Petroleum Ethers Ligroine Low Boiling Point Naphthas 8032 32 4

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 generally a mixture of low boiling aliphatic hydrocarbons mainly hexane and pentane. It is generally used as a laboratory solvent and also as an extraction solvent.
Petroleum ether has been used for the analysis of total dietary fiber content by employing a total dietary fibre assay kit. It may be used in the absorption chromatographic purification of organic compounds.
