Did you know?
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.
