Description
Zusatzpatent zum Hauptpatent Nr. 138024. Verfahren zür Herstellung eines metallhaltigen Azofarbstoffes. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man ;
den ehromhaltigen Farbstoff, der durch Behandlung des Azofa.rbstoff(,-s, aus der nitrierten 1-Diazo-2-oxynaplitlialin-4- su-Ifos#Lure und a-Naplitliol mit Chromformiat in der Whirme und in Gegenwart von Na- triumacetat entsteht, mit Kupferverbindun- -en, die durch Einwirkung von ÄtzaJkalien auf Kupfersalze in Gegenwart von Glyzerin entstehen, behandelt.
Der neue Farbstoff ist in Wasser mit viol,ett,se,liwarzer, in<B>10</B> %icer Natronlauge mit rötlich braunvioletter und in konzen- trierter Schwefelsäure mit blauer Farbe lös lich. Er färbt Wolle und Seide in schwarzen Tönen an.
<I>Beispiel:</I> <B>50</B> Teile des Farbstoffes aus der nitrier ten 1.-Diazo#-,-)-oxynaphthalin-4-sulfos#Lure und a-NLapht,liol -werden, in<B>600</B> Teilen Wasser un ter Zusatz von<B>7</B> Teilen Natrontauge <B>30<I>'</I></B><I> B6</I> ge n löst und mit<B>15</B> Teilen krist, Natriumacetat, sowie einer Lösung von 21 Teilen Chrom- formiat, enthaltend 40<B>%</B> Cr#A,1, in<B>100</B> Teilen Wasser versetzt. Man hocht drei Stunden rück fliessend und filtriert.
Eine<B>50</B> Teilen des chromhaltigen Farb stoffes entsprechende Mengen dieser Lösung wird bei<B>30 '</B> mit, einer kupferhaltigen Lösung aus<B>2,5</B> Teilen Kupfersulfat krist., <B>15</B> Teilen Glyzerin,<B>5 5</B> Teilen Natronlauge<B>3,0 '</B> B6 und 400 Teilen Wasser versetzt. Man lässt über Nachtstehen, bringt sodann die teilweise un- löslich.a.,b#ges#r,hieid,en,eCr-Cu-Verbindung durch Zugabe von<B>30</B> Teilen Essigsäure und<B>Ei</B> r- wärmenauf 40<B>'</B> in Lösung, filtriert salzt aus und trocknet wie übheh.
Additional patent to main patent No. 138024. Process for the production of a metal-containing azo dye. It has been found that a new metal-containing dye is obtained if one;
the Ehrom-containing dye, which by treatment of the azo-dye (, - s, from the nitrated 1-diazo-2-oxynaplitlialin-4-su-Ifos # lure and a-naplitliol with chromium formate in the whirlpool and in the presence of sodium acetate arises, treated with copper compounds which are formed by the action of caustic substances on copper salts in the presence of glycerine.
The new dye is soluble in water with violet, ett, se, liwarzer, in <B> 10 </B>% sodium hydroxide solution with reddish brownish-violet and in concentrated sulfuric acid with blue color. He dyes wool and silk in black tones.
<I> Example: </I> <B> 50 </B> parts of the dye from the nitrated 1.-diazo # -, -) - oxynaphthalene-4-sulfos # lure and a-NLapht, liol - become, in <B> 600 </B> parts of water with the addition of <B> 7 </B> parts of sodium hydroxide solution <B>30<I>'</I></B> <I> B6 </I> ge n dissolves and with <B> 15 </B> parts of crystal, sodium acetate, and a solution of 21 parts of chromium formate, containing 40 <B>% </B> Cr # A, 1, in <B> 100 </ B> parts of water added. The mixture is refluxed for three hours and filtered.
An amount of this solution corresponding to <B> 50 </B> parts of the chromium-containing dye is mixed with <B> 30 '</B>, a copper-containing solution of <B> 2.5 </B> parts of crystalline copper sulfate., <B> 15 </B> parts of glycerine, <B> 5 5 </B> parts of sodium hydroxide solution <B> 3.0 '</B> B6 and 400 parts of water are added. It is left to stand overnight, then the partially insoluble a., B # ges # r, hieid, en, eCr-Cu compound is added by adding <B> 30 </B> parts of acetic acid and <B> egg < / B> r- warm to 40 <B> '</B> in solution, filter, salt out and dry as usual.
