KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gemäfs Patent 116637 gelangt man durch Condensation von Cyclocitral und Aceton mit' Hülfe von alkalischen Agentien zum Jonon (vergl. auch Ber. d. D. ehem. Ges. 33, S. 3722).According to patent 116637 one gets through Condensation of cyclocitral and acetone with the aid of alkaline agents to form the ionone (see also Ber. d. D. formerly Ges. 33, p. 3722).
In gleicher Weise wie das Aceton selbst lassen sich nun auch die homologen und substituirten Acetone mit Cyclocitral condensiren unter Bildung der entsprechenden homologen oder substituirten Jonone. 'In the same way as the acetone itself, the homologous and substituted can now also be used Acetones condense with cyclocitral to form the corresponding homologous or substituted ions. '
Geht man hierbei von einem rohen, aus einem Gemisch von α- und ß-Cyclocitral bestehenden Aldehyd aus, so erhält man ebenso wie nach dem Verfahren des Patentes 75120 Gemische von Isomeren der homologen Jonone. Verwendet man dagegen nur ein einzelnes der beiden isomeren Cyclocitrale, so erhält man die einzelnen entweder der α-Reihe oder der ß-Reihe angehörenden Isomeren der betreffenden homologen Jonone.Assuming this is a raw one, consisting of a mixture of α- and ß-cyclocitral Aldehyde is obtained in the same way as by the process of patent 75120 Mixtures of isomers of the homologous ions. On the other hand, if you only use a single the two isomeric cyclocitrals, one obtains the individual either of the α series or the ß-series isomers of the homologous ionones in question.
Die auf diese Weise zu gewinnenden Homologen des Jonons gehören zwar alle im engeren oder weiteren Sinne zur Klasse der Veilchenriechstoffe, aber in gleicher Weise, wie zwischen dem ß-Jonon und dem 0-Jonon besteht auch zwischen den beiden Isomeren der homologen Jonone ein Unterschied in der Nuance des Geruches. Im allgemeinen haben die Verbindungen der α-Reihe eine mehr süfse, diejenige der ß-Reihe eine mehr herbe Nuance. Man ist nun nicht mehr darauf angewiesen, diejenigen Mischungen der beiden Isomeren zu verwenden, welche bei den verschiedenen Methoden der Inversion von homologen Pseudojononen gerade entstehen, sondern man kann nunmehr jede beliebige zweckentsprechende Mischung herstellen.The homologues of the ion to be obtained in this way all belong in closer detail or broader sense to the class of violet fragrances, but in the same way as between the ß-ionone and the 0-ionone also exist between the two isomers of the homologous Jonone a difference in the nuance of the smell. In general, the connections have the α series a more sweet shade, that of the ß series a more bitter nuance. One is no longer dependent on those mixtures of the two isomers use which in the various methods of inversion of homologous pseudo-jonons just emerge, but you can now produce any suitable mixture.
Die Darstellung des Cyclocitrals und des reinen ß-Cyclocitrals ist in den Patentschriften 108335 ur>d !23747 sowie auch in den Berichten d. D. ehem. Ges. 33, S. 3719 beschrieben. Um aus einem Gemisch von a-Cyclocitral und ß-Cyclocitral reines a-Cyclocitral zu erhalten, kann man z. B. das rohe Cyclocitral mit sauren Reductionsmitteln, wie Natriumamalgam und Essigsäure u. s. w., behandeln. Dabei wird zunächst das ß-Cyclocitral in einen hochsiedenden, wahrscheinlich dimolekularen Körper vom Fp. 129° umgewandelt, während das a-Cyclocitral unverändert bleibt. Letzteres ist durch sein Semicarbazon vom Fp. 206 ° charakterisirt.The representation of the cyclocitral and the pure ß-cyclocitral is in the patents 108335 ur> d ! 23747 as well as in the reports d. D. formerly Ges. 33, p. 3719 described. In order to obtain pure a-cyclocitral from a mixture of a-cyclocitral and ß-cyclocitral, one can, for. B. treat the raw cyclocitral with acidic reducing agents such as sodium amalgam and acetic acid, etc. First, the ß-cyclocitral is converted into a high-boiling, probably dimolecular body with a melting point of 129 °, while the a-cyclocitral remains unchanged. The latter is characterized by its semicarbazone of melting point 206 °.
Beispiel. 50 Theile a-Cyclocitral oder ß-Cyclocitral und 100 Theile Methylethylketon werden mit einer Lösung von 5 Theilen Natrium in wenig Alkohol versetzt. Nachdem die Mischung bei gewöhnlicher Temperatur 10 bis 20 Stunden stehen geblieben, erwärmt man noch 1 bis 5 Stunden auf dem Wasserbade, und zwar beim a-Cyclocitral etwas länger als beim 6-Cyclocitral, bis der Geruch desExample. 50 parts α-cyclocitral or β-cyclocitral and 100 parts methyl ethyl ketone are mixed with a solution of 5 parts of sodium in a little alcohol. After this the mixture was left to stand at ordinary temperature for 10 to 20 hours, heated one to five hours on the water bath, and a little longer with a-cyclocitral than with 6-cyclocitral, until the smell of the
