Abstract
A method for synthesizing a composition comprising at least one acid ester stemming from the biomass and an organic biosolvent is provided. The method comprises the esterification reaction between at least one acid stemming from the biomass and at least one alcohol, in the presence of an acid catalyst and of the organic biosolvent, the organic biosolvent being selective of the ester or of the esters formed relatively to the acid or to the starting acids and non-miscible with the alcoholic solution of the acid stemming from the biomass.
