　　Jingtu

　　适用范围:它是一种典型的有机化工原料，广泛应用于染料行业中间体、氨基甲酸脂类杀虫剂、1-萘酚、2-萘酚、H酸、周位酸、氨基C酸、甲酚等树脂、橡胶、溶剂、分别剂等。属芳香烃类，是工业上重要的稠环烃。

　　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.

　　产品性能;1、灰白色粉状或片状结晶，有特别气味，易升华。不于水，溶于无水乙醇，牢固性，牢固;危险标志:8(易燃固体)对皮肤有刺激性。2、比重:1.162;熔点:80.℃:沸点:217.9℃;闪点:(开杯)78.89℃;燃点:86℃;自然点:526.11℃;相对密度:1.145(2014℃),0.9625(1004℃)，折射率:1.58983、易燃烧，因为含碳量高，燃烧时火焰光弱而烟大。

　　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、熔点较低，数低熔点固体物质。常温下呈固态，受热融化。应远离热源。5、易与氧化剂和混酸物质发生反应。不得与食品原料、氧化剂、酸类物质混装、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。精萘亦能和水蒸气一同挥发。与空气形成爆炸混杂物、爆炸极限0.9%-5.9%(体积)。

　　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.
