Webジクロロメタン (dichloromethane) は、分子式を CH 2 Cl 2 と表される、有機溶媒の一種。 慣用名は塩化メチレンといい、産業界ではこちらの名称を使うことも多い。DCM … 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 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. … See more 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 … 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.
