Der neue Farbstoff stellt ein gelbbraiuies Pulver dar, welches sich in Wasser mit gelb brauner Farbe leicht löst. und anodiscli oxydiertes Aluminium in goldgelben Tönen 1-on sehr guter Lichtechtheit. färbt.
Der beim vorliegenden Verfahren als Aus- @,angsstoff dienende, der obigen Formel ent sprechende Monoazofarbstoff kann hergestellt ,.verden, indem man diazotierte 2-Amino-l- oxylienzol-4,6-disulfonsäure mit 1-Phenyl-3- methyl-5-pyrazolon vereinigt.
Die Diazotierung der 2-Amino-l-oxybenzol- -,6-disulfonsäure kann in üblicher, an sich bekannter Weise, z. B. mit Hilfe von Nat.rium- nitrit. und Salzsäure, erfolgen. Die Kupplung (Ier Diazoverbindung mit dem 1-Phenyl-3- in(-#thyl-5-pyrazolon erfolgt zweckmässig in rlhalischem Medium.
Die C berführung des Farbstoffes in dessen Kupferverbindung kann mit dem Rohprodukt. _@esehehen, wie es im Kupplungsgemisch vor- liegt. Sie kann auch mit dem filtrierten oder mit dem durch Umlösen gereinigten Farbstoff geschehen.
Als kupferabgebende Mittel können beim vorliegenden Verfahren vor allem die ein fachen Kupfersalze, wie Kupfersulfate oder Kupferacetat, in Betracht kommen. Auch komplexe Kupferverbindungen können für diesen Zweck verwendet werden, z. B. solche, welche das Kupfer im Anion komplex gebun den enthalten, z. B. komplexe Kupferverbin dungen der Alkalisalze aliphatischer Amino- earbonsäuren oder Oxycarbonsäuren wie des Glykokolls, der Milchsäure und vor allem der Weinsäure, wie Natriumkupfertartrat.
Die Behandlung mit den kupferabgeben den Mitteln kann nach an sieh bekannten Methoden erfolgen, z. B. durch Erwärmen auf Temperaturen zwischen 50 und 150 im offe nen Gefäss, z. B. unter Rückflusskühlung oder gegebenenfalls im geschlossenen Gefäss unter Druck, wobei die pn-Verhältnisse durch die Natur des gewählten Metallisierungsverfah- rens gegeben sind; z.
B. eine saure Kupferung mit Kupfersulfat, eine alkalische Kupferung mit Kupfertetramminsulfat. Gewünschten falls können bei der Metallisierung weitere Stoffe, wie z. B. Alkohol, zugesetzt werden. <I>Beispiel:</I> -17,6 Teile Natriumsalz des Farbstoffes aus diazotierter 2-Amino-l-oxybenzol-4,6-disulfon- säure und 1-Phenyl-3-methyl-5-pyrazolon wer- den in 150 Teilen Wasser bei 70 bis 75 gelöst.
und die erhaltene Lösung mit 120 Teilen einer 7,8 Teile Kupfer enthaltenden Kupfersulfat lösung versetzt. Man rührt 30 Minuten bei 70 bis 75 und filtriert dann den vollständig abgeschiedenen Kupferkomplex ab. Der erhal tene kupferhaltige Farbstoff wird mit 40 Teilen Wasser und 30 Teilen einer 30 o/oigen Natriumhydroxy dlösung vermengt und die so erhaltene Paste im Vakuum getrocknet.
Process for the preparation of a metal-containing monoazo dye. It has been found that a new, valuable metal-containing monoazo dye is obtained if one uses the monoazo dye of the formula
EMI0001.0010
lets copper releasing agents act.
The new dye is a yellow-brown powder that easily dissolves in water with a yellow-brown color. and anodized aluminum in golden yellow tones 1-one very good lightfastness. colors.
The monoazo dyestuff, which serves as the starting material in the present process and corresponds to the above formula, can be prepared, .verden, by reacting diazotized 2-amino-oxylienzol-4,6-disulfonic acid with 1-phenyl-3-methyl-5 -pyrazolone combined.
The diazotization of 2-amino-1-oxybenzene-, 6-disulfonic acid can be carried out in a conventional manner known per se, for. B. with the help of sodium nitrite. and hydrochloric acid. The coupling of the diazo compound with the 1-phenyl-3-yn (- #ethyl-5-pyrazolone is expediently carried out in a rhhalic medium.
The conversion of the dye into its copper compound can be carried out with the crude product. _ @ esehehen as it is in the clutch mixture. It can also be done with the filtered dye or with the dye purified by dissolving.
The copper-releasing agents used in the present process are, in particular, simple copper salts, such as copper sulfates or copper acetate. Complex copper compounds can also be used for this purpose, e.g. B. those which contain the copper in the anion complex gebun the, z. B. complex copper compounds of the alkali metal salts of aliphatic amino acids or oxycarboxylic acids such as glycocolla, lactic acid and especially tartaric acid such as sodium copper tartrate.
The treatment with the copper donating agents can be done by methods known per se, for. B. by heating to temperatures between 50 and 150 in the open vessel, z. B. under reflux cooling or, if necessary, in a closed vessel under pressure, the pn ratios being given by the nature of the chosen metallization process; z.
B. an acid copper plating with copper sulfate, an alkaline copper plating with copper tetrammine sulfate. If desired, other substances, such as. B. alcohol can be added. <I> Example: </I> -17.6 parts of the sodium salt of the dye from diazotized 2-amino-1-oxybenzene-4,6-disulfonic acid and 1-phenyl-3-methyl-5-pyrazolone are in 150 parts of water at 70 to 75 dissolved.
and 120 parts of a copper sulfate solution containing 7.8 parts of copper are added to the resulting solution. The mixture is stirred for 30 minutes at 70 to 75 and then the completely deposited copper complex is filtered off. The copper-containing dye obtained is mixed with 40 parts of water and 30 parts of a 30% strength sodium hydroxide solution and the paste thus obtained is dried in vacuo.
