Description

Verfahren zur Trennung von Thymol und Carvacrol Die beiden Phenole der p-Cymolreihe, i-Methyl-3-oxy-4-isopropylbenzol (Thymol) und t-Methyl-2-oxy-4-isopropylbenzol (Carvacrol), zeigen chemisch so ähnliche Eigenschaften, daß eine Trennung dieser beiden Phenole aus ihren flüssigen Lösungsgegemischen Schwierigkeiten macht.Method of Separation of Thymol and Carvacrol The two phenols of the p-cymene series, i-methyl-3-oxy-4-isopropylbenzene (thymol) and t-methyl-2-oxy-4-isopropylbenzene (Carvacrol), show chemically similar properties that a separation of these makes both phenols difficult from their liquid solution mixtures.

Es wurde gefunden, daß die verschiedene Löslichkeit dieser Phenole in den Lösungen von Salzen arylierter Oxyfettsäuren zu einer Trennung beider Phenole benutzt werden kann. Beispiel. roo Gewichtsteile einer Mischung von gleichen Teilen Thymol und Carvacrol werden unter gelinder Erwärmung in 266o Gewichtsteilen einer r6,6prozentigen wäßrigen Lösung von carvacroxyessigsaurem Natrium gelöst. Beim Abkühlen dieser Lösung scheidet sich Thymol in reiner Form, in festem Zustand schön kristallisiert, aus und kann von der Lauge durch Filtrieren getrennt «-erden.It has been found that the different solubilities of these phenols in the solutions of salts of arylated oxy fatty acids to a separation of the two phenols can be used. Example. roo parts by weight of a mixture of equal parts Thymol and Carvacrol are gently heated in 266o parts by weight of a Dissolved r6.6% aqueous solution of sodium carvacroxyacetate. When cooling down this solution separates thymol in its pure form, nicely crystallized in a solid state, and can be separated from the lye by filtration.

Man kann bei dem vorstehend beschriebenen Verfahren andere Salze der Carvacroxvessigsäure wie auch Salze anderer geeigneter arylierter Oxy fettsäuren verwenden.You can use other salts of the method described above Carvacroxy acetic acid as well as salts of other suitable arylated oxy fatty acids use.
