　　目前，工业上坡东顺酸酐的生产工艺可分为苯氧化法、正丁烷氧化法、C4烯烃法和苯甲酸酐副产法。包括苯氧化法使用为广泛,但由于苯资源有限、C4烯烃和正丁烷为原料生产顺丁烯二酸酐技术应运而生,特别是丰富的天然气和油田伴生气的有大量的正丁烷资源,所以近年来是丁烷氧化法生产顺丁烯二酸酐技术发展迅速,一直主导山东顺酐生产，其生产能力约占世界顺酐总产量的80%。

　　At present, the production process of industrial uphill maleic anhydride can be divided into benzene oxidation method, n-butane oxidation method, C4 olefin method and by-product method of benzoic anhydride. Including benzene oxidation is the most widely used method, but due to the limited resources of benzene, the production of maleic anhydride from C4 olefins and n-butane, especially in countries rich in natural gas and oil field associated gas, there are a large number of n-butane resources, so in recent years, the production of maleic anhydride by butane oxidation has developed rapidly. Shandong directly dominates the production of maleic anhydride, and its production capacity accounts for about 80% of the world's total production of maleic anhydride.
