Ph of heptane
WebPetroleum 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 classified as an ether; the term is used only figuratively, signifying extreme lightness and volatility. WebHeptane ( n -Heptane) is a linear hydrocarbon. Its cetane number has been reported to be 56. [ 1] Application Greener alternatives to Hexane in HPLC. Heptane ( n -heptane) may be used to compose the solvent mixtures for the purification of N -acylpyrrolidine derivatives of fatty acid methyl esters (FAMEs) by TLC (Thin Layer Chromatography). [ 2]
