Lubricants and for medicinal purposes (think Vaseline)
Chemicals around WWI, lighter to heavier grades, as well as less explosive at room temps.
Cymogene : Its specific gravity is around .589, mostly Butane, C5 H10 and Pentane C5 H12 evaporates faster than ether. local anaesthetic
Rhigoline : A mixture of volatile hydrocarbons intermediate between Cymogene and Gasoline. Its specific gravity is .61 used as a local anaesthetic. Consists largely of Pentane, C 5 H 12
variants of this was used for Dry Cleaning before replaced by Naphtha, then Carbon Tetrachloride and in turn Trichloroethylene for safety reasons
Straight run Gasoline : specific gravity is around 0.72 C6 thru C9 It's really a blend of C5 H12 Pentane, C6 H14 Hexane, C7 H16 Heptane and C8 H18 Octane, depending on base stock of Crude
Naphtha, 'White' Gasoline : specific gravity is around 0.76 C10 H22. Stoves and lanterns, as well as non staining cleaning fluid
You can make refrigeration with those as the working fluid, just isn't very safe
