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. [12]
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.
a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides. In the laboratory, the related reaction involving zinc chloride in concentrated ...
A Snyder column can be used with a Kuderna-Danish concentrator to efficiently separate a low boiling extraction solvent such as methylene chloride from volatile but higher boiling extract components (e.g., after the extraction of organic contaminants in soil). [25]
In addition, calcium chloride is widely used as a de-icer, since it is effective in lowering the melting point when applied to ice. [23] Examples of covalently-bonded chlorides are phosphorus trichloride, phosphorus pentachloride, and thionyl chloride, all three of which are reactive chlorinating reagents that have been used in a laboratory.

In 1966, this was increased to 450 pounds (204 kg) per second. Air is also cooled by a two-stage heat exchanger. The first stage uses 110,000 US gallons (416 m 3) of 20% calcium chloride brine pre-cooled to 24 °F (−4 °C). The second stage uses 137,500 US gallons (520 m 3) of methylene chloride pre-cooled to −97 °F (−72 °C). This can ...
