Levulinic Acid Biorefineries: New Challenges for Efficient Utilization of Biomass

Abstract Levulinic acid is a sustainable platform molecule that can be upgraded to valuable chemicals and fuel additives. This article focuses on the catalytic upgrading of levulinic acid into various chemicals such as levulinate esters, δ‐aminolevulinic acid, succinic acid, diphenolic acid, γ‐valerolactone, and γ‐valerolactone derivatives such valeric esters, 5‐nonanone, α‐methylene‐γ valerolactone, and other various molecular‐weight alkanes (C 9 and C 18 –C 27 olefins).
