一、順酐的定義和危險性

順酐，又稱1,4-環己二酮，是一種無色透明、帶有芳香氣味的結晶狀物質，是一種有機化合物。順酐易燃、易爆、有毒，是一種危險品類。

Maleic anhydride, also known as 1,4-cyclohexanedione, is a colorless, transparent, aromatic crystalline substance and an organic compound. Maleic anhydride is flammable, explosive, and toxic, and is a hazardous class.

順酐易燃，可以在空氣中自燃，接觸火源易爆炸。順酐在水中不溶，但可以溶于醇類和酮類物質，與酸、堿、氧化劑皆有反應。

Maleic anhydride is flammable and can self ignite in the air. It is prone to explosion when in contact with a fire source. Maleic anhydride is insoluble in water, but can dissolve in alcohols and ketones, and reacts with acids, bases, and oxidants.
