　　適用范圍:它是一種典型的有機(jī)化工原料，廣泛應(yīng)用于染料行業(yè)中間體、氨基甲酸脂類殺蟲劑、1-萘酚、2-萘酚、H酸、周位酸、氨基C酸、甲酚等樹脂、橡膠、溶劑、分別劑等。屬芳香烴類，是工業(yè)上重要的稠環(huán)烴。

　　Scope of application: It is a typical organic chemical raw material widely used in the dye industry as an intermediate, amino acid ester insecticide, 1-naphthol, 2-naphthol, H-acid, cyclic acid, amino C-acid, cresol and other resins, rubber, solvents, dispersants, etc. Belonging to aromatic hydrocarbons, it is an important polycyclic hydrocarbon in industry.

　　產(chǎn)品性能;1、灰白色粉狀或片狀結(jié)晶，有特別氣味，易升華。不于水，溶于無水乙醇，牢固性，牢固;危險標(biāo)志:8(易燃固體)對皮膚有刺激性。2、比重:1.162;熔點(diǎn):80.℃:沸點(diǎn):217.9℃;閃點(diǎn):(開杯)78.89℃;燃點(diǎn):86℃;自然點(diǎn):526.11℃;相對密度:1.145(2014℃),0.9625(1004℃)，折射率:1.58983、易燃燒，因為含碳量高，燃燒時火焰光弱而煙大。

　　Product performance; 1. Gray white powdery or flaky crystals with a distinctive odor and easy sublimation. Not soluble in water, soluble in anhydrous ethanol, firm, sturdy; Danger sign: 8 (flammable solid) is irritating to the skin. 2. Specific gravity: 1.162; Melting point: 80 ℃; Boiling point: 217.9 ℃; Flash point: (open cup) 78.89 ℃; Ignition point: 86 ℃; Natural point: 526.11 ℃; Relative density: 1.145 (2014 ℃), 0.9625 (1004 ℃), refractive index: 1.58983, easy to burn, due to high carbon content, the flame light is weak and the smoke is large during combustion.

　　4、熔點(diǎn)較低，數(shù)低熔點(diǎn)固體物質(zhì)。常溫下呈固態(tài)，受熱融化。應(yīng)遠(yuǎn)離熱源。5、易與氧化劑和混酸物質(zhì)發(fā)生反應(yīng)。不得與食品原料、氧化劑、酸類物質(zhì)混裝、混放。6、1g 精萘可溶于 13m|甲醇或乙醇，3.5m苯或甲苯，2ml 氣仿或四氯化碳，1.2ml二硫化碳。不溶于水。精萘亦能和水蒸氣一同揮發(fā)。與空氣形成爆炸混雜物、爆炸極限0.9%-5.9%(體積)。

　　4. Low melting point, a solid substance with a low melting point. It is solid at room temperature and melts when heated. Keep away from heat sources. 5. Easy to react with oxidants and mixed acid substances. Do not mix or store with food ingredients, oxidants, or acidic substances. 6. 1g of refined naphthalene can be dissolved in 13ml of methanol or ethanol, 3.5ml of benzene or toluene, 2ml of gaseous or carbon tetrachloride, and 1.2ml of carbon disulfide. Insoluble in water. Naphthalene can also evaporate together with water vapor. Form explosive mixtures with air, with an explosive limit of 0.9% -5.9% by volume.
