Paraffin   /pˈɛrəfən/   Listen
noun
Paraffine, Paraffin  n.  (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. Note: In the present chemical usage this word is spelled paraffin, but in commerce it is commonly spelled paraffine.
Native paraffin. See Ozocerite.
Paraffin series. See Methane series, under Methane.

It follows therefore that two hydrocarbon radicals are bound to the carbon monoxide residue with the same strength as they combine ...

... strong, his line heavy, though tapered, and his gut well selected and stained. The fly-book stamps the fisherman even more truly than the topboot stamps the fox-hunter. Nor does the accomplished expert with the dry fly disdain with fat of deer to grease his line, nor with paraffin to dress his fly and make it float. But he keeps the paraffin in a leather case by itself, so that his coat may not remain redolent for months. From top to toe he is a fisherman. His boots are thick, even though he does not require waders; ...
