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

Phlorone :: Phlorone (n.) A yellow crystalline substance having a peculiar unpleasant odor, resembling the quinones, and obtained from beechwood tar and coal tar, as also by the oxidation of xylidine; -- called also xyloquinone..
