Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

Another source of poisoning is exposure to the organic solvent dichloromethane, also known as methylene chloride, found in some paint strippers, [89] as the metabolism of dichloromethane produces carbon monoxide. [90] [91] [52] In November 2019, an EPA ban on dichloromethane in paint strippers for consumer use took effect in the United States. [92]

The output of this process is a mixture of the four chloromethanes: chloromethane, methylene chloride (dichloromethane), trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). These can then be separated by distillation .
Dichloromethane is the most important halomethane-based solvent. Its volatility, low flammability, and ability to dissolve a wide range of organic compounds makes this colorless liquid a useful solvent. [2] It is widely used as a paint stripper and a degreaser.
