Perhaps a small number of people will call maleic anhydride maleic anhydride. At the same time, it is colorless or white solid in pure state and has an unpleasant smell. Moreover, it has two types of chemical energy groups, which makes it very useful in chemical synthesis and other applications.

以前，工厂会通过苯或其它芳族化合物的氧化制得的。但随着部分材料的上涨，使得工厂会使用正丁烷作为原料。苯和丁烷会被送入热气流中，并且会在高温下通过催化剂床。随后，工人会控制空气与碳氢化合物，从而减少混合物发生着火的可能。其次，产品会通过排料口排出。

In the past, it was prepared by the factory through the oxidation of benzene or other aromatic compounds. However, with the price rise of some materials, the factory will use n-butane as raw material. Benzene and butane are fed into the hot gas stream and pass through the catalyst bed at high temperature. Workers then control the air and hydrocarbons to reduce the possibility of ignition of the mixture. Secondly, the product will be discharged through the discharge port.

同时由于其具有两种类型的化学能团，所以被广泛运用在化学合成和其它应用中。除此之外，她还被广泛运用在合成表面活性剂、杀虫剂、除草剂和杀真菌剂等应用中。

At the same time, because it has two types of chemical energy groups, it is widely used in chemical synthesis and other applications. In addition, it is also widely used in synthetic surfactants, pesticides, herbicides and fungicides.
