Abstract

La présente invention concerne un procédé d'acylation de poly- ou d'oligosaccharides, par dilution d'un poly- ou oligosaccharide, dans au moins un liquide ionique et à l'étape A) par traitement avec au moins un acide en ajoutant éventuellement de l'eau, (étape A1), ou en ajoutant éventuellement de l'eau à température élevée (étape A2), et à l'étape B), le poly- ou oligosaccharide ainsi obtenu, dont le point de rosée est inférieur à celui du poly- ou oligosaccharide utilisé, est converti avec un agent acylant.
