<p>The present invention relates to a process for the selective extraction of monoglycerides present in a fraction of fatty acid alkyl esters (FAAEs), comprising at least one stage of liquid-liquid extraction by means of a polar solvent (PS) comprising a light alcohol and optionally of a nonpolar solvent (NS) comprising a solvent which is immiscible with the light alcohol. The present invention relates in particular to a fraction of fatty acid alkyl esters (FAAEs) of vegetable or animal origin, used in particular in biodiesels, capable of being obtained according to the process of the invention, so that its content of monoglycerides is less than 0.6%.</p> |
