　　目前，工業上坡東順酸酐的生產工藝可分為苯氧化法、正丁烷氧化法、C4烯烴法和苯甲酸酐副產法。包括苯氧化法使用為廣泛,但由于苯資源有限、C4烯烴和正丁烷為原料生產順丁烯二酸酐技術應運而生,特別是豐富的天然氣和油田伴生氣的有大量的正丁烷資源,所以近年來是丁烷氧化法生產順丁烯二酸酐技術發展迅速,一直主導山東順酐生產，其生產能力約占世界順酐總產量的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.
