 for Coal oil
From The Collaborative International Dictionary of English v.0.48 :

  Kerosene \Ker"o*sene`\, n. [Gr. ? wax.]
     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, having from 10 to 16 carbon atoms in each
     molecule, and having a higher boiling point (175 - 325[deg]
     C) than gasoline or the petroleum ethers, and a lower boling
     point than the oils.
