'''Petroleum ether''' is the [[petroleum]] fraction consisting of [[aliphatic]] [[hydrocarbon]]s and boiling in the range 35–60&nbsp;°C, and commonly used as a laboratory [[solvent]].<ref>{{citation | editor=David R. Lide | title=[[CRC Handbook of Chemistry and Physics]] | edition=90th | year=2010 | publisher=CRC Press | pages=2–60}}</ref> Despite the name, petroleum ether is not an [[ether]]; the term is used only figuratively, signifying extreme lightness and volatility.
