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(gòu):順酐的主要原材料是氫氧化鈉和環(huán)氧丙烷,這些原材料需要從供應(yīng)商處采購(gòu)。
Raw material procurement: The main raw materials for maleic anhydride are sodium hydroxide and propylene oxide, which need to be purchased from suppliers.
過(guò)程:順酐的過(guò)程包括酯化反應(yīng)、脫水反應(yīng)和氫化反應(yīng)等步驟,需要在化工廠進(jìn)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(zhì)量檢測(cè):出的順酐需要進(jìn)行質(zhì)量檢測(cè),以確保其符合相關(guān)標(biāo)準(zhǔn)和要求。
