Petroleum ether is also called petroleum essence. Petroleum products with distillation range of 35 ~ 80℃. It's a colorless, volatile liquid that smells like Specific gravity 0.635 ~ 0.660, boiling point 40 ~ 80℃, freezing point <-73℃. The vapor is anesthetic and inhaled in large quantities can make people unconscious or even asphyxiate. Insoluble in water, soluble in anhydrous alcohol, benzene, chloroform, ether, oil, etc. Mainly used as a solvent and oil extraction agent (6# solvent oil). In case of fire, it is very easy to burn, and it is a flammable liquid. Flash point -50 ~ 8.Chemicalbook5℃, spontaneous combustion point 246 ~ 287℃, explosion limit 1.1 ~ 6%, minimum ignition energy 0.2-0.5 milligoule. When flowing, it can carry electricity, with a resistivity of 8.4×1014 ohms · cm. When storing, fire management should be carried out according to Class A fire danger and pay attention to anti-static electricity. In case of fire, foam, dry powder, 1211 and other fire extinguishing agents can be used to extinguish the fire. Chemical reagent petroleum ether has three boiling range - 30 ~ 60℃; 60 ~ 90℃ and 90 ~ 120℃, for different molecular weight of alkane mixture, used as a solvent.
