Abstract

La présente invention concerne un procédé de synthèse de l’acide lévulinique par l’hydratation d’alcool furfurylique à une température comprise entre 25 et 140°C en présence d’un catalyseur homogène acide et d’un solvant à base d’éther et/ou d’acétal. L’utilisation d’un tel solvant permet d’obtenir un rendement équivalent voir meilleur à ceux obtenus avec des solvants connus, tout en présentant des propriétés de stabilité importantes.
