Description
Zusatzpatent zum Hauptpatent Nr. <B>208539-</B> Verfahren zur Herstellung eines Disazofarbstoffes. Gegenstand des Hauptpatentes ist ein -Verfahren zur Herstellung eines Disazofarb- Stoffes, welühes, dadurah gekennzeichnet ist,
dass mantetrazotiertes 4.4-Diaminodiphenyl- amin in alkalischer Lösung mit<B>je 1</B> Mol 1-Ät.'hyla-mino-8-oxynaphthalin-3-6--disulfon- säure und 3-Oxydip-lienylamin vereinigt.
'Wie nun weiter gefunden wurde, erhält man einen Farbstoff von ähnlichen Eigen- sohaAen, wenn man tetrazotiertes, 4.4'-Di- aminodiphenylamin in alkaliseher Lösung mit<B>je 1</B> Mol 1-Butylamino#-8-oxynaphthalin- 3-6-di,sulfo#nsä,u-re und Resorein vereinigt.
<I>Beispiel:</I> <B>19,9</B> Teile 4.4'-Diaminodiphenylamin werden tetrazotiert und<B>37,5</B> Teilen einer alkalischen Lösung von 1-Butylamino-8-oxy- na,phtha,lin-3-6-disulfo,n,säurevereinigt. Nach der Bildung des Monoazofarbstoffes wird eine alkalisehe Lösung von<B>11,0</B> Teilen Ite- sorcin hinzugefügt. Der fertige Disazofarb- stoff wird durch Aussalzen gewannen.
Er fär bt Leder in tiefen grünstichig se,1-iwarzen Tönen.
Die verwendete 1-Butyl#amiuo-8-oxynap-h- thaäin-3-6-dis,ulfensä#u#re wurde durch alka- lisehe, Kondensation von 1-Amino,-8-oxy- na,p'htha,lin-3-6-disulfo,nsäure mit n-Butyl- chlorid gewonnen.
Additional patent to main patent no. <B> 208539- </B> Process for the production of a disazo dye. The subject of the main patent is a process for the production of a disazo color substance, welühes, dadurah is marked,
that tetrazotized 4,4-diaminodiphenylamine is combined in alkaline solution with 1 mole of 1-Ät.'hyla-mino-8-oxynaphthalene-3-6-disulfonic acid and 3-oxydip-lienylamine.
As has now been found, a dye with similar properties is obtained if tetrazotized, 4,4'-di-aminodiphenylamine is mixed in alkaline solution with 1 mole of 1-butylamino -8-oxynaphthalene- 3-6-di, sulfo # nsä, u-re and resorein combined.
<I> Example: </I> <B> 19.9 </B> parts of 4,4'-diaminodiphenylamine are tetrazotized and <B> 37.5 </B> parts of an alkaline solution of 1-butylamino-8-oxy- na, phtha, lin-3-6-disulfo, n, acid combined. After the monoazo dye has formed, an alkaline solution of 11.0 parts of itercin is added. The finished disazo dye is obtained by salting out.
It dyes leather in deep greenish, black tones.
The used 1-butyl # amiuo-8-oxynap-h-thaäin-3-6-dis, ulfensä # u # re was by alkali, condensation of 1-amino, -8-oxy- na, phtha, lin-3-6-disulfonic acid obtained with n-butyl chloride.
