Product Detail

Petroleum ether, a light petroleum product, is a mixture of low relative molecular weight hydrocarbons (mainly pentane and hexane), colorless transparent liquids with a kerosene odor. Insoluble in water, soluble in ethanol, benzene, chloroform, oil and other organic solvents. Mainly used as a solvent and grease treatment, but volatile and fire. In laboratory column chromatography, petroleum ether (PE) and ethyl acetate (EA) are commonly used as eluents. Petroleum ether is not equal to gasoline, and at the same time, there is no ether bond (C-O-C) in its structure.

1. Cleaning agent: petroleum ether has good solubility, can dissolve and clean grease, stains, glue and lipids and other substances. It is often used to clean automotive engines, mechanical equipment, metal surfaces and so on.

2. Solvent: PE is a common solvent in the chemical industry. It can be used to dissolve and dilute resins, paints, plastics, rubber, dyes, etc. In some synthetic reactions, petroleum ether can also participate in the chemical synthesis process as an intermediate.

3. Chemical analysis: Petroleum ether is often used for standard sample preparation in chemical analysis laboratories. It can be used to extract target substances, separate mixtures, concentrate solutions, etc. In some analytical methods, chemical petroleum ether is also commonly used to extract organic pollutants from environmental samples and food samples.

4. Pharmaceutical applications: petroleum ether can be used for solvent extraction, purification and separation in pharmaceutical preparations. It can also be used as a thinner for intramuscular drugs. In addition, some oral medications also use petroleum ether to coat and encapsulate tablets.

5. Other applications: Petroleum ether can also be used in the production process of coatings, rubber products, flavors, fragrances, candles and dyes.
