产品性能:
Product performance:
1、 灰白色粉状或片状结晶,有特殊气味,易升华。不溶于水,溶于无水乙醇,稳定性,稳定;危险标记:8(易燃固体)对皮肤有刺激性。
1. Gray white powder or flake crystal, with special smell, easy to sublimate. Insoluble in water, soluble in absolute ethanol, stable and stable; Hazard sign: 8 (flammable solid) is irritating to skin.
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(20/4℃),0.9625(100/4℃),折射率:1.5898
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 (20/4 ℃), 0.9625 (100/4 ℃), refractive index: 1.5898
3、 易燃烧,由于含碳量高,燃烧时火焰光弱而烟大。
3. It is easy to burn. Due to the high carbon content, the flame is weak and smoky when burning.
4、 熔点较低,数低熔点固体物质。常温下呈固态,受热熔化。应远离热源。
4. Low melting point, several low melting point solid materials. It is solid at room temperature and melts when heated. Keep away from heat sources.
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。
5. It is easy to react with oxidants and mixed acid substances. It shall not be mixed with food raw materials, oxidants and acids.
6、 1g精萘可溶于13ml甲醇或乙醇,3.5ml苯或甲苯,2ml氯仿或四氯化碳,1.2ml二硫化碳。不溶于水。精萘亦能和水蒸气一同挥发。与空气形成爆炸混合物、爆炸极限0.9%-5.9%(体积)。
6. 1g refined naphthalene is soluble in 13ml methanol or ethanol, 3.5ml benzene or toluene, 2ml chloroform or carbon tetrachloride, 1.2ml carbon disulfide. Insoluble in water. Refined naphthalene can also volatilize with water vapor. Forming explosive mixture with air, explosive limit 0.9% - 5.9% (volume).
