順酐酸酐衍生物是以順酐為起始原料的酸酐，原料主要有順酐、丁二烯、混合碳四、混合碳五等基礎(chǔ)化工產(chǎn)品。順酐酸酐衍生物種類較多，包含甲基四氫苯酐、甲基六氫苯酐、四氫苯酐、六氫苯酐、甲基納迪克酸酐、甲基四氫苯酐等多種品種，主要用來(lái)合成聚酯樹(shù)脂、環(huán)氧樹(shù)脂固化等。
Maleic anhydride derivative is an anhydride produced from maleic anhydride. The raw materials mainly include maleic anhydride, butadiene, mixed C4, mixed C5 and other basic chemical products. There are many kinds of maleic anhydride derivatives, including methyl tetrahydrophthalic anhydride, methyl hexahydrophthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methyl nadic anhydride, methyl tetrahydrophthalic anhydride and so on. They are mainly used to synthesize polyester resin, epoxy resin curing, etc.
下游以電子封裝（半導(dǎo)體、LED）、電氣絕緣（變壓器、互感器）、涂料（PCB油墨、UV涂料）等領(lǐng)域?yàn)橹鳎粦?yīng)用在電子元器件、電氣設(shè)備、涂料等多種領(lǐng)域，市場(chǎng)需求較高。
The downstream is mainly in the fields of electronic packaging (semiconductors, LEDs), electrical insulation (transformers, transformers), coatings (PCB ink, UV coatings) and so on. It is applied in various fields such as electronic components, electrical equipment, coatings and so on, with high market demand.
更關(guān)鍵的是，今年高層提出內(nèi)循環(huán)這個(gè)新名詞，明確表示進(jìn)行內(nèi)循環(huán)和外循環(huán)的雙輪驅(qū)動(dòng)來(lái)穩(wěn)定國(guó)內(nèi)經(jīng)濟(jì)，并且目前逆全球化的事件也越來(lái)越多，未來(lái)實(shí)現(xiàn)完全的自主可控才是內(nèi)循環(huán)的關(guān)鍵所在。（政策支持、發(fā)展方向明確）
More importantly, this year, the high-level put forward the new term of internal circulation, which made it clear that the two wheel drive of internal circulation and external circulation will stabilize the domestic economy. At present, there are more and more anti globalization events, and the key to the internal circulation is to realize complete autonomy and control in the future（ National policy support and clear development direction)
我國(guó)順酐酸酐衍生物行業(yè)起步較晚，但隨著近幾年國(guó)內(nèi)化工產(chǎn)業(yè)的發(fā)展，逐漸打破了國(guó)外壟斷的局面，產(chǎn)品種類不斷增長(zhǎng)，當(dāng)前國(guó)內(nèi)工藝較為成熟的產(chǎn)品有四氫苯酐、甲基四氫苯酐等。
China's maleic anhydride derivative industry started late, but with the development of domestic chemical industry in recent years, it has gradually broken the situation of foreign monopoly, and the types of products are growing. At present, the products with mature domestic production technology include tetrahydrophthalic anhydride, methyl tetrahydrophthalic anhydride, etc.
