Abstract

The present invention relates to a process for synthesizing levulinic acid by hydrating furfuryl alcohol at a temperature between 25 and 140°C in the presence of a homogeneous acidic catalyst and an ether- and / or acetal-based solvent. The use of such a solvent makes it possible to obtain a yield equivalent to, or even better than, those obtained with known solvents, while exhibiting significant stability properties.
