Method & Evidence

AimCan urban waste be effectively upcycled into a robust heterogeneous acid catalyst for the efficient conversion of levulinic acid into high-value alkyl levulinates with minimal environmental impact?
MethodExperimental research and chemical synthesis
ProcedurePine needles (urban waste) were processed in a single step to create a solid acid catalyst (PiNe–SO3H). This catalyst was then used to convert levulinic acid into various alkyl levulinates under mild conditions. The catalyst's reusability, reaction pathway, and environmental impact (E-factor, Ecoscale) were assessed.
