顺酐（马来酸酐）的爆炸极限为1.4-7.1%。

　　The explosive limit of maleic anhydride is 1.4-7.1%.

　　顺酐，又称马来酸酐，化学式为C4H2O3，在室温下为有强烈刺激性气味的白色晶体，熔点为51-56℃，沸点为202℃。顺酐易溶于水、丙酮、苯、氯仿等多数有机溶剂，且与水、强氧化剂、碱金属、强碱、胺、常见的金属、聚合催化剂和促进剂等不相容。

　　Maleic anhydride, also known as maleic anhydride, has the chemical formula C4H2O3. It is a white crystal with a strong pungent odor at room temperature, with a melting point of 51-56 ℃ and a boiling point of 202 ℃. Maleic anhydride is easily soluble in most organic solvents such as water, acetone, benzene, chloroform, and is incompatible with water, strong oxidants, alkali metals, strong bases, amines, the most common metals, polymerization catalysts, and promoters.

　　在储存时，顺酐应密封保存，并避免高于30℃的环境。此外，顺酐具有易燃性，因此在处理时应特别注意措施

　　When storing, maleic anhydride should be sealed and kept away from environments above 30 ℃. In addition, maleic anhydride is flammable, so special attention should be paid to safety measures when handling it
