順丁烯二酸酐又名馬來酸酐或失水蘋果酸酐,常簡稱順酐。無色結(jié)晶,有強烈刺激氣味。常溫下白色顆粒狀、針狀、片狀、棒狀、塊狀或塊團狀,具有強刺激性。
Maleic anhydride, also known as maleic anhydride or dehydrated malic anhydride, is often referred to as maleic anhydride. Colorless crystal with strong pungent smell. At room temperature, it is white, granular, needle like, sheet-shaped, rod-shaped, blocky or lump like, with strong irritation.
相對密度1.48,熔點52.8℃,沸點202.2℃,在較低溫度下(60-80℃)也能升華,能溶于醇、乙醚和丙酮,與水作用生成順丁烯二酸??扇肌⑵湔羝头蹓m與空氣混合,可形成爆炸混合物。
The relative density is 1.48, the melting point is 52.8 ℃, and the boiling point is 202.2 ℃. It can also be sublimated at a lower temperature (60-80 ℃). It can dissolve in alcohol, ether and acetone, and react with water to form maleic acid. Combustible, its steam and dust mixed with air, can form explosive mixture.
主要由苯或碳四餾分中的正丁烷或丁烯氧化而制得,是不飽和聚酯及有機合成的原料。
It is mainly prepared by oxidation of n-butane or butene in benzene or C4 fraction. It is a raw material for the production of unsaturated polyester and organic synthesis.

Manufacture polyester resin, alkyd resin, pesticide, fumaric acid, paper treatment agent and so on. Maleic anhydride is an important organic chemical intermediate, which can be used to make plasticizer in plastic industry, paper treatment agent in paper industry, unsaturated polyester resin in synthetic resin industry, alkyd coating in coating industry, malathion synthesis in pesticide production, sulfonamide drug production in pharmaceutical industry, etc.
近年來以其為主要原材料的丁二酸、酒石酸產(chǎn)業(yè)迅速擴大,其在工程建筑、食品調(diào)味劑、生物拆分劑等領(lǐng)域的應(yīng)用得以不斷擴大。以順酐為原料的下游衍生物如1,4-丁二醇、四氫呋喃、γ丁內(nèi)脂等亦有很大的發(fā)展
In recent years, the industry of succinic acid and tartaric acid, whose main raw materials are succinic acid and tartaric acid, has been expanded rapidly, and its application in engineering construction, food flavoring agent, biological resolution agent and other fields has been continuously expanded. The downstream derivatives of maleic anhydride such as 1,4-butanediol, tetrahydrofuran, γ - butyrolactone, etc
