph-          thalin-8-sulf        onsäure    in 1000 Teilen Methyl  alkohol eingetragen. Nacheinigen Stunden    wird der gebildete Farbstoff isoliert, in ver  dünnter     Natriumcarbonatlösung    gelöst und in  der Wärme mit     Natriumchloridlösung    gefällt,  abgesaugt und mit verdünnter Natrium  chloridlösung gewaschen. Der getrocknete  Farbstoff ist ein blaues Pulver mit grün  lichem Oberflächenglanz, das sich in Wasser  mit blauer Farbe löst. Der Farbstoff färbt  Wolle aus     essigsaurem    Bade blau.



      Additional patent to main patent No. 244603. Process for the production of an azo dye. It has been found that a new azo dye is obtained if one uses the diazotized 1Vionoazofa dye of the formula
EMI0001.0007
    with 1- N - pherlyl - (2 "- methyl - 4 '- phenoxy) - aminonaphthalene-8 = sulfonic acid.



  The new dye forms a blue powder with a greenish surface sheen that dyes wool from a weakly acidic bath in real blue tones. <I> Example: </I> The one made by diazotizing 35 parts. 1- aminobenzene-3-sulfonic acid and coupling with 29 parts of 1-aminonaphthalene aminoazo dye is diazo- as usual. The diazo compound is slurried with 200 Tei len methyl alcohol and below half zero

   C in a solution of 90 parts of 1-N-phenyl - (2 "-methyl-4'-phenoxy) - aminonaphthalene-8-sulfonic acid in 1000 parts of methyl alcohol. After a few hours, the dye formed is isolated, in ver dissolved in a thin sodium carbonate solution and precipitated with sodium chloride solution while warm, suction filtered and washed with dilute sodium chloride solution. The dried dye is a blue powder with a greenish surface luster that dissolves in water with a blue color. The dye dyes wool from acetic acid bath blue.
