The main business methods of maleic anhydride manufacturers are benzene oxidation, butene oxidation and n-butane oxidation.

　　1. 苯氧化過程中苯在v-mo-p催化劑的作用下，在固定床上發生氧化反應，形成山東順丁烯二酸酐，反應溫度為365℃(反應床也可用于沸騰床，但消耗高)。再經吸水馬來酸，再經共沸脫水蒸餾，刮制成成品。

　　1. In the process of benzene oxidation, under the action of v-mo-p catalyst, benzene is oxidized in a fixed bed to form Shandong maleic anhydride. The reaction temperature is 365 ℃ (the reaction bed can also be used for boiling bed, but the consumption is high). Maleic acid is produced by water absorption, and then by azeotropic dehydration distillation, scraped into finished product.

　　2. 丁烷(或丁烯)氧化過程丁烷(或丁烯)在v-mo催化劑的作用下，由空氣或氧氧化山東順酐，反應溫度350-400℃。然后產品被吸收，脫水，然后用水提煉。

　　2. Butane (or butene) oxidation process butane (or butene) is oxidized by air or oxygen under the action of v-mo catalyst, and the reaction temperature is 350-400 ℃. The product is then absorbed, dehydrated, and refined with water.
