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

　　1. 苯氧化过程中苯在v-mo-p催化剂的作用下，在固定床上发生氧化反应，形成山东顺丁烯二酸酐，反应温度为365℃(反应床也可用于沸腾床，但消耗高)。再经吸水生产马来酸，再经共沸脱水蒸馏，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)氧化过程丁烷(或丁烯)在v-mo催化剂的作用下，由空气或氧氧化山东顺酐，反应温度350-400℃。然后产品被吸收，脱水，然后用水提炼。

　　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.

　　主要产品有:顺丁烯二酸酐、邻苯二甲酸酐、双环戊二烯,纯对苯二甲酸,反丁烯二酸、滑石粉、乙二醇、二甘醇,苯乙烯,甘油,丙二醇,树脂醇、苯甲酸、三羟甲基丙烷,新戊二醇、丙烯酸和丙烯酸正丁酯、丙烯酸异辛酯、丙烯酸甲酯、丙烯酸乙酯、甲基丙烯酸酯、甲基丙烯酸甲酯、丙烯酸羟乙酯、丙烯酸羟丙酯和其他不饱和树脂,涂料,醇酸树脂,增塑剂，所需原料。
