- Crude oil
- Fossil fuel
- Fuel for most cars
- Rock oil, mineral oil, or natural oil, a dark brown or
greenish inflammable liquid, which, at certain points, exists in the
upper strata of the earth, from whence it is pumped, or forced by
pressure of the gas attending it. It consists of a complex mixture of
various hydrocarbons, largely of the methane series, but may vary much
in appearance, composition, and properties. It is refined by
distillation, and the products include kerosene, benzine, gasoline,
paraffin, etc.
- Passes out
- Swoons
- The impure spirit which comes over first and last in the
distillation of whisky; -- the former being called the strong faints,
and the latter, which is much more abundant, the weak faints. This
crude spirit is much impregnated with fusel oil.
- The complex mixture of volatile, liquid, inflammable
hydrocarbons, occurring naturally, and usually called crude petroleum,
mineral oil, or rock oil. Specifically: That portion of the distillate
obtained in the refinement of petroleum which is intermediate between
the lighter gasoline and the heavier benzine, and has a specific
gravity of about 0.7, -- used as a solvent for varnishes, as a
carburetant, illuminant, etc.
- One of several volatile inflammable liquids obtained by
the distillation of certain carbonaceous materials and resembling the
naphtha from petroleum; as, Boghead naphtha, from Boghead coal
(obtained at Boghead, Scotland); crude naphtha, or light oil, from coal
tar; wood naphtha, from wood, etc.
