马来酸酐通过正丁烷的气相氧化产生，整个过程将甲基转化为羧酸盐并使骨架脱氢，该方法的选择性反映了马来酸酐及其共轭双键体系的稳健性。
Maleic anhydride is produced by the gas-phase oxidation of n-butane. In the whole process, methyl is converted to carboxylate and the skeleton is dehydrogenated. The selectivity of this method reflects the robustness of maleic anhydride and its conjugated double bond system.
传统上，顺酐厂家是通过苯或其他芳族化合物的氧化产生的，截2006年，只有少数小型工厂继续使用苯。
Traditionally, maleic anhydride is produced by oxidation of benzene or other aromatic compounds. As of 2006, only a few small factories continued to use benzene.

在两种情况下，将苯和丁烷加入热空气流中，使混合物在高温下通过催化剂床。控制空气与碳氢化合物的比例以防止混合物点燃。五氧化二钒和三氧化钼是用于苯途径的催化剂，而磷酸钒用于丁烷途径：C4H10 + 3.5O2→C4H2O3 +4H2OΔH= -1236kJ / mol
In both cases, benzene and butane are added to the hot air stream to make the mixture pass through the catalyst bed at high temperature. Control the air to hydrocarbon ratio to prevent ignition of the mixture. Vanadium pentoxide and molybdenum trioxide are catalysts for benzene pathway, while vanadium phosphate is used for butane pathway: C4H10 + 3.5o2 → c4h2o3 + 4H2O Δ H = - 1236kj / mol
主要的竞争过程需要丁烷的完全燃烧，这种转化的放热是部分氧化的两倍。
the main competitive process requires complete combustion of butane, and the exothermic rate of this conversion is twice that of partial oxidation.
