Abstract
Description
- Die Erfindung betrifft wertvolle Metallkomplexe der Formel
-
- Die neuen Metallkomplexe können dadurch hergestellt werden, daß mam 3-Formyl-4-methyl-2,6-dihydroxy-pyridin bzw. ein Alkali- oder Erdalkalisalz davon mit einer ortho-Aminohydroxyverbindung der Formel III
- Als Ausgangsprodukte sind z.B. folgende ortho-Aminohydroxyverbindungen geeignet: ortho-Aminophenol, 2-Amino-4-(oder 3- oder 5- oder 6-)nitrophenol, 2-Amino-4-(oder 3- oder 5-oder 6-)chloro-phenol, 2-Amino-4-(oder 3- oder 5- oder 6-) bromo-phenol, 2-Amino-4-(oder 3- oder 5- oder 6-)cyano- phenol, 2-Amino-4-(oder 3- oder 5- oder 6-)methoxycarbonyl- phenol, 2-Amino-4-(oder 3- oder 5- oder 6-)äthoxycarbonyl- phenol, 2-Amino-4-(oder 3-)butoxycarbonyl-phenol, 2-Amino-4-(oder 5-)trifluormethyl-phenol, 2-Amino-4-(oder 5-)-carbonamido-phenol, 2-Amino-4-(oder 5-)dimethylcarbonamido- phenol, 2-Amino-4-(oder 5-)äthylcarbonamido-phenol,2-Amino-1-naphthol, l-Amino-2-naphthol, 2-Amino-3-naphthol, 2-Amino-4-(oder 5- oder 7-)chloro-1=naphthol, L-Amino-4-(oder 5-, 6- oder 7-)chloro-2-naphthol, 1-Amino-3-(oder 4- oder 8-) nitro-2-naphthol.
- Die Verbindungen der Formel III sind zumeist bekannt bzw. können leicht nach den für die Herstellung von ertho-Aminohydroxyverbindungen bekannten Methoden synthetisiert werden. Das 3-Formyl-4-methyl-2,6-dihydroxy-pyridin und seine Alkali- oder Erdalkalisalze sind neu. Es kann leicht, wie in den nachfolgenden Beispielen beschrieben, hergestellt werden. Von dem 3-Formyl-4-methyl-2,6-dihydroxy-pyridin sind auch andere tautomere Formen, z.B. das 2-Hydroxy-3-formyl-4-methylpyridon-(6), denkbar. Von seinen Salzen simd besonders das Natrium- und Kaliumsalz geeignet. Auch von den Metallkomplexen der allgemeinen Formel I sind noch andere tautomere Formen denkbar. Selbstverständlich wird von der vorliegenden Erfindung jede der möglichen tautomeren Formen umfaßt. Die Umsetzung des 3-Formyl-4-methyl-2,6-dihy- droxy-pyridins oder des entsprechenden Alkali- oder Erdalkalisalzes mit der ortho-Amino-hydroxy-Verbindung wird in geeigneten organischen Lösungsmitteln, beispielsweise Alkoholen mit 1 bis 5 C-Atomen, Glykoläthern. wie z.B. Athylenglykoldimetliyläther, Eisessig, aprotischen Lösungsmitteln. wie z,ld. Toluol, Tetrachlorkohlenstoff, 1,4-Dioxan, Tetrahydrofuran und dergleichen, insbesondere dipolar aprotischen. Lösemitteln, wie z.B. Dimethylformamid, Dimethylsulfoxid, N-Xethylpyrolidon, Tetramethylensulfon und dergleichen oder Wasser oder Gemischen davon, zweckmäßigerweise unter einer Atmosphäre eines Inertgases,wie Stickstoff, bei erhöhten Temperaturen durchgeführt. Als Reaktionstemperaturen können Temperaturen von 60°C bis zur Rückflußtemperatur des Lösungsmittels in Betracht kommen. Die bevorzugten Reaktionstemperaturen betragen von 80 bis 120°C. Die Umsetzung ist normalerweise innerhalb von 2 bis 8 Stunden beendet. Das bei dieser Umsetzung entstandene Azomethin kann ohne Isolierung metallisiert werden, aber auch eine Isolierung des Azomethins vor der Metallisierung ist möglich. Es genügt jedoch im allgemeinen, das Azomethin ohne Isolierung in einem geeigneten Lösungsmittel zu metallisieren. Zu diesem Zweck wird das metallfreie Azomethin in dem zur Azomethinkondensation benutzten Lösungsmittel oder Lösungsmittelgemisch mit einem Metallsalz, vorzugsweise einem Acetat, z.B. Kupfer-II-acetat, unter den gleichen
- Bedingungen wie bei der Azomethinherstellung umgesetzt. Dabei kann es.zweckmäßig sein, den pH-Wert der Lösung zwischen 5 und 6 zu halten, was z.B. durch sukzessive Zugabe von Natriumacetatlösung erfolgen kann.
- Die metallfreien Azomethine sind gelborgangefarbene bis braune Produkte, während die metallhaltigen neuen Metallkomplexe normalerweise gelbstichig-grün bis olivgrün und in den üblichen Lösungsmitteln nur schwer bis sehr schwer löslich sind. Die neuen Metallkomplexe eignen sich daher als farbstarke lösungs- und temperaturbeständige, besonders aber hervorragend licht- und wetterechte Pigmente zur Herstellung von Druckfarben, zum Färben von Kunststoffen in der Masse und als Spinnfarbstoffe und insbesondere zur Herstellung von Lacken und Anstrichstoffen. Aufgrund der guten Echtheiten sind die Pigmente besonders auch in Form ihrer Metallic-Lacke (Aluminium-Lacke) für hochwertige Außen-(Auto-)lacke interessant.
- Die metallfreien und metallhaltigen Azomethine weisen im Pyridinkern eine freie Stellung auf, an die noch Diazokomponenten angekuppelt werden können. So ist es möglich, wertvolle metallfreie und metallhaltige Azomethine herzustellen, die noch eine Azogruppe enthalten.
- Wenn nichts anderes angegeben ist, sind in den nachfolgenden Beispielen Teile in Gewichtsteilen und Temperaturen in Grad Celcius angegeben.
- 21,1 g 2-Hydroxy-3-formyl-4-methylpyridon-(6) als Kaliumsalz werden zusammen mit 14,9 g 4-Chlor-2-aminophenol in 300 ml Eisessig suspendiert und unter Stickstoffatmosphäre 3 Stunden zum Sieden erhitzt (ca. 118°C). Dann werden 10 g Kupfer-II-acetat, gelöst in 300 ml Dimethylformamid, zugegeben, und es wird eine Stunde bei 140°C gehalten. Nach Abkühlen wird abgesaugt, mit Methanol und Wasser gewaschen und getrocknet. Man erhält 33,5 g eines gelbstichig-grünen Metallkomplexes der Formel
- 1200 Teile Wasser werden unter Einleiten von Stickstoff zum Sieden erhitzt und unter Stickstoffeinleitung auf 20°C abgekühlt. Dann gibt man 57,3 Teile 2-Hydroxy-3-formyl-4-methylpyridon-(6) und 34,5 Teile o-Aminophenol zu; erhitzt 4 Stunden am Rückfluß, saugt heiß ab und wäscht mit 1000 Teilen 80°C heißem Wasser. Die erhaltene gelbe Paste des Azomethins gibt man in 6000 Teile Wasser, fügt 60 Teile Kupfer-II-acetat zu und erhitzt 3 1/2 Stunden am Rüekxluß, wobei man durch sukzessive Zugabe von 1100 Teilen 10%iger Natrium-acetat-Lösung den pH-Wert zwischen 5 und 6 hält. Am Ende der Reaktion beträgt der pH-Wert 5,4. Das Produkt wird heiß abgesaugt und mit 1200 Teilen 80°C heißem Wasser gewaschen und bei 40°C im Vakuum getrocknet. Man erhält 44 Teile des Azomethin-Kupfer-Komplexes der Formel
- Ein unter Verwendung des erhaltenenPigments in üblicher Weise hergestellter Autoeinbrennlack zeigte nach dem Einbrennen sehr gute Lichtechtheit, Wetterechtheit und Überspritzechtheit.
-
- Das in den vorstehenden Beispielen als Ausgangsprodukt benutzte 6-Hydroxy-3-formyl-4-methylpyridon- (6) bzw. sein Natriumsalz kann, ausgehend vom 4-Methyl-2,6-dihydroxypyridin, folgendermaßen hergestellt werden:
- 125 Teile 4-Methyl-2,6-dihydroxypyridin in 400 Teilen
- Äthanol werden mit 80 Teilen Natriumacetat, gelöst in 100 Teilen Wasser, und 148 Teilen Chloral in 400 Teilen Wasser zusammengegeben und das Gemisch 8 Stunden bei 20°C gerührt, anschließend läßt man weitere 48 Stunden bei Zimmertemperatur stehen, saugt dann das ausgefallene Produkt ab, wäscht den Rückstand mit Wasser und trocknet bei 30°C im Vakuum. Man erhält so 218 Teile (=80% d.Th.) 3-(β,β,β-Trichlor-α-hydroxy)-äthyl-4-methyl-2,6-dihydroxypyridin, das nach Umkristallisation aus Essigsäureäthylester einen Schmelzpunkt von 1950C besitzt.
- Die Überführung des Kalium- oder Natriumsalzes in die Metallfreie Verbindung geschieht in der Weise, daß 19,1 Teile des erhaltenen Produkts in 200 Teilen eines Gemischs aus 160 Teilen Essigsäure und 40 Teilen Wasser suspendiert werden und das Reaktionsgemisch im Vakuum auf 50 Teile eingeengt wird. Nach Stehenlassen der eingeengten Lösung kristallisiert die metallfreie Verbindung aus. Durch Umlösen und Umkristallisieren aus einem Gemisch aus 160 Teilen Äthanol und 40 Teilen Wasser erhält man das reine 3-Formyl-4-methyl-2,6-di- hydroxypyridin vom Schmelzpunkt 180 bis 182°C.
