Description

  

  Zusatzpatent zum Hauptpatent     Nr.    107204.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    ein neuer     Azo-          farbstoff    erhalten wird, wenn man<B>1</B>     Mol.          diazotierte        4-Chlor-2-ainino-l-phenol-5-sulfo-          säure    auf 2     Mol.        P-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     bratinroteg,    Pulver, löst sich mit     oranger     Farbe in Wasser, färbt Wolle aus saurem  Bade orange     und    ist ein wertvolles Aus  gangsmaterial zur Herstellung weiterer Farb  stoffe.  



  <I>Beispiel:</I>  224,5 Teile     4-Clilor-2-ainino-l-pbenol-5-          sulfosäure,    werden in üblicher Weise     diazo-          tiert;    hierauf wird die mit Soda sorgfältig  neutralisierte     Diazolbsung    unter stetem Rüh  ren in eine heisse, wässerige Lösung von<B>357</B>  Teilen     #-Naphthylaniitichlorhydrat    gegeben.  Man rührt weiter bei<B>80-85 1 C,</B> bis die  Kupplung vollzogen ist. Das kristallinisch ab  geschiedene Reaktionsprodukt, bestehend aus  einer Doppelverbindung des o-Aminoazofai-b-         stoffes    mit     #-Naphthylamin,    wird mit kalter  Natronlauge behandelt.

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



  Additional patent to main patent no. 107204. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if 1 mol of diazotized 4-chloro-2-ainino-1-phenol-5-sulfonic acid is added to 2 mol of p-naphthylamine can act and the double connection thus obtained,

    consisting of the azo dye and fl-naphthylamine, treated with saponifying agents. The dye thus obtained forms a bratinot, 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.



  <I> Example: </I> 224.5 parts of 4-chloro-2-ainino-1-pbenol-5-sulfonic acid are diazotized in the usual way; The diazole solution, carefully neutralized with soda, is then poured into a hot, aqueous solution of <B> 357 </B> parts of # -naphthylaniitichlorohydrate with constant stirring. Stirring is continued at 80-85 ° C. until coupling is complete. The reaction product, which separates out in crystalline form and consists of a double compound of the o-aminoazofa substance with # -naphthylamine, is treated with cold sodium hydroxide solution.

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