Verfahren zur Herstellung von terpenfreien ätherischen Ölen.
Die natürlichen ätherischen Öle stellen bekanntermassen Gemenge von Aldehyden, Alkoholen, Ketonen und Estern mit Terpen-Kohlenwasserstoffen dar. Wirksame Bestandteile sind davon fast ausnahmslos die erstgenannten und es sind seit langem sogenannte terpenfreie Öle im Handel, welche die wirksamen. Bestandteile in konzentrierter Form enthalten sollen. 1'ber die bei der Deterpenisierung der ätherischen Öle angewandten Verfahren ist bisher wenig bekannt geworden. Aus den vorliegenden diirftigen Angaben geht bloss hervor, dass die mehrfache Anwendung der fraktionierten Vakuumdestillation in Verbindung mit der Ausnutzung der geringeren Löslichkeit der Terpene in verdünntem Alkohol bei der Deterpenisierung in Anwendung kommen. (Siehe Böeker Journal für praktische Chemie (2) 89, S. 199).
Diese Methoden haben jedoch alle den Nachteil der Umständlichkeit infolge der Notwendigkeit.
EMI1.1
genügend vollständig ist.
Es wurde nun gefunden. dass bei der Anwendung einer methylalkoholischen Chlorkalziumlösung die Abseheidung der Terpene aus ätherischen Ölen viel leichter vor sich geht.
Vermischt man z. B. die Fraktion vom Siedepunkt 100 bis 1200 C bei 12 mm Druck von javanischem
EMI1.2
lutem Methylalkohol. so scheiden sich die Terpene ab und Geraniol, Citronelol und Citronellal bleiben in Lösung. die nach der Trennung der beiden Schichten durch Verdünnen mit Wasser, Abheben und neuerliches Fraktionieren leicht rein gewonnen werden können.

Process for the production of terpene-free essential oils.
The natural essential oils are known to be mixtures of aldehydes, alcohols, ketones and esters with terpene hydrocarbons. The active ingredients are almost without exception the former and so-called terpene-free oils have been on the market for a long time, which are the most effective. Should contain ingredients in concentrated form. Little has been known so far about the methods used in the deterpenization of essential oils. The scant information available only shows that the repeated use of fractional vacuum distillation in connection with the utilization of the lower solubility of the terpenes in dilute alcohol is used for deterpenization. (See Böeker Journal for Practical Chemistry (2) 89, p. 199).
However, these methods all suffer from the inconvenience of necessity.
EMI1.1
is sufficiently complete.
It has now been found. that when using a methyl alcoholic chlorinated calcium solution, the separation of the terpenes from essential oils is much easier.
If you mix z. B. the fraction from boiling point 100 to 1200 C at 12 mm pressure of Javanese
EMI1.2
lutem methyl alcohol. so the terpenes separate and geraniol, citronelol and citronellal remain in solution. which can easily be obtained in pure form after the two layers have been separated by diluting with water, lifting off and fractionating again.
