Maleic anhydride is usually referred to as maleic anhydride, and it is a highly reactive organic compound with pungent odor. Secondly, because of its good properties, it has become a chemical intermediate in Industrial Chemistry and is widely used in various fields.

一般工廠會通過各種方式開展順酐的制作，其中較為常見制作方法為苯氧化法。通常材料會在催化劑的作用下，在固定床中發(fā)生氧化反應，同時生成順丁烯二酸酐。隨后會用水吸收并且生成順丁烯二酸。其次，會在經(jīng)共沸脫水和精餾、刮片得到成品。

  Usually, the materials will be oxidized in a fixed bed under the action of catalyst, and maleic anhydride will be produced at the same time. It is then absorbed with water and maleic acid is formed. Secondly, after azeotropic dehydration, rectification and scraping, the finished product is obtained.

同時由于其擁有較好的特性，所以使得該材料被廣泛的運用在每個工業(yè)化學中。并且該材料還可以進行石油添加劑、紙張施膠、環(huán)氧固化劑和水處理化學品等產(chǎn)品的制作。

   at the same time, because of its good properties, it is widely used in every industrial chemistry. And the material can also be used for the production of petroleum additives, paper sizing, epoxy curing agent and water treatment chemicals.
