6. 萘是农药生产中的一种原料，可以制造成甲萘酚、乙萘酚，也可以氧化成苯二甲酸酐，进一步生成苯二甲酰亚胺，也可以与氯乙酸生成萘乙酸。可作为杀虫剂亚胺硫磷、甲萘威，除草剂灭草松、敌草胺，植物生长调节剂萘乙酸和萘氧乙酸等的中间体。

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. 萘是工业上重要的稠环烃，主要用于生产苯酐、各种萘酚、萘胺等，是生产合成树脂、增塑剂、染料的中间体、表面活性剂、合成纤维、涂料、农药、医药、香料、橡胶助剂和杀虫剂的原料。萘的用途分配，各国有所不同。用于生产苯酐的大致占70%，用于染料中间体和橡胶助剂的约占15%，杀虫剂的约占6%，鞣革剂的约占4%。美国用于生产杀虫剂的比例较大，主要是用于生产西维因。以萘为原料，经过磺化、硝化、还原、胺化、水解等单元操作，可制得多种中间体。精萘的应用还在拓宽，新产品“超级塑性材料”即萘磺酸盐甲醛缩合物，可用作水泥添加剂，增加混凝土的塑性变形而不降低其强度。今后几年需求量将以5-10%的速度增长。

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.
