  Zusatzpatent zum Hauptpatent     Nr.    117996.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass        man    einen       zn     neuen Farbstoff erhält, wenn man das       o-Aminophenol        diazotiert,    hierauf mit     1-(3'-          Sul        famido)   <B>-</B>     phenyl   <B>- 5 -</B>     pyrazolon   <B>- 3 -</B>     karbon-.          .,

  äure    kuppelt und den so erhaltenen Farbstoff  mit     Alkaliehromiten    behandelt. Der neue  Farbstoff bildet ein     orangebraunes    Pulver,  löst sieh in -Wasser und in verdünnter Natron  lauge mit     oranger,    in konzentrierter     Schwe-          z#          felsäure    mit gelber Farbe und färbt Wolle  aus saurem Bade in orangen Tönen mit vor  züglichen     Eigensehaften.       <I>Beispiel<B>:

  </B></I>  <B>10,9</B> Teile     o-Aminophenol    werden in<B>üb-</B>  licher Weise mit<B>6,9</B> Teilen     Natriumnitrit          di!izotiert.    Die     Diazolbsung        lässt    man in eine  eiskalte Lösung von<B>28,3</B> Teilen     1-(3"-Sul-          f,iinido)-phenyl   <B>- 5 -</B>     pyrazolon   <B>-3 -</B>     karbonsäure          und   <B>30</B> Teilen Soda in<B>250</B> Teilen Wasser unter  Rühren einfliessen.

   Die Reaktionsmasse wird  nach vollendeter Kupplung auf<B>50 '</B> ange  wärmt und der Farbstoff mit Kochsalz     aus-          gesalzen    und wie üblich isoliert.    42,9 Teil des so erhaltenen Farbstoffes  werden in eine kochende Lösung enthaltend  <B>8,5</B> Teile     Cr.-#0"    200 Teile Wasser,<B>28</B> Teile       Ätzkali    und<B>10</B> Teile Glyzerin eingetragen  und längere Zeit gekocht. Nach Verdünnen  mit 200 Teilen Wasser wird filtriert und der  neue Farbstoff aus dem Filtrat durch Neu  tralisieren und     Aussalzen    isoliert.



  Additional patent to main patent no. 117996. Process for the production of a new dye. It has been found that a new dye is obtained if the o-aminophenol is diazotized, then with 1- (3'-sulfamido) - phenyl - 5 - pyrazolon <B> - 3 - </B> carbon-. .,

  acid couples and the dye thus obtained is treated with alkali chromites. The new dye forms an orange-brown powder, dissolves in water and in dilute caustic soda with orange, in concentrated sulfuric acid with yellow color and dyes wool from acid baths in orange tones with excellent properties. <I> Example <B>:

  </B> </I> <B> 10.9 </B> parts of o-aminophenol are <B> usual </B> with <B> 6.9 </B> parts of sodium nitrite di! listed. The diazole solution is left in an ice-cold solution of 28.3 parts of 1- (3 "-Sulf, iinido) phenyl -5 - pyrazolone -3 - Pour in carbonic acid and <B> 30 </B> parts of soda in <B> 250 </B> parts of water while stirring.

   After coupling is complete, the reaction mass is heated to <B> 50 '</B> and the dye is salted out with sodium chloride and isolated as usual. 42.9 parts of the dye thus obtained are poured into a boiling solution containing <B> 8.5 </B> parts of Cr .- # 0 "200 parts of water, <B> 28 </B> parts of caustic potash and <B> 10 </B> Parts of glycerine added and boiled for a long time.After dilution with 200 parts of water, it is filtered and the new dye is isolated from the filtrate by neutralization and salting out.
