順酐是一種有機化學品，又稱順丁烯二酸酐，馬來酸酐，2,5-呋喃二酮等。斜方晶系無色針狀或片狀晶體。有強烈刺激氣味，溶于乙醇、乙醚和丙酮，難溶于石油醚和四氯化碳。與熱水作用而成馬來酸。
順酐廠家認為其出售過程一般包括以下幾個步驟：
Maleic anhydride is an organic chemical, also known as maleic anhydride, maleic anhydride, 2,5-furanedione, and so on. Orthorhombic crystals are colorless needle shaped or sheet shaped crystals. It has a strong pungent odor and is soluble in ethanol, ether, and acetone, but is difficult to dissolve in petroleum ether and carbon tetrachloride. It reacts with hot water to form maleic acid. Maleic anhydride manufacturers believe that the production and sales process generally includes the following steps:
原材料采購：順酐的主要原材料是氫氧化鈉和環氧丙烷，這些原材料需要從供應商處采購。
Raw material procurement: The main raw materials for maleic anhydride are sodium hydroxide and propylene oxide, which need to be purchased from suppliers.
過程：順酐的過程包括酯化反應、脫水反應和氫化反應等步驟，需要在化工廠進行。
Production process: The production process of maleic anhydride includes steps such as esterification reaction, dehydration reaction, and hydrogenation reaction, which need to be carried out in a chemical plant.
質量檢測：出的順酐需要進行質量檢測，以確保其符合相關標準和要求。
Quality testing: The produced maleic anhydride needs to undergo quality testing to ensure that it meets relevant standards and requirements.
包裝和儲存：出的順酐需要進行包裝和儲存，以確保其在運輸和儲存過程中不受到污染和損害。
Packaging and storage: The produced maleic anhydride needs to be packaged and stored to ensure that it is not contaminated and damaged during transportation and storage.
銷售和配送：出的順酐可以通過銷售渠道進行銷售和配送，包括直接銷售給客戶、銷售給經銷商等。
Sales and distribution: The produced maleic anhydride can be sold and distributed through sales channels, including direct sales to customers and distributors.
售后服務：在順酐出售過程中，需要提供良好的售后服務，包括技術支持、產品回收和處理等。
After-sales service: In the process of selling maleic anhydride, it is necessary to provide good after-sales services, including technical support, product recovery, and treatment.
During the production and sale of maleic anhydride, production and quality testing need to be carried out in strict accordance with relevant standards and requirements to ensure product quality and safety, and good after-sales service needs to be provided to meet customer needs and requirements.
