paraffine

/'pærәfin, -fi:n/

中文翻译

n. 石蜡, (英)火油, (美)kerosene煤油

英文解释

n. A white waxy substance, resembling spermaceti, tasteless

and odorless, and obtained from coal tar, wood tar, petroleum, etc., by

distillation. It is used as an illuminant and 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 coal gas and

kerosene consist largely of paraffins.

常见例句

-- also, by extension, any one in the homologous series of paraffine alcohols of which methyl alcohol is the type.

A substance obtained from the residues of the distillation of petroleum, essentially the same as vaseline, but of somewhat stiffer consistency, and consisting of a mixture of the higher paraffines
