Editing Hexane (section)

==Production==
Hexane is chiefly obtained by [[oil refinery|refining]] [[petroleum|crude oil]]. The exact composition of the fraction depends largely on the source of the oil (crude or reformed) and the constraints of the refining.<ref>{{Cite journal |last1=Le Van Mao |first1=R. |last2=Melancon |first2=S. |last3=Gauthier-Campbell |first3=C. |last4=Kletnieks |first4=P. |date=2001-05-01 |title=Selective deep catalytic cracking process (SDCC) of petroleum feedstocks for the production of light olefins.
