In the chemical industry, the relevant factories will choose maleic anhydride as raw material for the production of high demand polymers or compounds. At the same time, in the daily production, the operator will add an appropriate amount of additives to maleic anhydride, so as to increase the hardness and service life of maleic anhydride.

一般工厂所使用的顺酐是一种无色或白色的固体，同时具有菱形晶体结构且带有刺鼻的气味。在日常的过程中，相关的制造厂会将苯和丁烷送入热气流中，并且混合物会在高温下通过催化剂。然后，操作员会控制空气与碳氢化合物的比例，从而保证材料的纯度。

   maleic anhydride used in general factories is a colorless or white solid with rhombic crystal structure and pungent odor. In the daily production process, the relevant manufacturers will send benzene and butane into the hot gas stream, and the mixture will pass through the catalyst at high temperature. The operator then controls the ratio of air to hydrocarbon to ensure the purity of the material.

随着技术的不断进步，促使日常加工中所使用的技术也得到了相应的提升。并且由于技术的提升，使得材料的质量也得到了相应的提升。因此，被广泛的运用在水溶性聚合物、人造甜味剂等产品中。

With the continuous progress of technology, the technology used in daily processing has also been improved accordingly. And due to the improvement of technology, the quality of materials has been improved accordingly. Therefore, it is widely used in water-soluble polymers, artificial sweeteners and other products.
