How to make maleic anhydride from benzene?
- The production of maleic anhydride from benzene is a vapor-phase oxidation reaction with a fixed bed catalyst comprising vanadium and molybdenum mixed oxides. The best catalyst for the oxidation of benzene is a mixture of V 2 O 5 + MoO 3, which is usually supported on wide-porous Al 2 ? 3.
What is the history of maleic anhydride?
- Maleic anhydride was first commercially produced in the early 1930s by the vapor-phase oxidation of benzene. The use of benzene as a feedstock for the production of maleic anhydride was dominant in the world until the 1980s. Several processes to produce maleic anhydride from benzene were developed, the most common of them was Scientific Design.
What is the production of maleic anhydride from n-butane?
- The production of maleic anhydride from n-butane is a vapor-phase oxidation process based upon use of a heterogeneous catalyst containing vanadium and phosphorus mixed oxides. The n-butane oxidation reaction producing maleic anhydride is highly exothermic.
What is the selectivity of maleic anhydride?
- The selectivity for each reaction is as follows [2]: (1) maleic anhydride 70.0% (2) carbon dioxide 1.0% (3) acrylic acid 1.0% (4) formic acid 1.0% Data that may provide reaction kinetics can be found in US patent 4,317,778. The process was simulated using the Peng-Robinson thermodynamic package for K- values and Peng-Robinson for enthalpy.
