精萘的主要应用领域是染料及有机颜料中间体，产量大的是2-萘酚和H酸。我国已成为世界上大的染料和有机颜料生产国，近年来生产技术和产品结构变化较大，但对精萘的需求总体呈平稳增长趋势。

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.

萘在农用化学品和医药领域也有重要应用，这也是萘消费中增长快的部分。主要产品包括植物生长调节剂和除草剂、熏蒸剂、鞣革剂、饲料添加剂、计生药品等。此外，以萘为原料还可生产一种重要的功能高分子材料聚萘二甲酸乙二醇酯(PEN)，该产品早期市场主要是薄膜，潜在的市场用途包括柔性印刷线路板、电容器膜、薄膜开关、自动记录技术和可微波烘烤包装材料等。另一种重要用途就是包装容器，此外它还是一种工业用纤维原料，有望成为优良的橡胶增强材料、工业电缆料以及造纸机套和过滤器用介质单丝等。

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.
