Description

  

  Zusatzpatent zum Hauptpatent     Nr.        1072.04.       Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    ein neuer     Azo-          farbstoff        ei-halten    wird, wenn man<B>1</B>     Mol.        di-          azotierte        4-Methyl-2-amirio-l-phenol-5-sulfo-          säure    auf 2     Mol.        fl-Naphthylamin    einwirken       lässt    und die so erhaltene Doppelverbindung,

    bestehend aus dem     Azofarbstoff    und     fl-Naph-          thylamin,    mit verseifend wirkenden Mitteln  behandelt. Der so erhaltene Farbstoff bildet  ein braunrotes Pulver, löst sich- mit     oranger     Farbe in Wasser, färbt Wolle aus saurem  Bade orange und ist ein wertvolles Ausgangs  material zur Herstellung weiterer Farbstoffe.

           B6ispiel:       <B>203</B> Teile     4-Mothyl-2-ainino-l-phenol-5-          stilfosäure    werden in üblicher Weise     diazo-          tiert;    hierauf wird die mit Soda sorgfältig  neutralisierte     Diazolösung    unter stetem Rüh  ren in eine heisse, wässerige Lösung von<B>357</B>  Teilen     fl-Napthylaininchlorhydrat    gegeben.  Man rührt weiter bei<B>-80-85 0 Q</B> bis die  Kupplung vollzogen ist. Das kristallinisch ab  geschiedene Reaktionsprodukt, bestehend aus  einer Doppelverbindung des o-Aminoazofarb-         stoffes    mit     fl-Naphthylamiii,    wird mit kalter  Natronlauge behandelt.

   Es bildet sich unter  Abspaltung von     P-Naphthylamiii    eine orange  Lösung, aus welcher nach der Filtration der  reine     o-Aminoazofarbstoff    durch     Aussalzen     abgeschieden wird.



  Additional patent to the main patent no. 1072.04. Process for the production of a new azo dye. It has been found that a new azo dye will hold up if <B> 1 </B> mol. Of diazoated 4-methyl-2-aminio-1-phenol-5-sulfonic acid to 2 mol .fl-Naphthylamine can act and the double compound thus obtained,

    consisting of the azo dye and fl-naphthylamine, treated with saponifying agents. The dye obtained in this way forms a brown-red powder, dissolves in water with an orange color, dyes wool from acidic baths orange and is a valuable starting material for the production of other dyes.

           Example: Parts of 4-methyl-2-ainino-1-phenol-5-stilfonic acid are diazotized in the usual way; The diazo solution, carefully neutralized with soda, is then poured into a hot, aqueous solution of <B> 357 </B> parts of fl-naphthylic chlorohydrate with constant stirring. The mixture is stirred at <B> -80-85 0 Q </B> until coupling is complete. The reaction product separated in crystalline form, consisting of a double compound of the o-aminoazo dye with fl-naphthylamine, is treated with cold sodium hydroxide solution.

   An orange solution is formed with elimination of P-naphthylamiii, from which the pure o-aminoazo dye is separated out by salting out after filtration.
