Die Umsetzung erfolgt vorteilhaft in einem inerten organischen Lösungsmittel, wobei die Ausgangsstoffe darin gelöst oder auch suspendiert sein können. Man erhitzt vorzugsweise auf 20 bis 110 C wobei sich Chlorwasserstoff abspaltet. Diesen kann man bei erhöhter Temperatur aus dem Reaktionsgefäss entweichen lassen. Im allgemeinen aber ist es zweckmässiger die Reaktion in Gegenwart von säurebindenden Mitteln durchzuführen, wie beispielsweise CaO, Alkalikarbonat oder -bikarbonat, Pyridin, Trialkylamin oder Dialkylanilin. Geeignete Lösungsmittel sind z. B. Benzol, Xylol, Cymol, Diphenyl äther, Tetrahydrofuran, Dioxan. Bedeutet Me ein 2-wertiges Metallion, so führt man vorzugsweise die Verbindung der Formel (I) zuerst in das Alkalimetallsalz über, z.
B. indem man die Verbindung der Formel (I) in Alkohol löst und ein Alkalihydroxid wie NaOH oder KOH zufügt. Anschliessend setzt man dem Reaktionsgemisch ein Me-Salz zu, z. B. das Chlorid, worauf das gewünschte Produkt erhalten wird.
Zur Ausübung des erfindungsgemässen Verfahrens werden die neuen Verbindungen in gegen Licht, Sauerstoff und hitzeempfindliche Substanzen eingearbeitet oder als Schutzschicht auf die zu schützenden Substanzen aufgetragen. Durch ihre stabilisierende Wirkung bewahren die so eingesetzten neuen Verbindungen die empfindlichen Substanzen vor Zerstörung. Besonders zahlreich sind die Anwendungsmöglichkeiten im Kunststoffsektor.
Die Verwendung kommt beispielsweise bei folgenden Kunststoffen in Frage: Celluloseacetat, Celluloseacetobutyrat, Polyäthylen, Polypropylen, Polyvinylchlorid, Polyvinylchlorid-acetat, Polyamide, Polyurethane, Polystyrol, Äthylcellulose, Cellulosenitrat, Polyvinylalkohol, Polycarbonate, Silikonkautschuk, Cellulosepropionat, Melamin Formaldehyd-Harze, Harnstoff-Formaldehyd-Harze, Allylgiessharze, Polymethylmethacrylat, Polyester und Polyacrylnitril, sowie entsprechende Copolymerisate, wie Acrylnitril-Butadien-Styrol-Copolymere. Es können auch Naturstoffe stabilisiert werden, wie beispielsweise Kautschuk. Die zu schützenden Stoffe können in Form von Platten, Stäben, Überzügen, Folien, Filmen, Bändern, Granulaten, Pulvem und in anderen Bearbeitungsformen, oder als Lösungen, Emulsionen oder Dispersionen vorliegen.
Die Einverleibung bzw. die Beschichtung der zu schützenden Materialien erfolgt nach ah sich bekannten Methoden. Ein besonders wichtiges Anwendungsverfahren besteht in der innigen Vermischung eines Kunststoffes, beispielsweise von Polypropylen in Granulafform, mit den neuen Verbindungen, z. B. in einem Kneter, und im sich anschliessenden Extrudieren. Man erhält auf diese Art eine sehr homogene Vermischung, was für einen guten Schutz wichtig ist.
Kunststoffe müssen nicht unbedingt fertig polymerisiert bzw. kondensiert sein bevor die Vermischung mit den neuen Verbindungen erfolgt. Man kann auch Monomere oder Vorpolymerisate bzw. Vorkondensate mit den neuen Stabilisatoren vermischen und erst nachher den Kunststoff in die entgültige Form überführen durch Kondensieren oder Polymerisieren.
Die neuen Stabilisatoren können nicht nur verwendet werden um klare Filme, Kunststoffe und dergleichen zu stabilisieren, sie können auch in undurchsichtigen, halbundurchsichtigen oder durchscheinenden Materialien verwendet werden, deren Oberfläche für Abbau durch ultra-violettes Licht, Luft und Hitze empfindlich ist. Beispiele für solche Materialien sind: geschäumte Kunststoffe, undurchsichtige Filme und Überzüge, undurchsichtige Papiere, durchsichtige und undurchsichtige gefärbte Kunststoffe, fluoreszierende Pigmente, Polituren für Automobile und Möbel, Cremen und Lotionen und dergleichen, gleichgültig ob sie undurchsichtig, klar oder durchscheinend sind.
Das oben beschriebene Verfahren erlaubt die Synthese von sehr verschiedenartigen Varianten von Verbindungen der Formel (I), so dass die Konstitution so gestaltet werden kann, dass die stabilisierende Wirkung in bestimmten Kunststoffen besonders hoch ist.
In den folgenden Beispielen bedeuten die Teile Gewichtsteile und die Prozente Gewichtsprozente. Die Temperaturen sind in Celsiusgraden angegeben. Die angegebenen Strukturen sind durch Mikroanalyse und Spektralanalyse gesichert.
Beispiel 1
Eine Mischung von 17,4 Teilen 1-Phenyl-3-methyl-pyrazolon (5), 11,2 Teilen CaO und 19,6 Teilen 4-tert.-Butyl-benzoylchlorid wird in 100 Teilen Dioxan 30 Minuten lang am Rückfluss gekocht. Der entstandene dicke Brei wird bei Raumtemperatur, unter Rühren, in 200 Teile Wasser gegossen. Die entstandene braune Lösung wird mit verd. HCl angesäuert, der ausgefallene Niederschlag abgesaugt, neutralgewaschen, getrocknet und aus Methanol kristallisiert. Man erhält die Verbindung der Formel
EMI2.1
Beispiel 2
Eine Mischung von 8,26 Teilen 1,3-Diphenyl-pyrazolon (5), 3,92 Teilen CaO und 9,38 Teilen 3,5-Di-tert.-butyl-4-hydroxy-benzoylchlorid werden in 100 Teilen Dioxan 2 Stunden am Rückfluss gekocht. Das Gemisch wird darauf auf Raumtemperatur abgekühlt und in eine Lösung, bestehend aus 50 Teilen 2n HC1 und 100 Teilen Eiswasser, gegossen.
Der ausgefallene Niederschlag wird abgesaugt, neutralgewaschen und aus Methanol kristallisiert.
Man erhält die Verbindung der Formel
EMI2.2
Beispiel 3
3,75 Teile 1 ,3-Diphenyl-4[3' ,5' -di-tert.-butyl-4'-hydroxy] benzoyl-5-hydroxy-pyrazol werden in 60 Teilen Äthanol vorgelegt und auf 45" erwärmt. Bei gleicher Temperatur versetzt man die Mischung mit 4 Teilen 2n KOH-Lösung und 10 Minuten darauf mit einer Lösung von 0,94 Teilen NiCl2-6H2O in 20 Teilen Äthanol. Sofort färbt sich dabei die Lösung grün, und es fällt KC1 aus. Nach 30 Minuten Reaktionszeit wird das KC1 abfiltriert und die grüne Lösung eingedampft. Der feste Rückstand wird mit Wasser gewaschen, abgesaugt und bei 1200 getrocknet.
Man erhält die Verbindung der Formel
EMI2.3
Beispiel 4
34,8 Teile 1-Phenyl-3-methyl-pyrazolon (5) und 13,2 Teile CaO werden bei Raumtemperatur in 40,0 Teile Dioxan vorgelegt. Das Gemisch wird dann in einem Ölbad (80 C) aufgeheizt. Unter Rühren beginnt man bei 75" C Reaktionstemperatur 38,0 Teile Caprinsäurechlorid zuzutropfen. Das Säurechlorid wird innerhalb 45 Minuten zugegeben. Dabei steigt die Temperatur bis auf 95" C, und am Schluss entsteht eine dicke, braune, gut rührbare Paste. Nach Zugabe des Säurechlorids lässt man das Gemisch 1 Stunde bei 80" C weiterreagieren.
Dann kühlt man es ab auf 50 C. Man versetzt nacheinander mit 100 ml Methanol und mit 23,0 Teilen Salzsäure. Nach Zugabe der Letzteren lässt man weitere 30 Minuten rühren; dann versetzt man das Gemisch auf einmal mit 24,8 Teilen Nickelacetat und rührt 30 Minuten lang am Rückfluss (Innentemperatur: 70" C). Der ausgefallene Nickelkomplex wird bei 50 C abgesaugt, mit 1,5 Teilen Wasser halogenfrei gewaschen und anschliessend 2mal mit je 30 Teilen Methanol gewaschen und bei 110 C getrocknet. Arbeitet man unter den oben beschriebenen Bedingungen, so kann das Endprodukt 0 bis 2 Mol Kristallwasser enthalten. Smp. 158-162 C.
Man erhält das Nickelsalz der Verbindung der Formel

Verwendungsbeispiel
Nicht stabilisiertes Polypropylen wird auf einem Walzenstuhl bei 1800 C mit 0,5 % einer Verbindung der Verbindung Nr. 19, Tabelle 2 homogen vermischt und zu Folien von 0,3 mm Dicke verarbeitet. Diese werden im Klimatest nach der Methode von De La Rue auf ihre Beständigkeit geprüft.
Die Prüfung erfolgt bei 40 , bei 75 % relativer Luftfeuchtigkeit, bei starker Lufterneuerung, mit 16 Sunlamps und 16 Blacklamps der Firma Philips. In analoger Weise wurde nicht stabilisiertes und 0,5% der Verbindung Nr. 17 aus Tabelle 2 enthaltendes Polyvinylchlorid im Klimatest geprüft. Die Verbindungen der Formel (I), welche eine sterisch gehinderte phenolische Hydroxylgruppe enthalten, sind auch gute Stabilisatoren für organische Materialien gegen die zersetzende Wirkung von Hitze und Luft (Sauerstoff).

The reaction is advantageously carried out in an inert organic solvent, and the starting materials can be dissolved or also suspended therein. The mixture is preferably heated to 20 to 110 ° C., during which hydrogen chloride is split off. This can be allowed to escape from the reaction vessel at an elevated temperature. In general, however, it is more convenient to carry out the reaction in the presence of acid-binding agents, such as, for example, CaO, alkali metal carbonate or bicarbonate, pyridine, trialkylamine or dialkylaniline. Suitable solvents are e.g. B. benzene, xylene, cymene, diphenyl ether, tetrahydrofuran, dioxane. If Me is a divalent metal ion, the compound of the formula (I) is preferably first converted into the alkali metal salt, e.g.
B. by dissolving the compound of formula (I) in alcohol and adding an alkali hydroxide such as NaOH or KOH. A Me salt is then added to the reaction mixture, e.g. B. the chloride, whereupon the desired product is obtained.
To carry out the process according to the invention, the new compounds are incorporated into substances that are sensitive to light, oxygen and heat, or they are applied as a protective layer to the substances to be protected. Thanks to their stabilizing effect, the new compounds used in this way protect the sensitive substances from destruction. The possible applications in the plastics sector are particularly numerous.
They can be used, for example, with the following plastics: cellulose acetate, cellulose acetobutyrate, polyethylene, polypropylene, polyvinyl chloride, polyvinyl chloride acetate, polyamides, polyurethanes, polystyrene, ethyl cellulose, cellulose nitrate, polyvinyl alcohol, polycarbonates, silicone rubber, formaldehyde cellulose propionate, melamine, formaldehyde Resins, allyl casting resins, polymethyl methacrylate, polyester and polyacrylonitrile, as well as corresponding copolymers such as acrylonitrile-butadiene-styrene copolymers. Natural substances can also be stabilized, such as rubber. The substances to be protected can be in the form of plates, rods, coatings, foils, films, tapes, granules, powders and other processing forms, or as solutions, emulsions or dispersions.
The incorporation or coating of the materials to be protected is carried out according to known methods. A particularly important application method consists in the intimate mixing of a plastic, for example of polypropylene in granule form, with the new compounds, e.g. B. in a kneader, and in the subsequent extrusion. In this way a very homogeneous mixture is obtained, which is important for good protection.
Plastics do not necessarily have to be fully polymerized or condensed before they are mixed with the new compounds. It is also possible to mix monomers or prepolymers or precondensates with the new stabilizers and only afterwards convert the plastic into its final form by condensing or polymerizing.
Not only can the new stabilizers be used to stabilize clear films, plastics and the like, they can also be used in opaque, semi-opaque or translucent materials whose surface is sensitive to degradation by ultra-violet light, air and heat. Examples of such materials are: foamed plastics, opaque films and coatings, opaque papers, clear and opaque colored plastics, fluorescent pigments, polishes for automobiles and furniture, creams and lotions and the like, whether they are opaque, clear or translucent.
The process described above allows the synthesis of very different types of compounds of the formula (I), so that the constitution can be designed so that the stabilizing effect is particularly high in certain plastics.
In the following examples, the parts are parts by weight and the percentages are percentages by weight. The temperatures are given in degrees Celsius. The specified structures are secured by microanalysis and spectral analysis.
