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 .
Chlorinated brake cleaners (often sold as non-flammable) [2] use organochlorides like tetrachloroethylene and dichloromethane. [3] [4] Historically 1,1,1-Trichloroethane was used, sometimes together with Tetrachloroethylene. It was phased out because of its ozone-depleting nature. [5]

Controlling gas and vapor concentrations outside the flammable limits is a major consideration in occupational safety and health. Methods used to control the concentration of a potentially explosive gas or vapor include use of sweep gas, an unreactive gas such as nitrogen or argon to dilute the explosive gas before coming in contact with air.
Most organic solvents are flammable or highly flammable, depending on their volatility. Exceptions are some chlorinated solvents like dichloromethane and chloroform. Mixtures of solvent vapors and air can explode. Solvent vapors are heavier than air; they will sink to the bottom and can travel large distances nearly undiluted.
The FDA has one regulation allowing for the use of methylene chloride as a solvent to decaffeinate coffee, stipulating that “the residues of methylene chloride must not exceed 10 parts per ...
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.
Jennifer Lopez opened up in a new interview with British Vogue, discussing how she approaches “hardships” in the wake of her divorce from Ben Affleck.
