2. 用于制造染料和颜料

2. Used for manufacturing dyes and pigments

顺酐可以直接与酰胺、芳香胺等化合物反应,得到多种新型染料和颜料,广泛应用于纺织、印刷、油漆等领域。其中一些染料和颜料具有高色牢度、彩度饱和度好、不易褪色等特点。

Maleic anhydride can directly react with compounds such as amides and aromatic amines to obtain various new dyes and pigments, which are widely used in fields such as textiles, printing, and paint. Some of these dyes and pigments have high color fastness, good color saturation, and are not easily faded.

3. 用于制造医药中间体

3. Used for manufacturing pharmaceutical intermediates

顺酐的一个重要衍生物是马来酸脂,它既可用作润滑剂,也可用作抗真菌药物、止痛药、安眠药等医药中间体,具有广泛应用前景。

An important derivative of maleic anhydride is maleic acid ester, which can be used as a lubricant, as well as a pharmaceutical intermediate such as antifungal drugs, analgesics, and sleeping pills, and has broad application prospects.

4. 用于制造植物生长调节剂

4. Used for manufacturing plant growth regulators

通过顺酐和乙醇反应,可制得一种生物活性物质——丙烯酸盐。它是一种植物生长调节剂,可以促进作物生长、提高产量和品质。

A bioactive substance, acrylic acid salt, can be produced by reacting maleic anhydride with ethanol. It is a plant growth regulator that can promote crop growth, increase yield and quality.

5. 用于环境领域

5. Used in the field of environmental protection

顺酐可以用于处理废水、废气、废渣等环境污染物。例如,顺酐和氨之间反应可以生成顺酐酰胺,用于处理废水中的氮化合物;顺酐和苯乙烯之间反应可以制得苯乙烯马来酸脂共聚物,用于处理废气中的VOCs

Maleic anhydride can be used to treat environmental pollutants such as wastewater, exhaust gas, and waste residue. For example, the reaction between maleic anhydride and ammonia can generate maleic anhydride amide, which is used to treat nitrogen compounds in wastewater; The reaction between maleic anhydride and styrene can produce styrene maleic acid copolymer, which is used to treat VOCs in waste gas

总的来说,顺酐在有机化工、建筑、航空、汽车、电子、纺织、印刷、油漆、医药、农业等领域都有广泛应用。未来随着科技的不断发展,顺酐的用途和应用领域还将不断拓展。

Overall, maleic anhydride has a wide range of applications in organic chemical, construction, aviation, automotive, electronics, textiles, printing, painting, medicine, agriculture, and other fields. With the continuous development of technology in the future, the use and application fields of maleic anhydride will continue to expand.
