OXIDATION OF BENZENE
Benzene oxidation is the oldest method to produce maleic anhydride. The reaction occurs at approximately 380°C and atmospheric pressure. A mixture of V2O5/MO3 is the usual catalyst. Benzene conversion reaches 90%, but selectivity to maleic anhydride is only 50–60%; the other 40–50% is completely oxidized to CO2:
Currently, the major route to maleic anhydride, especially for the newlyerected processes, is the oxidation of butane. Maleic anhydride
also comes from oxidation of n-butenes.
