Description

A mixture of C₆-C₁₀ aliphatic hydrocarbons, it is a colorless, volatile liquid with a gasoline-like odor. Its boiling range typically falls between 60-90°C, and it is highly flammable, forming explosive vapor-air mixtures.

Petroleum ether, a petroleum distillation fraction, is a mixture of low molecular weight aliphatic hydrocarbons (mostly pentanes and hexanes) with a low boiling range, typically around 30-60oC. Its name is derived from its origin and its ease of evaporation.The majority components include paraffins, olefins, naphthenes, aromatics, and about 10%–40% ethyl alcohol。Petroleum ether is commonly used as a nonpolar solvent for oils, fats, and waxes. Petroleum ether is used in pharmaceutical industries as a solvent to isolate compounds, e.g. petroleum ether can extract stigmasterol and beta-sitosterol from the aerial parts of Ageratum conyzoides and compounds with immunomodulatory activity from Anacyclus pyrethrum. It is also used as a detergent, a fuel, insecticide, in paints and varnishes, and in photography.

Petroleum ether is a colorless liquid. Extracts of leaves of Litchi chinensis Gaertn. (Sapindaceae) have been prepared in petroleum ether and were evaluated for antiinflammatory, analgesic and antipyretic activities. Pentanes and hexanes are the major constituents of petroleum ether.

Gasoline or kerosene

Air and Water Reactions：

Highly flammable. Insoluble in water.

Reactivity Profile：

PETROLEUM NAPHTHA, [FLAMMABLE LIQUID LABEL] may be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted material and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, burns exothermically to produce mostly carbon dioxide and water.

Autoignition Temperature：

475 °F

Critical Temperature & Pressure：

Store at room temperature.
