Nach Bertram und Gildemeister (Journ. f. prakt. Chemie [2] 49, 193) und Stephan (Journ. f. prakt. Chemie [2] 58, 109) geht Linalool durch Einwirkung von organischen Säuren, z. B. Essigsäure, bei Gegenwart von Mineralsäuren (Schwefelsäure) oder von organischen Säureanhydriden, z. B. Essigsäureanhydrid, und Verseifung in Geraniol und bei 35° schmelzendes d-Terpineol über.According to Bertram and Gildemeister (Journ. F. Prakt. Chemistry [2] 49, 193) and Stephan (Journ. F. Prakt. Chemie [2] 58, 109) linalool goes through the action of organic Acids, e.g. B. acetic acid, in the presence of mineral acids (sulfuric acid) or of organic acid anhydrides, e.g. B. acetic anhydride, and saponification in geraniol and d-terpineol melting at 35 ° over.
Dieses Geraniol läßt sich nach Stephan (a. a. O.) durch Behandeln mit gepulvertem wasserfreiem Chlorcalcium und Auswaschen der entstandenen Geraniolchlorcalciumverbindung mit wasserfreiem Äther isolieren.According to Stephan (op. Cit.), This geraniol can be treated with powdered anhydrous calcium chloride and washing out the resulting geraniol calcium chloride compound isolate with anhydrous ether.
Auch das von Barbier (Compt. rend. 116, 1200; 117, 120) aus Linalool in der vorstehend angegebenen Weise erhaltene und zuerst als neuer Alkohol C10 HIS O angesprochene »Licarhodol« ist nach vorgenannten Forschern ein Gemenge von Geraniol und Terpineol.According to the aforementioned researchers, the "Licarhodol" obtained from linalool in the manner indicated above and initially referred to as the new alcohol C 10 H IS O by Barbier (Compt. Rend. 116, 1200; 117, 120) is a mixture of geraniol and terpineol.
Es wurde nun gefunden, daß aus Linalool sowohl durch Essigsäure und Schwefelsäure wie auch durch Essigsäureanhydrid der gemaß Patent 150595 erhältliche Terpenalkohol C10H18O, der den Namen Nerol erhalten hat, gewonnen wird. It has now been found that the terpene alcohol C 10 H 18 O, which is obtainable according to patent 150595 and which has been given the name nerol, is obtained from linalool both by acetic acid and sulfuric acid and by acetic anhydride.
Die Darstellung des Nerols aus Linalool wird durch folgende Beispiele erläutert:The preparation of nerol from linalool is illustrated by the following examples:
2 kg Linalool (oder Coriandrol) werden2 kg of Linalool (or Coriandrol) should be used
in 5 kg Eisessig gelöst und bei guter Kühlung allmählich mit einer Lösung von 30 g konzentrierter Schwefelsäure in 100 g Eisessig unter Umrühren versetzt. Nach zweitägigem Stehen bei Zimmertemperatur wird das Reaktionsprodukt mit Wasser ausgefällt und das ab-' gehobene öl mit einer Lösung von 500 g Ätzkali in 3 kg 9Oprozentigem Alkohol bei gewöhnlicher Temperatur oder durch Erwärmung auf dem Wasserbade verseift. Das verseifte und gut gewaschene Öl wird weiter mit Dampf rektifiziert und dann im Vakuum in der Weise fraktioniert, daß die bei der Einwirkung der Eisessig-Schwefelsäure entstandenen Terpene und unverändertes Linalool in der Hauptsache entfernt werden. Die höher siedenden Anteile, welche vorwiegend aus Terpineol, Geraniol und Nerol bestehen, (etwa 50 Prozent des verseiften Öles) werden mit gleichen Teilen Phtalsäureanhydrid und Benzol etwa 1 1J2 Stunden auf dem Wasserbade am Rückflußkühler gekocht. Hierbei gehen nur die primären Alkohole in saure Phtalsäureester über, während andere Alkohole nicht reagieren. Aus dem Reaktionsgemisch entfernt man das unangegriffene Anhydrid durch Ausfrierenlassen unter Zugabe von I bis 2 Teilen Petroläther und Absaugen und befreit das Filtrat von Benzol und Petroläther durch Destillation. Die zurückbleibenden sauren Phtalsäureester, welche eine dickflüssige Masse bilden, werden in verdünnter Sodalösung gelöst und so lange mit Äther ausgeschüttelt, bis die Extrakte geruchlos geworden sind. Alsdann fällt man die Lösung der phtalestersauren Natronsalze mit verdünnter Schwefelsäure, zieht die freien Phtalestersauren mit Äther aus und verseift sie mit alkoholischer Kalilauge bei . gewöhnlicher Temperatur oderdissolved in 5 kg of glacial acetic acid and, with good cooling, a solution of 30 g of concentrated sulfuric acid in 100 g of glacial acetic acid is gradually added with stirring. After standing for two days at room temperature, the reaction product is precipitated with water and the oil lifted off is saponified with a solution of 500 g of caustic potash in 3 kg of 90 percent alcohol at ordinary temperature or by heating on a water bath. The saponified and well washed oil is further rectified with steam and then fractionated in vacuo in such a way that the terpenes and unchanged linalool formed by the action of glacial acetic acid are mainly removed. The higher boiling fractions, which consist mainly of terpineol, geraniol and nerol (approximately 50 percent of the saponified oil) are boiled with equal parts of phthalic anhydride and benzene about 1 1 J 2 hours on a water bath under reflux. Only the primary alcohols are converted into acidic phthalic acid esters, while other alcohols do not react. The unaffected anhydride is removed from the reaction mixture by freezing out with the addition of 1 to 2 parts of petroleum ether and suction, and the filtrate is freed from benzene and petroleum ether by distillation. The remaining acidic phthalic acid esters, which form a viscous mass, are dissolved in dilute soda solution and shaken out with ether until the extracts have become odorless. The solution of the sodium phthalates is then precipitated with dilute sulfuric acid, the free phthalates are extracted with ether and saponified with alcoholic potassium hydroxide. ordinary temperature or
