How dense is dichloromethane
WebEmily James. As an organic chemist, I’ve had a lot of exposure to organic solvents, especially the popular dichloromethane, also known as DCM or methylene chloride. Dichloromethane is a volatile, colourless liquid, with a mildly sweet, not unpleasant odour. It’s immiscible with water but can dissolve a wide range of organic compounds. WebDichloromethane (DCM) is a fantastically useful solvent. It can dissolve a huge variety of compounds; whisk them through chromatography columns; and then Rotovap away in a trice. Yet it also has a dark side. DCM has raised health concerns for years: the US Environmental Protection Agency judges it a ‘probable human carcinogen’, for example.
