paraffin    音標拼音: [p'ɛrəfən]
n. 石蠟

石蠟

paraffin
n 1: from crude petroleum; used for candles and for preservative
or waterproof coatings [synonym: {paraffin}, {paraffin wax}]
2: a series of non-aromatic saturated hydrocarbons with the
general formula CnH(2n2) [synonym: {methane series}, {alkane
series}, {alkane}, {paraffin series}, {paraffin}]
3: (British usage) kerosine [synonym: {paraffin}, {paraffin oil}]

Paraffin \Par"af*fin\ (p[a^]r"[a^]f*f[i^]n), Paraffine
\Par"af*fine\ (p[a^]r"[a^]f*f[i^]n or p[a^]r"[a^]f*f[=e]n), n.
[F. paraffine, fr. L. parum too little affinis akin. So
named in allusion to its chemical inactivity.] (Chem.)
A white waxy substance, resembling spermaceti, tasteless and
odorless, and obtained from coal tar, wood tar, petroleum,
etc., by distillation. It is used in candles, as a sealing
agent (such as in canning of preserves), as a waterproofing
agent, as an illuminant and as a lubricant. It is very inert,
not being acted upon by most of the strong chemical reagents.
It was formerly regarded as a definite compound, but is now
known to be a complex mixture of several higher hydrocarbons
of the methane or marsh-gas series; hence, by extension, any
substance, whether solid, liquid, or gaseous, of the same
chemical series; thus gasoline, coal gas and kerosene consist
largely of paraffins.
[1913 Webster PJC]

Note: In the present chemical usage this word is spelled
paraffin, but in commerce it is commonly spelled
paraffine.
[1913 Webster]

{Native paraffin}. See {Ozocerite}.

{Paraffin series}. See {Methane series}, under {Methane}.
[1913 Webster]
