Abstract Disclosed is a method that allows obtaining succinic acid or succinic anhydride from biomass, with good yield, under mild conditions and yet avoiding fermentative processes. The method comprises obtaining levulinic acid from biomass, and converting the levulinic acid into succinic acid. According to the invention, the latter process is conducted by subjecting succinic acid to elevated temperature in the presence of nitric acid. Preferably vanadium pentoxide is added as a catalyst.
