產(chǎn)品性能:
Product performance:
1、灰白色粉狀或片狀結(jié)晶,有特殊氣味,易升華。不溶于水,溶于無水乙醇,穩(wěn)定性,穩(wěn)定;危險(xiǎn)標(biāo)記:8(易燃固體)對皮膚有刺激性。
1. Gray white powder or flake crystal, with special smell, easy to sublimate. Insoluble in water, soluble in absolute ethanol, stable and stable; Danger sign: 8 (flammable solid) irritating to skin.
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(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、易燃燒,由于含碳量高,燃燒時火焰光弱而煙大。
3. It is easy to burn. Due to the high carbon content, the flame is weak and smokey when burning.
4、熔點(diǎn)較低,數(shù)低熔點(diǎn)固體物質(zhì)。常溫下呈固態(tài),受熱熔化。應(yīng)遠(yuǎn)離熱源。
4. Low melting point, a few low melting point solid substances. It is solid at room temperature and melts when heated. Keep away from heat sources.
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。
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。精萘亦能和水蒸氣一同揮發(fā)。與空氣形成爆炸混合物、爆炸極限0.9%-5.9%(體積)。
6. 1g refined naphthalene is soluble in 13ml methanol or ethanol, 3.5ml benzene or toluene, 2ml chloroform or carbon tetrachloride, and 1.2ml carbon disulfide. Insoluble in water. Refined naphthalene can also volatilize with water vapor. Form explosive mixture with air, explosion limit 0.9% - 5.9% (volume).
