"Manufacture Of Maleic Anhydride From Renewable Materials, Maleic Anhydride Obtained And Uses Thereof"

Abstract: The present application concerns a process for manufacturing maleic anhydride, comprising the following steps: a) fermenting renewable raw materials and optional purification in order to produce a mixture comprising at least butanol; b) oxidizing butanol to maleic anhydride at a temperature generally in the range 300°C to 600°C, using a catalyst based on oxides of vanadium and/or molybdenum; c) isolating the maleic anhydride obtained at the end of step b) . It also concerns maleic anhydride obtained from renewable raw materials, copolymers and compositions comprising said maleic anhydride, and also uses of said maleic anhydride.
