Description
Verfahren zur Herstellung eines neuen liondensationsproduktes. Es wurde gefunden, dass man zu neuen für die Herstellung von Farbstoffen geeig neten Zwischenprodukten gelangt, wenn man Methylenanthron (vergleiche K. H. Meyer, A. 420, 135) seine Derivate oder Substitutions- produkte mit Ausnahme solcher; bei denen ein oder beide Wasserstoffatome der Methy- lengruppe durch einen Phenylrest ersetzt sind, mit sauren Kondensationsmitteln wie Aluminiumchlorid in An- oder Abwesenheit eines Verdünnungsmittels erwärmt.
Während in den deutschen Patentschriften Nr.451907 und 454945 Kondensationspro dukte beschrieben sind, die durch eine Kon densation von Benzylidenanthron beziehungs weise Diphenylmethylerianthron innerhalb des Moleküls unter Beteiligung des einen oder der zwei Phenylreste entstehen, ist der Reak tionsverlauf bei vorliegendem Verfahren völlig verschieden und führt zu Verbindungen einer ganz anders gearteten chemischen Konstitu tion.
Vermutlich treten je zwei Moleküle Methylenanthron unter Bildung eines Deri vates des "5 . 6 . 11 . 12-Dibenzoperylenchi- nons-4.10 zusammen.
Vorliegendes Patent bezieht sich nun auf ein Verfahren zur Herstellung eines neuen Kondensationsproduktes, dadurch gekenn zeichnet, dass man Methylenanthron mit Alu miniumchlorid auf Temperaturen zwischen etwa 100 und 200 C erhitzt.
Die neue Verbindung ist fast farblos und löst sich in Schwefelsäure mit schwach gel ber Farbe, in Alkalien ist sie unlöslich. Sie schmilzt bei Temperaturen über 200 un ter Zersetzung und soll als Zwischenprodukt zur Herstellung von Farbstoffen Verwendung finden. <I>Beispiel:</I> 10 Teile Methylenanthron werden zusam men mit etwa 100 Teilen Aluminiumchlorid und etwa 25 Teilen Kochsalz so lange bei etwa 140 C gerührt, bis in einer Probe kein unverbrauchtes Methylenanthron mehr nach weisbar ist, was näch ungefähr einer Stunde der Fall ist. Man bringt die Schmelze in Eis wasser und trennt den Niederschlag von der Flüssigkeit.
Durch Ausziehen mit wässeriger alkoholischer Lauge kann die Verbindung von etwa noch vorhandenen Verunreinigun gen befreit werden. Aus organischen Lösungs mitteln, z. B. Toluol, lässt sich die Verbin dung in fast farblosen stäbchenförmigen Kristallen erhalten.
Process for the production of a new lion denation product. It has been found that new intermediates suitable for the production of dyes are obtained if methylene anthrone (compare K. H. Meyer, A. 420, 135) is used, its derivatives or substitution products with the exception of such; in which one or both hydrogen atoms of the methyl group have been replaced by a phenyl radical, heated with acidic condensing agents such as aluminum chloride in the presence or absence of a diluent.
While in German patents Nos. 451907 and 454945 condensation products are described that result from a condensation of benzylidene anthrone or diphenylmethylerianthrone within the molecule with the participation of one or two phenyl radicals, the course of the reaction in the present process is completely different and leads to Compounds of a completely different chemical constitution.
Presumably, two molecules of methylene anthrone come together to form a derivative of "5, 6, 11, 12-dibenzoperylene quinone-4.10".
The present patent now relates to a process for the production of a new condensation product, characterized in that methylene anthrone is heated to temperatures between about 100 and 200 C with aluminum chloride.
The new compound is almost colorless and dissolves in sulfuric acid with a pale yellow color; in alkalis it is insoluble. It melts at temperatures above 200 under decomposition and is said to be used as an intermediate in the production of dyes. <I> Example: </I> 10 parts of methylenanthrone are stirred together with about 100 parts of aluminum chloride and about 25 parts of table salt at about 140 ° C until no unused methylenanthrone can be detected in a sample, which is about an hour the case is. The melt is placed in ice water and the precipitate is separated from the liquid.
The connection can be freed of any impurities that may still be present by removing it with aqueous alcoholic lye. From organic solvents, z. B. toluene, the connec tion can be obtained in almost colorless rod-shaped crystals.
