一、顺酐的定义和危险性

1、 Definition and danger of maleic anhydride

顺酐，又称1,4-环己二酮，是一种无色透明、带有芳香气味的结晶状物质，是一种有机化合物。顺酐易燃、易爆、有毒，是一种危险品类。

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.

顺酐易燃，可以在空气中自燃，接触火源易爆炸。顺酐在水中不溶，但可以溶于醇类和酮类物质，与酸、碱、氧化剂皆有反应。

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.

二、顺酐的储存和使用

2、 Storage and Use Safety of Maleic Anhydride

储存

Storage security

储存顺酐时，应防火、防潮、防晒、防高温。顺酐的储存温度应在5℃以下，相对湿度应小于85%。另外，在储存时要防止与其它易燃、易爆、有毒物品混放，避免发生危险反应。

When storing maleic anhydride, it should be fireproof, moisture-proof, sun proof, and heat-resistant. The storage temperature of maleic anhydride should be below 5 ℃ and the relative humidity should be less than 85%. In addition, during storage, it is necessary to prevent mixing with other flammable, explosive, and toxic substances to avoid dangerous reactions.

使用

Use Safety

使用顺酐时，使用人员应穿戴好相应的防护装备，操作过程中要注意防护眼睛、呼吸系统和皮肤。使用后应立即清洗设备，防止顺酐残留导致后续操作的危险。

When using maleic anhydride, the user should wear corresponding safety protective equipment, and pay attention to protecting the eyes, respiratory system, and skin during operation. After use, the equipment should be cleaned immediately to prevent the danger of residual maleic anhydride in subsequent operations.
