Maleic Anhydride From Normal &s or Benzene
Published: January 1976
Kuraray has developed a tungsten-phosphorus catalyst that converts n-butenes and butadiene to maleic anhydride. This review examines the competitive position of this catalyst when a mixture of butenes, butane, and butadiene is converted to maleic anhydride.
The results indicate that for new plants the Kuraray catalyst can be competitive with the Chevron and ChemSystems catalyst that are used for converting butane to MA. The manufacture of maleic anhydride from benzene rather than from saturated or unsaturated normal C4 proved to be an economic disadvantage.
