haohan石油醚试剂50g

Petroleum ether is a colorless transparent liquid, kerosene smell. Mainly a mixture of pentane and hexane. Insoluble in water, soluble in ethanol, benzene, chloroform, oil and other organic solvents. Flammable and explosive, and strong reaction with oxidants. Mainly used as solvent and grease treatment. Usually with platinum reforming raffinate oil or straight-run gasoline by fractionation, hydrogenation or other methods. Generally have 30 ~ 60 ℃, 60 ~ 90 ℃, 90 ~ 120 ℃ and other boiling range specifications. Petroleum ether is not equal to gasoline, at the same time, its structure does not have ether bond (C-O-C).
