Description
Petroleum Ether is a light petroleum product with a boiling range of 30 ~ 150 ℃, which is mainly composed of Pentane and Hexane. The collected temperature range is generally about 30 ℃, and generally has boiling range specifications of 30 ~ 60 ℃, 60 ~ 90 ℃, 90 ~ 120 ℃. Although the name has “Ether”, it is a mixture containing many hydrocarbons, which is different from ethers containing oxygen.
Chemical Property
Colorless and highly flammable transparent liquid with kerosene smell. The relative density is about 0.63 ~ 0.66. Insoluble in water, soluble in anhydrous ethanol, chloroform, benzene, oil and other most organic solvents. It is mainly composed of pentane and hexane, and also contains a small amount of unsaturated hydrocarbons. Volatile, polar 0.01, is a weak polar organic solvent, which is often mixed with strong polar organic solvents to form a developing agent for thin-layer chromatography and an eluent for column chromatography.
Applications
Petroleum Ether is mainly used as a solvent to extract oil or as a solvent and developing agent for chromatographic analysis, and as an extractant in medicine and pesticide production.
