Richard:
Petroleum ether is a purified (mostly) saturated hydrocarbon blend. In
other words, a higher boiling fraction than propane or butane. It consists
of pentanes, hexanes, heptanes, and probably octanes. It is a common
laboratory solvent. I am not sure where you can get it outside of a lab.
There are three fractions defined by boiling points: 30 - 60, 60 - 80, and
80 - 110 degree ranges. These can be referred to as Skellysolvs A, B, C
