Description
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.
