📘 English Definition(英文释义)
  1. n. A white waxy substance, resembling spermaceti, tasteless
  2. and odorless, and obtained from coal tar, wood tar, petroleum, etc., by
  3. distillation. It is used as an illuminant and lubricant. It is very
  4. inert, not being acted upon by most of the strong chemical reagents. It
  5. was formerly regarded as a definite compound, but is now known to be a
  6. complex mixture of several higher hydrocarbons of the methane or
  7. marsh-gas series; hence, by extension, any substance, whether solid,
  8. liquid, or gaseous, of the same chemical series; thus coal gas and
  9. kerosene consist largely of paraffins.
