fr. L. petra a rock + oleum oil: cf. F. p['e]trole. Cf.
Petrify, and Oil.]
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.
[1913 Webster]
Petroleum spirit, a volatile liquid obtained in the
distillation of crude petroleum at a temperature of
170[deg] Fahr., or below. The term is rather loosely
applied to a considerable range of products, including
benzine and ligroin. The terms petroleum ether, and
naphtha, are sometimes applied to the still more volatile
products, including rhigolene, gasoline, cymogene, etc.

naphtha, Gr. na`fqa, fr.Ar. nafth, nifth.]
1. (Chem.) 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.
[1913 Webster]
2. (Chem.) 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.
[1913 Webster]
Note: This term was applied by the earlier chemical writers
to a number of volatile, strong smelling, inflammable
liquids, chiefly belonging to the ethers, as the
sulphate, nitrate, or acetate of ethyl. --Watts.
[1913 Webster]
Naphtha vitrioli [NL., naphtha of vitriol] (Old Chem.),
common ethyl ether; -- formerly called sulphuric ether.
See Ether.

petroleum benzine
(gcide) | Benzine \Ben"zine\, n. [From Benzoin.] (Chem.)
1. A liquid consisting mainly of the lighter and more
volatile hydrocarbons of petroleum or kerosene oil, used
as a solvent and for cleansing soiled fabrics; -- called
also petroleum spirit, petroleum benzine. Varieties or
similar products are gasoline, naphtha, rhigolene,
ligroin, etc.
[1913 Webster]
2. Same as Benzene. [R.]
[1913 Webster]
Note: The hydrocarbons of benzine proper are essentially of
the marsh gas (paraffin) series, while benzene proper
is the typical hydrocarbon of the aromatic series.
