WebDichloromethane (often abbreviated to DCM) is a volatile and non-flammable compound that is commonly used as an organic solvent in several applications on the industrial and laboratory scale. This compound is often referred to as methylene chloride due to its high volatility and ability to dissolve compounds. Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH2Cl2. 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 slightly polar, and miscible with many … See more Natural sources of dichloromethane include oceanic sources, macroalgae, wetlands, and volcanoes. However, the majority of dichloromethane in the environment is the result of industrial emissions. See more DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings. … See more Even though DCM is the least toxic of the simple chlorohydrocarbons, it has serious health risks.
