  • 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.
