• Maleic anhydride is produced by vapor-phase oxidation of n-butane.
• The overall process converts the methyl groups to carboxylate and dehydrogenates the backbone.
• The selectivity of the process reflects the robustness of maleic anhydride, with its conjugated double-bond system.
• and the mixture is passed through a catalyst bed at high temperature.
