Fatty acid esters are manufactured in a reaction between a fatty acid source and at least one reagent. The source and the reagent are of limited mutual solubility. The reaction is conducted in a reactor involving at least two tubes. At least one of the tubes spins relatively to the other. The reaction may include spinning at least one of the tubes for a reaction time to generate a product medium, removing product medium from the reactor, and separating the removed product medium into at least one lipophilic phase and at least one hydrophilic phase. Selon l'invention, les esters d'acides gras sont fabriqués au cours de la réaction entre une source d'acides gras et au moins un réactif. La source et le réactif sont de solubilité mutuelle limitée. La réaction est conduite dans un réacteur faisant intervenir au moins deux tubes. Au moins l'un des tubes tourne par rapport à l'autre. La réaction peut comprendre la rotation d'au moins l'un des tubes pendant un temps de réaction pour générer un milieu de produit, l'élimination du milieu de produit du réacteur et la séparation du milieu de produit éliminé en au moins une phase lipophile et au moins une phase hydrophile.
