https://pubchem.ncbi.nlm.nih.gov/compound/hexane Another name for hexane is skellysolve-B, is that just to be silly?
It's probably considerably notorious historical trade name. In many older publications, e.g. "Skellysolve B (petroleum ether)"[1,2] appears for solvent used.
It was a product or trade name of Skelly Oil Company founded in 1919.
It's not a pure hexane, rather narrow-boiling hexane oil fraction.
I could find analysis of similar product Skellysolve C, which is C7 heptane fraction:
- 24.9% heptane
- 15.0% methylcyclohexane
- 5.5% cyclohexane
- 5.2% heavy nonaromatics
- 2.7% toluene
- 2.5% hexane
Skellysolve A is essentially n-pentane, b 28-30°/atm,
Skellysolve B is essentially n-hexane, b 60-68°/atm,
Skellysolve C is essentially n-heptane, b 90-100°/atm,
Skellysolve D is mixed heptanes, b 75-115°/atm,
Skellysolve E is mixed octanes, b 100-140°/atm,
Skellysolve F is petroleum ether, b 30-60°/atm,
Skellysolve G is petroleum ether, b 40-75°/atm,
Skellysolve H is hexanes and heptanes, b 69-96°/atm,
Skellysolve L is essentially octanes, b 95-127°/atm.
Unfortunately, Chemical Abstracts Service, mixes names for different substances, including this tradename: “n-hexane”, “hexane (all isomers)”, “Skellysolve B” under single CAS RN 110-54-3.
