Polyimide resins, epoxy resins, unsaturated polyester resins, etc. synthesized from maleic anhydride have been widely used in manufacturing fields such as construction, aviation, automotive, and electronics. Their main characteristics are heat resistance, corrosion resistance, insulation, wear resistance, and high strength.

2. 用于制造染料和顏料

2. Used for manufacturing dyes and pigments

順酐可以直接與酰胺、芳香胺等化合物反應(yīng)，得到多種新型染料和顏料，廣泛應(yīng)用于紡織、印刷、油漆等領(lǐng)域。其中一些染料和顏料具有高色牢度、彩度飽和度好、不易褪色等特點(diǎn)。

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. 用于制造醫(yī)藥中間體

3. Used for manufacturing pharmaceutical intermediates

順酐的一個(gè)重要衍生物是馬來酸脂，它既可用作潤(rùn)滑劑，也可用作抗真菌藥物、止痛藥、安眠藥等醫(yī)藥中間體，具有廣泛應(yīng)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. 用于制造植物生長(zhǎng)調(diào)節(jié)劑

4. Used for manufacturing plant growth regulators

通過順酐和乙醇反應(yīng)，可制得一種生物活性物質(zhì)——丙烯酸鹽。它是一種植物生長(zhǎng)調(diào)節(jié)劑，可以促進(jìn)作物生長(zhǎng)、提高產(chǎn)量和品質(zhì)。

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. 用于環(huán)境領(lǐng)域

5. Used in the field of environmental protection

順酐可以用于處理廢水、廢氣、廢渣等環(huán)境污染物。例如，順酐和氨之間反應(yīng)可以生成順酐酰胺，用于處理廢水中的氮化合物；順酐和苯乙烯之間反應(yīng)可以制得苯乙烯馬來酸脂共聚物，用于處理廢氣中的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

總的來說，順酐在有機(jī)化工、建筑、航空、汽車、電子、紡織、印刷、油漆、醫(yī)藥、農(nóng)業(yè)等領(lǐng)域都有廣泛應(yīng)用。未來隨著科技的不斷發(fā)展，順酐的用途和應(yīng)用領(lǐng)域還將不斷拓展。
