Methylene Chloride
is a clear, colorless, nonflammable, volatile liquid chlorinated hydrocarbon with a sweet, pleasant smell and emits highly toxic fumes of
phosgene
when heated to decomposition. Methylene chloride is primarily used as a solvent in paint removers, but is also used in aerosol formulations, as a solvent in the manufacture of pharmaceuticals, as a degreasing agent, in electronics manufacturing and as an
ethane
foam blowing agent. Inhalation exposure to this substance irritates the nose and throat and affects the central nervous system. Methylene chloride is a possible mutagen and is reasonably anticipated to be a human carcinogen. (NCI05)
Dichloromethane
(
DCM
or
methylene chloride
) is an
organochloride
compound with the
formula
C
H
2
Cl
2
. This colorless, volatile liquid with a
chloroform
-like, sweet odour is widely used as a
solvent
. Although it is not
miscible
with water, it is
polar
, and miscible with many organic
solvents
.
DCM
is produced by
treating
either
chloromethane
or
methane
with chlorine gas at 400-500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993.
The output of these processes is a mixture of chloromethane, dichloromethane,
chloroform
, and
carbon tetrachloride
as well as hydrogen chloride as a byproduct. These compounds are separated by
distillation
.
DCM
was first prepared in 1839 by the
French
chemist
Henri Victor Regnault
(1810-1878), who isolated it from a mixture of
chloromethane
and
chlorine
that had been exposed to
sunlight
.
Dichloromethane appears as a colorless liquid with a sweet, penetrating, ether-like odor. Noncombustible by if exposed to high temperatures may emit toxic
chloride
fumes. Vapors are narcotic in high concentrations. Used as a solvent and paint remover.
