Zusatzpatent zum Hauptpatent Nr. 307327. Verfahren zur Herstellung eines wasserlöslichen<B>und</B> beizenziehenden Azophthalocyaninfarbstofes. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines wasserlösli- cüen und beizenziehenden Azophthalocy anin- farbstoffes, welches dadurch gekennzeichnet ist, dass man 1 Mol Nickelpllthalocyanin-3,3', 3",
3"'-tetrasltlfochlorid mit 1 Mol 4-Amino- 2-chlor-4'-oxy-1,1'-azobenzol-5'-carbonsäure in Gegenwart einer Mineralsäure neutralisieren den Substanz zur Umsetzung bringt. Im übri gen wird man sich von den im Hauptpatent memachten Ausführungen leiten lassen.
Das nachstehende Beispiel erläutert das neue Verfahren. Die angegebenen Teile be deuten Gewichtsteile.
Beispiel: 29 Teile (3/10o 12o1) Nickelphthalocyanin- 3,3"' - t.etrasulfochlorid, erhalten durch Einwirkung von Chlorsulfonsäure auf Nik- helphthaloey anin, werden auf Eis ausgeladen und (las abgetrennte Reaktionsprodukt als feuchte Paste mit.
150 Teilen zerkleinertem Isis vermischt und eine Lösung von 9,4 Tei len (a/100 31o1) des Natriumsalzes der 4- Aniino-''-chlor-4'-oxy-1,1'- azobenzol-5'-ca.rbon- säure in 100 Teilen Wasser und 15 Teilen Cal.ciumcarbonat zugegeben.
Man lässt wäh rend 24 Stunden bei 0-5 C rühren, stellt das Reaktionsgemisch mit Natriumcarbonat sehwach alkalisch, erwärmt auf 60 C, filtriert vom Calciumcarbonat ab und isoliert den Farbstoff durch Aussalzen mit Natriumchlo- rid.
Der so erhaltene Farbstoff stellt ein dun kelblaugraues Pulver dar, das sich in Wasser mit grünstickig blauer und in konz. Schwefel säure mit gelbbrauner Farbe löst. Im Chrom druck auf Baumwolle liefert der Farbstoff blaugrüne Farbtöne von guten Echtheits eigenschaften.
Additional patent to main patent no. 307327. Process for the production of a water-soluble <B> and </B> associated azophthalocyanine dye. The present invention relates to a process for the production of a water-soluble azophthalocyanine dye, which is characterized in that 1 mol of nickel-3,3 ', 3 ",
3 "'- tetrasltlfochlorid with 1 mole of 4-amino-2-chloro-4'-oxy-1,1'-azobenzene-5'-carboxylic acid in the presence of a mineral acid will neutralize the substance be guided by the statements made in the main patent.
The following example illustrates the new procedure. The parts indicated are parts by weight.
Example: 29 parts (3 / 10o 12o1) nickel phthalocyanine 3.3 "'- tetrasulphochloride, obtained by the action of chlorosulphonic acid on nickel phthalocyanine, are unloaded onto ice and the separated reaction product as a moist paste.
150 parts of crushed Isis mixed and a solution of 9.4 Tei len (a / 100 31o1) of the sodium salt of 4-Aniino -''-chloro-4'-oxy-1,1'-azobenzene-5'-carbon - Acid in 100 parts of water and 15 parts of calcium carbonate were added.
The mixture is stirred for 24 hours at 0-5 ° C., the reaction mixture is made slightly alkaline with sodium carbonate, heated to 60 ° C., calcium carbonate is filtered off and the dye is isolated by salting out with sodium chloride.
The dye obtained in this way is a dark blue-gray powder that turns greenish blue in water and in conc. Sulfuric acid dissolves with a yellow-brown color. In chrome printing on cotton, the dye provides blue-green shades with good fastness properties.
