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,

Petrolatum
::
Petrolatum
(n.) A
semisolid
unctuous
substance,
neutral,
and

taste or odor,
derived
from
petroleum
by
distilling
off the
lighter
portions
and
purifying
the
residue.
It is a
yellowish,
fatlike
mass,
transparent
in thin
layers,
and
somewhat
fluorescent.
It is used as a bland
protective
dressing,
and as a
substitute
for fatty
materials
in
ointments..
Undecane
::
Undecane
(n.) A
liquid
hydrocarbon,
C11H24,
of the
methane
series,
found in
petroleum;
-- so
called
from its
containing
eleven
carbon
atoms in the
molecule..
Kerosene
::
Kerosene
(n.) An oil used for
illuminating
purposes,
formerly
obtained
from the
distillation
of
mineral
wax,
bituminous
shale,
etc., and hence
called
also coal oil. It is now
produced
in
immense
quantities,
chiefly
by the
distillation
and
purification
of
petroleum.
It
consists
chiefly
of
several
hydrocarbons
of the
methane
series..
Pentadecane
::
Pentadecane
(n.) A
hydrocarbon
of the
paraffin
series,
(C15H32)
found in
petroleum,
tar oil, etc., and
obtained
as a
colorless
liquid;
-- so
called
from the
fifteen
carbon
atoms in the
molecule..
Endecane
::
Endecane
(n.) One of the
higher
hydrocarbons
of the
paraffin
series,
C11H24,
found as a
constituent
of
petroleum..

::
Naphthene
(n.) A
peculiar
hydrocarbon
occuring
as an
ingredient

Naphtha
::
Naphtha
(n.) 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..
Sodium
::
Sodium
(n.) A
common
metallic
element
of the
alkali
group,
in
nature
always
occuring
combined,
as in
common
salt, in
albite,
etc. It is
isolated
as a soft, waxy,
white,
unstable
metal,
so
readily
oxidized
that it
combines
violently
with
water,
and to be
preserved
must be kept under
petroleum
or some
similar
liquid.
Sodium
is used
combined
in many
salts,
in the free state as a
reducer,
and as a means of
obtaining
other
metals
(as
magnesium
and
aluminium)
is an
important
commercial
product.
