Petroleum ether is the petroleum fraction consisting of aliphatic hydrocarbons and boiling in the range 35–60 °C, and commonly used as a laboratory solvent. Despite the name, petroleum ether is not an ether; the term is used only figuratively, signifying extreme lightness and volatility.
Petroleum ether is a light, volatile, petroleum fraction predominantly composed of aliphatic hydrocarbons. Available in various quantities and reagent grades, it is a common liquid hydrocarbon solvent that does not actually contain ether functional groups.
For petroleum crude oil, do not spray water directly into a breached tank car. This can lead to a dangerous boil over. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
Petroleum ether, also known as benzine, X4 or Ligroin, is a group of various volatile, highly flammable, liquid hydrocarbon mixtures used chiefly as nonpolar solvents . Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene.
Petroleum ether mixtures are expected to biodegrade rapidly in soil and water under aerobic conditions. In air, they react with photochemically produced hydroxyl radicals with an estimated half-life of 3–8 days.
The mechanism of toxicity from long-term overexposure to petroleum ether is dependent on the chemical makeup of the distillate. For example, if peripheral neuropathy is observed, it is most likely due to a high concentration of n-hexane in the petroleum ether. n-Hexane is known to cause axonal damage in peripheral nerves.
Feb 28, 2017 · Abstract. This monograph for Petroleum Ether provides, in addition to common physical constants, a general description including typical appearance and applications. The monograph also details the following specifications and corresponding tests for verifying that a substance meets ACS Reagent Grade specifications including: Color (APHA ...
