Abstract:
A process for synthesizing at least one levulinate ester, said process comprising the reaction of furfuryl alcohol with at least one other alcohol in the presence of water and at least one catalyst, said furfuryl alcohol being present in a quantity of at least 5% by weight, based on the total weight of the alcohols, and said catalyst comprising at least one triflate ligand and at least one metal selected from bismuth, gallium, aluminum, tin and iron.
