精萘的主要應(yīng)用領(lǐng)域是染料及有機(jī)顏料中間體，產(chǎn)量大的是2-萘酚和H酸。我國(guó)已成為世界上大的染料和有機(jī)顏料生產(chǎn)國(guó)，近年來(lái)生產(chǎn)技術(shù)和產(chǎn)品結(jié)構(gòu)變化較大，但對(duì)精萘的需求總體呈平穩(wěn)增長(zhǎng)趨勢(shì)。

The main application fields of refined naphthalene are dyes and organic pigment intermediates, with a large output of 2-naphthol and H acid. China has become the world's largest producer of dyes and organic pigments. In recent years, the production technology and product structure have changed greatly, but the demand for refined
naphthalene has generally shown a steady growth trend.

萘在農(nóng)用化學(xué)品和醫(yī)藥領(lǐng)域也有重要應(yīng)用，這也是萘消費(fèi)中增長(zhǎng)快的部分。主要產(chǎn)品包括植物生長(zhǎng)調(diào)節(jié)劑和除草劑、熏蒸劑、鞣革劑、飼料添加劑、計(jì)生藥品等。此外，以萘為原料還可生產(chǎn)一種重要的功能高分子材料聚萘二甲酸乙二醇酯(PEN)，該產(chǎn)品早期市場(chǎng)主要是薄膜，潛在的市場(chǎng)用途包括柔性印刷線路板、電容器膜、薄膜開關(guān)、自動(dòng)記錄技術(shù)和可微波烘烤包裝材料等。另一種重要用途就是包裝容器，此外它還是一種工業(yè)用纖維原料，有望成為優(yōu)良的橡膠增強(qiáng)材料、工業(yè)電纜料以及造紙機(jī)套和過(guò)濾器用介質(zhì)單絲等。

Naphthalene also has important applications in agricultural chemicals and medicine, which is also the fastest growing part of naphthalene consumption. The main products include plant growth regulators and herbicides, fumigants, tanning agents, feed additives, family planning drugs, etc. In addition, naphthalene can also be used as raw material to produce an important functional polymer material, polyethylene naphthalate (PEN). The early market of this product is mainly film, and its potential market uses include flexible printed circuit board, capacitor film, film switch, automatic recording technology and microwave baking packaging materials. Another important use is packaging container. In addition, it is also a kind of industrial fiber raw material, which is expected to become an excellent rubber reinforcement material, industrial cable material, and medium monofilament for paper machine sleeve and filter.
