Used as starting materials for the reaction with the dicarboxylic acids of the specified type or their esters for example, l-amino-2-oxy-4- or -5-methylbenzene.

Betracht. Nach beendeter Reaktion können die Endstoffe nach üblichen, an sich bekannten Methoden, z. B. durch Sublimieren, Umlösen oder Umkristallisieren, isoliert und gereinigt werden.Consideration. After the reaction has ended, the end products can be prepared by customary methods known per se, e.g. B. by Sublimate, dissolve or recrystallize, isolate and purify.
Die Dehydrierung der Verbindungen der Formel (2) erfolgt zweckmäßig mit Hilfe von milden Oxydationsmitteln. Beispiele dafür sind Quecksilber (Il)-verbindungen wie Mercuriacetat oder Quecksilberoxyd, ferner Kaliumpermanganat, Braunstein, Kupferoxyd, Kupfersulfat, Wasserstoffsuperoxyd, Selendioxyd, Platinoxyd, schließlich oxydierend wirkende, organische Verbindungen wie Nitrobenzol. Als dehydrierende Mittel können auch Katalysatoren, ζ. B. feinverteiltes Nickel, Kupfer, Platin oder Palladium, gegebenenfalls auf Träger aufgebracht, herangezogen werden.The dehydrogenation of the compounds of the formula (2) is expediently carried out with the aid of mild oxidizing agents. Examples are mercury (II) compounds such as mercuric acetate or mercury oxide, also potassium permanganate, Brownstone, copper oxide, copper sulfate, hydrogen peroxide, selenium dioxide, platinum oxide, finally oxidizing organic compounds such as nitrobenzene. Catalysts, ζ. B. finely divided nickel, copper, platinum or palladium, optionally applied to a carrier, are used will.
Die Behandlung mit solchen Mitteln erfolgt vorteilhaft bei erhöhter Temperatur, z. B. zwischen 80 und 15O0C, vorzugsweise in Gegenwart von Lösungsmitteln, z. B. in Eisessig. Mit Mercuriacetat entstehen hierbei im allgemeinen quecksilberhaltige Dehydrierungserzeugnisse, vermutlich Komplexverbindungen, aus denen das Quecksilber in üblicher Weise, z. B. durch Behandeln mit Alkalien, entfernt werden kann.The treatment with such agents is advantageously carried out at an elevated temperature, e.g. B. between 80 and 150 0 C, preferably in the presence of solvents, for. B. in glacial acetic acid. With mercuric acetate this generally results in mercury-containing dehydration products, presumably complex compounds from which the mercury is produced in the usual way, e.g. B. by treating with alkalis, can be removed.
Die nach dem vorliegenden Verfahren erhältlichen, neuen Oxazolverbindungen der Formel (1) sind wertvolle, sehr wirksame, optische Aufhellmittel, die sich zum Aufhellen der verschiedensten Materialien, insbesondere organischer Materialien, eignen. Gute Ergebnisse wurden beispielsweise beim Aufhellen von Lacken, wie Alkydharzlacken oder Nitrocelluloseesterlacken, erzielt. Auch zum Aufhellen von Filmen eignen sich diese Verbindungen.The new oxazole compounds of the formula (1) obtainable by the present process are valuable very effective, optical brightening agents that can be used to brighten a wide variety of materials, in particular organic materials. Good results have been achieved, for example, when lightening paints such as alkyd resin paints or nitrocellulose ester lacquers. These compounds are also suitable for lightening films.

Vor allem sind sie jedoch zum Aufhellen von synthetischen Fasern, z. B. solchen aus Celluloseestern, insbesondere Acetatseide, aus Polyacrylnitril, Polyestern oder Polyvinylchlorid, geeignet. Die Behandlung der optisch aufzuhellenden Materialien mit den neuen Verbindungen kann in üblicher, an sich bekannter Weise erfolgen.Above all, however, they are used for lightening synthetic fibers, e.g. B. those made of cellulose esters, in particular Acetate silk, made of polyacrylonitrile, polyesters or polyvinyl chloride, is suitable. Treatment of the optically brightened Materials with the new compounds can be made in a customary manner known per se.
Die neuen Verbindungen zeichnen sich durch eine hervorragende Aufhellwirkung, insbesondere für die erwähnten Materialien, und durch eine sehr gute Lichttchtheit aus und sind überraschenderweise dem bekannten a,jS-Di-^benzoxazolyl-(2)]-äthylen, dessen Herstellung im Beispiel 5 der deutschen Patentschrift 849 694 beschrieben ist, ganz wesentlich überlegen. In der deutschen Patentschrift 850 008 sind optische Aufhellmittel beschrieben, welche, wie die nach dem vorliegenden Verfahren erhältlichen Verbindungen, ebenfalls zwei Benzoxazolreste enthalten. Diese Reste sind jedoch nicht an den in 2-Stellung befindlichen, sondern an den in 6-Stelhmg befindlichen Ringkohlenstoffatomen miteinander verknüpft, und im Gegensatz zu den nach voiliegendem Verfahren erhältlichen Verbindungen erweisen sie sich als praktisch unbrauchbar zum Aufhellen von Polyesterfasern. Die in der USA.-Patentschritt 2 323 503 beschriebenen Di- bei,zoxazolyl-(2)]-methylenverbindungen sind keine optischen Aufhellmittel.The new compounds are characterized by an excellent lightening effect, especially for the ones mentioned Materials, and by a very good lightfastness and are surprisingly well known a, jS-Di- ^ benzoxazolyl- (2)] - ethylene, its production is described in Example 5 of German Patent 849 694, very much superior. In the German Patent specification 850 008 describes optical brightening agents which, like those according to the present method available compounds, also contain two benzoxazole residues. However, these remnants are not attached to the in the 2-position, but on the in 6-Stelhmg located ring carbon atoms linked together, and in contrast to the following Processes obtainable compounds prove to be practically useless for lightening polyester fibers. The di-, zoxazolyl- (2)] methylene compounds described in US Pat. No. 2,323,503 are not optical brighteners.
