Definitions
- the invention relates to the field of obtaining essential oils. More specifically, the invention relates to the extraction and fractionation of essential oils of vegetable origin.
- the invention finds particular application in the fields cosmetics, pharmaceuticals and food.
- Essential oils are traditionally produced by steaming, hydrodistillation or any other method, variant of the previous ones.
- the essential oils of citrus constitute a exception, since they can also be produced by pressing bark fruits.
- FR-A-2 771 408 discloses a process for producing extracts or flower oils.
- FR-A-1,311 766 A discloses a method of manufacturing perfume concentrates.
- oils essential may be, for example, to increase the aromatic intensity of the oil essential.
- the essential oil is subjected to an operation of deterpenation of the separation of terpene hydrocarbons and compounds functionalized whose aromatic notes are more interesting. It can also to eliminate various harmful or toxic constituents.
- Thujone for example, is a neurotoxic substance present in various essential oils used in food or aromatherapy purposes for example.
- Psoralens are photosensitizing compounds found in the essential oils of most citrus fruits and more particularly in the essential oil of bergamot. These Compounds must be absolutely eliminated before incorporation of the essential oil in cosmetic compositions.
- Organic solvents are further affected by various regulations. As an example, the existence of positive lists of solvents concerning food applications. We will also note the regulations relating to the emission of volatile organic compounds (VOCs), which may induce, in brief expiry, important constraints for manufacturers.
- VOCs volatile organic compounds
- Supercritical CO 2 treatment has the dual advantage of being a fractionation method without organic solvent and subjecting the feedstock to temperatures lower than those imposed by distillation. On the other hand, it requires specific equipment representing heavy investments.
- the main objective of the present invention is to propose a method of fractionation of essential oils not presenting the disadvantages of the processes of the state of the art.
- the invention relates to a method of fractionation of essential oils or fractions of essential oils characterized in that it comprises a step of contacting said oils with an extractant containing at least one fluorinated solvent so as to obtain a fluorinated phase and a non-fluorinated phase and a step of separation of fractions of essential oils contained in said fluorinated phase and in said non-fluorinated phase.
- the process described makes it possible to satisfy the requirements techniques of various treatments applied to essential oils or fractions of essential oils, both at laboratory and production scale industrial.
- the applications of the proposed method we find in particular the deterpenation of essential oils or the removal of certain harmful or toxic.
- the perfluorinated solvents more particularly concerned by the present invention are perfluoro N-methylmorpholine (also known commercially under the name PF5052), n-perfluoropentane (PF5050), n-perfluorohexane (PF5060), n-perfluoroheptane (PF5070) and n-perfluorooctane (PF5080) and their isomers.
- PF5052 perfluoro N-methylmorpholine
- PF505050 n-perfluoropentane
- PF5060 n-perfluorohexane
- PF5070 n-perfluoroheptane
- PF5080 n-perfluorooctane
- hydrofluoroethers more particularly concerned by the present invention are methoxynonafluorobutane (C 4 F 9 -O-CH 3 ), also called HFE7100, and ethoxynonafluorobutane (C 4 F 9 -OC 2 H 5 ), also called HFE7200, and their isomers.
- the phase containing the fluorinated solvent is enriched mainly in monoterpene hydrocarbons and, to a lesser extent, in sesquiterpene hydrocarbons.
- the non solubilized by fluorinated solvents is mainly enriched in functionalized constituents with protic functions (alcohols, phenols) and in a measurement of functionalized compounds with non-protic functions (esters, ethers, aldehydes, ketones ).
- the constituents of the fluorinated phase can be recovered by evaporation of the extractant, preferably under reduced pressure in order to reduce the temperature of the treatment.
- the non-fluorinated phase which contains only a small amount of extractant, can be treated the same way.
- the non-fluorinated phase may, where appropriate, be cooled to cause demixing or precipitation of the constituents less soluble. These can then be easily recovered and desolventized.
- the fluorinated phase may also be treated by cooling as indicated above.
- fractionation can be carried out in batch mode, in semi-continuous mode or in continuous mode. If the solubility of hydrocarbons in a given fluorinated solvent is considered too low, the semi-continuous mode will be preferred. He will have the advantage, for example, of meeting productivity requirements when implementation of the process in an industrial setting.
- the essential oil is kept in an enclosure whose temperature is set at a considered value as optimal for extraction.
- the fluorinated solvent distributed in the form of droplets, passes through the layer of essential oil from below upward under the effect of difference in density of the two liquid phases.
- the fluorinated phase loaded with extract, is collected at the bottom of the extraction stage and then directed to a floor of separation of the extractant and the extracted constituents by distillation. The extractant thus regenerated is recycled to the extraction stage.
- the temperature of the extractant from the recycling stage can then be brought to this same value, by passing the extractant in an exchanger before distribution in the charge to be treated.
- This example is intended to quantify the partition coefficient of the main tracers of clove essential oil between a fluorinated solvent and the oil essential itself.
- the fluorinated solvents tested are perfluorohexane (PF5060), perfluorooctane (PF5080) and perfluoro N-methylmorpholine (PF5052).
- oil essential clove was chosen because of its high eugenol content, compound comprising a free phenolic hydroxyl and a phenolic hydroxyl engaged in an ether link.
- the fractionation of 100 g of essential oil is carried out with 100 g of fluorinated solvent.
- the mixture is stirred for 20 minutes at 25 ° C. After settling, the two liquid phases are volumized and analyzed by chromatography in phase gas.
- Table 2 specifies, for each fluorinated solvent tested, the partition coefficient (K eq ), between the two phases at equilibrium, of the main tracers of the essential oil; K is defined as the ratio of the concentrations of each tracer in the fluorinated phase and in the supernatant essential oil when the biphasic system is at equilibrium.
- the table further specifies, for each tracer, its initial content in the essential oil (C i ) and its chemical family of membership or functionalization.
- the fractionation of 100 g of essential oil is carried out with 100 g of fluorinated solvent.
- the mixture is stirred for 20 minutes at 25 ° C. After settling, the two liquid phases are volumized and analyzed by chromatography in phase gas.

- the table further specifies, for each tracer, its initial content in the essential oil (C i ) and its chemical family of membership or functionalization.
- the extraction is carried out in a liquid / liquid extractor operating in semi-continuously.
- the extraction stage containing the essential oil is equipped with a jacket powered by a thermostatic fluid.
- the extraction stage is fed PF5060 (perfluorohexane) from the recycling stage and distributed in the form of droplets in the layer of essential oil.

- the fluorinated phase, charged in extract is sent back to the boiler of the recycling stage by a system overflow.
- the flow rate of recycled fluorinated solvent is set by adjusting the power of boiler heating.
- Table 7 indicates the mass content of the main tracers of the original essential oil of oregano, the raffinate at the end of treatment and the extract obtained.
- main tracers chemical family % in the initial oil % in raffinate % in the excerpt ⁇ -thujene monoterpène 1.1 0.3 4.2 ⁇ -terpinene 1.0 0.3 3.4 ⁇ -myrcene 2.3 0.7 7.8 ⁇ -terpinene 4.1 1.0 14.8 p -cymene 13.0 4.0 42.8 ⁇ -caryophyllene sesquiterpène 3.1 0.7 11.0 linalool monoterpene alcohol 2.1 2.6 0.4 carvacrol single OH phenol free and sterically hindered 67.1 86.0 5.3
- the raffinate obtained is thus enriched to 86% in carvacrol against 67% in the oil starting point by extraction of 80% terpene hydrocarbons.

- ils sont ininflammables et n'imposent pas, de ce fait, l'utilisation d'équipements particuliers de production et de protection. Cette caractéristique est particulièrement intéressante dans des perspectives de production à l'échelle industrielle puisqu'elle a une incidence directe sur le coût des produits finis ;
