A PROCESS FOR THE PREPARATION OF GAMMA-VALEROLACTONE BY CATALYTIC HYDROGENATION OF LEVULINIC ACID USING RU-BASED CATALYSTS

摘要

The present invention discloses a fast and selective process for the preparation of γ- valerolactone (Gvl) by catalytic hydrogenation of biomass-derived levulinic acid (LA) using recyclable ruthenium (Ru)-based heterogeneous catalysts in aqueous medium in stoichiometric yields (~100%) under mild reaction conditions using nearly required amount of hydrogen.
