Aldehyde is formed to a considerable extent during the
reaction.
_Acetic acid_ and _benzene_ are both decomposed with violence, their
cold vapors burn in fluorine, and when the latter is bubbled through
the liquids themselves, flashes of flame, and often most dangerous
explosions, occur. In the case of benzene, carbon is deposited, and
with both liquids fluorides of hydrogen and carbon are evolved.
_Aniline_ likewise takes fire in fluorine, and deposits a large
quantity of carbon, which, however, if the fluorine is in excess,
burns away completely to carbon tetrafluoride.
Such are the main outlines of these later researches of M. Moissan,
and they cannot fail to impress those who read them with the
prodigious nature of the forces associated with those minutest of
entities, the chemical atoms, as exhibited at their maximum, in so far
as our knowledge at present goes, in the case of the element
fluorine.--_Nature._
