- Dichloromethane or
methylene chloride is the chemical compound with the formula CH2Cl2.
- DCM is widely used
as a solvent, the general view being that it is one of the less harmful
of the chlorocarbons
- DCM will dissolve in
most organic solvents although it is not miscible with water
- Methylene chloride
is a highly volatile solvent used widely in paint removers, aerosol
products and as a process solvent in the chemical and pharmaceutical
industries.
- Methylene chloride
is produced either by the chlorination of methane, or by the
hydrochlorination of methanol to methyl chloride with the
subsequent
chlorination of methyl chloride.
- Oxyhydrochlorination, produces methylene chloride in
addition to methyl chloride,is a potential beginning to a gas-to-liquid
fuels process.
- The former process
used for paint stripping was to immerse the parts in a heated tank
containing a methylene chloride based stripping solution.
- A sealing layer of
paraffin oil on the surface of the solvent was used to minimize
evaporative losses.
- Methylene chloride
is used as a solvent in paint strippers, adhesives, water proof
membranes and for general flushing; in cold tank degreasing urethane
foam manufacturing print developing; detergents; as a laboratory
solvent; and aerosol filler and gardening aerosol.
- Methylene Chloride
is used to decaffeinate coffee and to prepare extracts of hops and other
flavorings in the food industry.
- DCM is used as an
aerosol spray propellant and as a blowing agent for polyurethane
foams.
- The tablet
granulation and coating operations required the use of significant
amounts of methylene chloride, acetone, ethanol, and isopropyl
alcohol.
- Methylene chloride
is included in the Australian High Volume Industrial Chemicals
List.
- The list compiled
with industrial chemicals that are manufactured and imported
.
- The remediation
process activated by SPH used a combination of cleanup mechanisms,
including vapor extraction, steam stripping, biological decomposition,
and thermally enhanced methylene chloride degradation.
- According to experts
methylene chloride, leading to formal or informal measures against
chlorinated substances.
- Chemical substitutes
for methylene chloride with less impact on health and
environment.
- Several industrial
organisations tend to stress that particularly for the infrequent
consumer exposures the risks of DCM are minimal, and that the
alternative solvents are not as well researched.
- DCM is used as an
aerosol spray propellant and as a blowing agent for polyurethane
foams
- Nitrobenzene also is
used as a solvent in petroleum refining and the synthesis of other
organic compounds, such as acetaminophen.
