顺酐由苯经催化氧化或由丁烯或丁烷用空气氧化而制得，溶于乙醇、乙醚和丙酮，难溶于石油醚和四氯化碳，与热水作用而成马来酸;

Maleic anhydride is produced by catalytic oxidation of benzene or oxidation of butene or butane with air. It is soluble in ethanol, ether, and acetone, but insoluble in petroleum ether and carbon tetrachloride. It reacts with hot water to form maleic acid;

顺酐的外观是白色片状结晶，有粉末状、针状、片状、丸状、棒状、团块状或熔融物质，相对密度是1.480，熔点在52.8°℃，沸点是202.2℃，闪点:110.0°℃。

The appearance of maleic anhydride is a white crystalline flake, with powder, needle, flake, pellet, rod, clump or molten substances. The relative density is 1.480, the melting point is 52.8 ° C, the boiling point is 202.2 ° C, and the flash point is 110.0 ° C.

顺酐的作用:用于双烯合成、制药物、农药、染料中间体及制聚酯树脂、醇酸树脂、马来酸等有机酸，也用作脂肪和油防腐剂等，生产不饱和聚酯树脂、醇酸树脂、、长效碘胺的原料。也是涂料、马来松香、聚马来酐、顺酐-苯乙烯共聚物的共聚单体，也是生产油墨助剂、造纸助剂、增塑剂、酒石酸、富马酸、四氢呋喃等的有机化工原料。

The function of maleic anhydride: used in the synthesis of dienes, pharmaceuticals, pesticides, dye intermediates, as well as in the production of organic acids such as polyester resin, alkyd resin, maleic acid, etc. It is also used as a preservative for fats and oils, and as a raw material for the production of unsaturated polyester resin, alkyd resin, and long-acting iodoamine. It is also a comonomer of coatings, maleic rosin, polymaleic anhydride, and maleic anhydride styrene copolymers. It is also an organic chemical raw material for the production of ink additives, papermaking additives, plasticizers, tartaric acid, fumaric acid, tetrahydrofuran, and other chemicals.
