摘要:
A method for extracting an unsaponifiable fraction from a solid renewable raw material, includes the solid-liquid extraction of the fats from the solid renewable raw material in the presence of at least one polar organic solvent and at least one non-polar cosolvent immiscible with the polar organic solvent, resulting in the formation of a polar organic phase enriched in lipids functionalized with one or more function(s) chosen from hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine functions, and of a non-polar organic phase enriched in lipids containing no or few hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine function(s), then the concentration of the organic phases.

A method for extracting an unsaponifiable fraction from a solid renewable raw material, includes the extraction of the fats from the solid renewable raw material, leading to the production of an oil, the concentration of the oil so as to obtain a mixture enriched in unsaponifiable fraction, and the liquid-liquid extraction of the mixture enriched in unsaponifiable fraction, in the presence of at least one polar organic solvent and at least one non-polar cosolvent immiscible with the polar organic solvent, resulting in the formation of an organic polar phase enriched in lipids functionalized with one or more function(s) chosen from hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine functions, and to the formation of a non-polar organic phase enriched in lipids containing no or few hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine function(s), then the concentration of the organic phases.
摘要:
A method for extracting an unsaponifiable fraction from a renewable raw material, includes the reactive trituration of the raw material dehydrated in the presence of at least one polar organic solvent including at least one light alcohol, at least one non-polar cosolvent immiscible with the light alcohol and at least one catalyst, resulting in the formation of a polar organic phase enriched with lipids functionalized with one or more function(s) chosen from hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine functions, and of a non-polar organic phase enriched with lipids containing no or few hydroxyl, epoxide, ketone, thiol, aldehyde, ether and amine function(s), and thereafter the concentration of the organic phases.
