ACTION OF FLUORINE UPON A FEW ORGANIC COMPOUNDS.
_Chloroform._--When chloroform is saturated with fluorine, and
subsequently boiled, carbon tetrafluoride, hydrofluoric acid and
chlorine are evolved. If a drop of chloroform is agitated in a glass
tube with excess of fluorine, a violent explosion suddenly occurs,
accompanied by a flash of flame, and the tube is shattered to pieces.
The reaction is very lively when fluorine is evolved in the midst of a
quantity of chloroform, a persistent flame burns beneath the surface
of the liquid, carbon is deposited, and fluorides of hydrogen and
carbon are evolved together with chlorine.
_Methyl chloride_ is decomposed by fluorine, even at -23 deg., with
production of a yellow flame, deposition of carbon, and liberation of
fluorides of hydrogen and carbon and free chlorine. With the vapor of
methyl chloride, as pointed out in the description of the
electrolysis, violent explosions occur.
_Ethyl alcohol_ vapor at once takes fire in fluorine gas, and the
liquid is decomposed with explosive violence without deposition of
carbon.
