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. Its high volatility makes it an acute inhalation hazard. It can also be absorbed through the skin. Symptoms of acute overexposure to dichloromethane via inhalation … See more • Chloromethane • Trichloromethane • Tetrachloromethane • List of organic compounds • Carbon monoxide-releasing molecules 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.

WebFor instance, a solvent that weighs 0.68 g/mL has a specific gravity of 0.68. When an organic solvent is mixed with water, after settling the organic solvent will be on top if it has a density less than 1.00, and on the bottom if it has a density greater than 1.00. The four most common solvents used in the teaching labs are listed in Table 11-3. WebAug 4, 2011 · DCM is also an excellent solvent for convenient reasons like being more dense than water so it will be on the bottom in a separatory funnel if you do an aqueous workup and it is also easy to evaporate.
