WebDichloromethane. Formula: CH2CI2 CAS: 75-09-2. Dichloromethane Detection: Dichloromethane is highly volatile and should be stored in a cool, dry area in tightly closed, labeled containers. This chemical needs to be kept away from metals, light, and any source of heat or ignition. DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and … See more 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 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 See more Even though DCM is the least toxic of the simple chlorohydrocarbons, it has serious health risks. Its high volatility makes it an acute inhalation hazard. It can also be absorbed through … See more Ozone Dichloromethane is not classified as an ozone-depleting substance by the Montreal Protocol. The U.S. Clean Air Act does not regulate dichloromethane as an ozone depleter. Recent research shows that dichloromethane … 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 Dichloromethane is widely used as a solvent in part because it is relatively inert. It does participate in reactions with certain strong nucleophiles however.
