und den erhaltenen 1)isazofarbstoi'f mit einen) kupferabgebenden Mittel behandelt.
Im nachfolgenden Beispiel bedeuten die Teile Gewiehtsteile.
<I>Beispiel:</I> 49 Teile des Dipyrazolons der Zusammen- setzun.- (1) werden mit 21 Teilen Natrium- earbonal in un--efähr <B>500</B> Teilen Wasser -e- löst. Die Lösung wird auf <B>0</B> bis<B>50</B> gekühlt und laiil#""zitit mit der Diazoverbindung versetzt,
welehe man dureh Diazotieren von '2'-' Teilen 1,-Czii-1)ox.v-'-'-aniinobeiizol-5-stilloiisäure erhält. .\ach Beendigung der Kiipplun--,), wird die erwärmt, der gebildete Disazofarbstoff daraus mittels Zusatz von Salz abgesehieden, hierauf filfriert und getrocknet.
zn Zur i*'1)ei-fübriin-, in die Kupferkomplex- ##erl)indun- ##ird der Disazofarbstoff bei<B>60</B> bis <B>70"</B> in -uin#--,efähr <B>1000</B> Teilen Wasser -e- löst. Man versetzt die Lösung nach Zugabe von<B>30</B> Teilen kristallisiertem Natriumaeetat mit so viel Teilen einer 10%igen KupTersul- fatlösung,

Der neue, kupferbaltige Disazofarbstoff ist ein braunes Pulver, das sich in Wasser und in konzentrierter Schwefelsäure mit gelber Farbe löst. Er färbt Baumwolle und Fasern aus regenerierter Cellulose in reinen gelben Tönen von ausgezeichneter Licht- -und sehr guten Nasseehtheiten.
Cited latexite for main patent no. <B> 285139. </B> Process for the production of a copper-containing disazo dye. The subject matter of the present patent is (, in a process for the preparation of a copper disazo dye, which is characterized in that one '21 -, mol,
the diazo compound of 1-carboxy-2-aiiiinobenzol-5-sulionsä-lire with <B> 1 </B> moles of the dipyrazolone of the composition
EMI0001.0018
and treated the 1) isazo dye obtained with a) copper-releasing agent.
In the following example the parts mean weight parts.
<I> Example: </I> 49 parts of the dipyrazolone of the composition (1) are dissolved with 21 parts of sodium earbonal in around <B> 500 </B> parts of water. The solution is cooled to <B> 0 </B> to <B> 50 </B> and laiil # "" zitit is mixed with the diazo compound,
which is obtained by diazotizing '2'-' parts 1, -Czii-1) ox.v -'-'- aniinobeiizol-5-stilloic acid. After the end of the tumbling process, the liquid is heated, the disazo dye formed is separated out by adding salt, then filtered and dried.
For the i * '1) egg-fübriin-, in the copper complex- ## Erl) indun- ## the disazo dye at <B> 60 </B> to <B> 70 "</B> in -, approximately 1000 parts of water are dissolved. After adding 30 parts of crystallized sodium acetate, enough parts of a 10% copper sulfate solution are added to the solution.
until you can see free copper (I1) ions in the dye solution. The solution is stirred for some time at <B> 60 </B> to <B> 70 ", then the copper complex compound from Lind is salted and isolated in the usual way.
The new, copper-containing disazo dye is a brown powder that dissolves in water and in concentrated sulfuric acid with a yellow color. It dyes cotton and fibers from regenerated cellulose in pure yellow tones with excellent light and very good wetness properties.
