摘　　要：顺酐生产工艺分为苯氧化法、正丁烷氧化法、C_(4)烯烃法和苯酐副产法,我国顺酐生产工艺主要采用苯氧化法和正丁烷氧化法。当前我国顺酐行业处于供过于求状态,部分产能需要依靠出口消化。文章简述了顺酐的各种生产工艺并对其进行了对比,分析了我国顺酐的产能并对行业的发展提出了建议。The production process of maleic anhydride can be categorized into four methods:benzene oxidation,n-butane oxidation,C 4 olefins oxidation,and phthalic anhydride by-product.In China,the predominant processes for maleic anhydride production are the benzene oxidation and n-butane oxidation methods.Currently,China’s maleic anhydride industry faces a situation of overcapacity,necessitating the export of surplus production to balance supply and demand.This paper provides a detailed description and comparison of the production processes of maleic anhydride,analyzes the current production capacity in China,and offers recommendations for the future development of the maleic anhydride industry.
