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. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

The original product, up to circa 2006, came in two versions - "All Purpose" and "Master Craftsman". The active and main ingredient of both the original Nitromors versions was dichloromethane (also known as methylene chloride) accompanied by a smaller proportion of methanol. This product was recommended by the Guild of Master Craftsmen and the ...
Some haloalkanes are still widely used for industrial cleaning, such as methylene chloride (dichloromethane), and as refrigerants, such as R-134a (1,1,1,2-tetrafluoroethane). Haloalkenes have also been used as solvents, including perchloroethylene (Perc, tetrachloroethene), widespread in dry cleaning, and trichloroethylene (TCE, 1,1,2 ...
Despite the similar names, the anaesthetic mixture named "bichloride of methylene" did not contain the actual compound that would be called bichloride of methylene (Dichloromethane CH 2 Cl 2). Instead, it was later discovered as a mixture of chloroform and alcohol marketed as the bichloride of methylene and even given the formula CH 2 Cl 2. [12]
Collins reagent is a solution of the same CrO 3 (pyridine) 2 but in dichloromethane. The Ratcliffe variant of Collins reagent relates to details of the preparation of this solution, i.e., the addition of chromium trioxide to a solution of pyridine in methylene chloride. [3]
The American Chemistry Council, the industry’s top lobbying group, describes methylene chloride as “an essential compound” used to make many products and goods that Americans rely on every ...
The dichloromethane with a low boiling point (39.6 °C (103.3 °F) under standard pressure p o = 10 5 Pa – as the drinking bird is first evacuated, partially filled and sealed, the pressure and thus the boiling point in the drinking bird will be different), gives the heat engine the ability to extract motion from low temperatures. The ...
