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.

log 10 of Dichloromethane vapor pressure. Uses formula: log e P m m H g = {\displaystyle \scriptstyle \log _{e}P_{mmHg}=} log e ( 760 101.325 ) − 10.08632 log e ( T + 273.15 ) − 6030.610 T + 273.15 + 80.87786 + 9.812512 × 10 − 6 ( T + 273.15 ) 2 {\displaystyle \scriptstyle \log _{e}({\frac {760}{101.325}})-10.08632\log _{e ...
The dependence on m correlates with the oxidation state of the central atom, X: the higher the oxidation state the stronger the oxyacid. For example, pK a for HClO is 7.2, for HClO 2 is 2.0, for HClO 3 is −1 and HClO 4 is a strong acid (pK a ≪ 0). [7]
Deuterated chloroform is commercially available. It is more easily produced and less expensive than deuterated dichloromethane. [4] Deuterochloroform is produced by the reaction of hexachloroacetone with deuterium oxide, using pyridine as a catalyst. The large difference in boiling points between the starting material and product facilitate ...
Chloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula CH 3 Cl.One of the haloalkanes, it is a colorless, sweet-smelling, flammable gas.
1,1-Dichloroethane is a chlorinated hydrocarbon.It is a colorless oily liquid with a chloroform-like odor.It is not easily soluble in water, but miscible with most organic solvents.
Chloroacetic acid was first prepared (in impure form) by the French chemist Félix LeBlanc (1813–1886) in 1843 by chlorinating acetic acid in the presence of sunlight, [3] and in 1857 (in pure form) by the German chemist Reinhold Hoffmann (1831–1919) by refluxing glacial acetic acid in the presence of chlorine and sunlight, [4] and then by the French chemist Charles Adolphe Wurtz by ...
Nearly 20 million tons of 1,2-dichloroethane are produced annually in the United States, Western Europe, and Japan. [7] Production is primarily achieved through the iron(III) chloride-catalysed reaction of ethylene and chlorine: H 2 C=CH 2 (g) + Cl 2 (g) → ClC 2 H 4 Cl (l) (ΔH ⊖ r = −218 kJ/mol)
