一、順酐的定義和危險(xiǎn)性

1、 Definition and danger of maleic anhydride

順酐,又稱1,4-環(huán)己二酮,是一種無(wú)色透明、帶有芳香氣味的結(jié)晶狀物質(zhì),是一種有機(jī)化合物。順酐易燃、易爆、有毒,是一種危險(xiǎn)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(zhì),與酸、堿、氧化劑皆有反應(yīng)。

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、順酐的儲(chǔ)存和使用

2、 Storage and Use Safety of Maleic Anhydride

1.儲(chǔ)存

1. Storage security

儲(chǔ)存順酐時(shí),應(yīng)防火、防潮、防曬、防高溫。順酐的儲(chǔ)存溫度應(yīng)在5℃以下,相對(duì)濕度應(yīng)小于85%。另外,在儲(chǔ)存時(shí)要防止與其它易燃、易爆、有毒物品混放,避免發(fā)生危險(xiǎn)反應(yīng)。

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.

2.使用

2. Use Safety

使用順酐時(shí),使用人員應(yīng)穿戴好相應(yīng)的防護(hù)裝備,操作過(guò)程中要注意防護(hù)眼睛、呼吸系統(tǒng)和皮膚。使用后應(yīng)立即清洗設(shè)備,防止順酐殘留導(dǎo)致后續(xù)操作的危險(xiǎn)。

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.
