6. Naphthalene is a raw material in pesticide production, which can be manufactured into naphthol and ethylnaphthol, or oxidized to phthalic anhydride, further generating phthalimide, or reacting with chloroacetic acid to form naphthoic acid. It can be used as an intermediate for insecticides such as imidophos and carbendazim, herbicides such as glyphosate and diclofenac, and plant growth regulators such as naphthylacetic acid and naphthoxyacetic acid.

7. 萘是工業(yè)上重要的稠環(huán)烴，主要用于生產(chǎn)苯酐、各種萘酚、萘胺等，是生產(chǎn)合成樹(shù)脂、增塑劑、染料的中間體、表面活性劑、合成纖維、涂料、農(nóng)藥、醫(yī)藥、香料、橡膠助劑和殺蟲(chóng)劑的原料。萘的用途分配，各國(guó)有所不同。用于生產(chǎn)苯酐的大致占70%，用于染料中間體和橡膠助劑的約占15%，殺蟲(chóng)劑的約占6%，鞣革劑的約占4%。美國(guó)用于生產(chǎn)殺蟲(chóng)劑的比例較大，主要是用于生產(chǎn)西維因。以萘為原料，經(jīng)過(guò)磺化、硝化、還原、胺化、水解等單元操作，可制得多種中間體。精萘的應(yīng)用還在拓寬，新產(chǎn)品“超級(jí)塑性材料”即萘磺酸鹽甲醛縮合物，可用作水泥添加劑，增加混凝土的塑性變形而不降低其強(qiáng)度。今后幾年需求量將以5-10%的速度增長(zhǎng)。

7. Naphthalene is an important polycyclic hydrocarbon in industry, mainly used for the production of phthalic anhydride, various naphthols, naphthylamines, etc. It is an intermediate in the production of synthetic resins, plasticizers, dyes, surfactants, synthetic fibers, coatings, pesticides, pharmaceuticals, fragrances, rubber additives, and insecticides. The allocation of uses of naphthalene varies among countries. Approximately 70% are used for the production of phthalic anhydride, 15% are used as dye intermediates and rubber additives, 6% are used as insecticides, and 4% are used as tanning agents. The United States has a large proportion of insecticides used for production, mainly for the production of carbapenem. Various intermediates can be produced from naphthalene through unit operations such as sulfonation, nitrification, reduction, amination, and hydrolysis. The application of refined naphthalene is still expanding, and the new product "superplastic material", namely naphthalene sulfonate formaldehyde condensate, can be used as a cement additive to increase the plastic deformation of concrete without reducing its strength. The demand will grow at a rate of 5-10% in the coming years.
