Title (EN) SUCCINIC ACID FROM BIOMASS
(FR) ACIDE SUCCINIQUE PROVENANT DE BIOMASSE
Abstract: front page image
(EN)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.
(FR)L'invention porte sur un procédé qui permet d'obtenir de l'acide succinique ou de l'anhydride succinique à partir de biomasse, à bon rendement, dans des conditions douces et tout en évitant des procédés de fermentation. Le procédé comprend l'obtention d'acide lévulinique à partir de biomasse et la conversion de l'acide lévulinique en acide succinique. Selon l'invention, ce dernier procédé est effectué par le fait de soumettre de l'acide succinique à une température élevée en présence d'acide nitrique. De préférence du pentoxyde de vanadium est ajouté comme catalyseur.
