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 chromyl chloride test involves heating a sample suspected to contain chlorides with potassium dichromate and concentrated sulfuric acid.If a chloride is present, chromyl chloride forms, its presence being indicated by the formation of red smoke.
This process is known as volatization or air stripping. Water is deposited into the system through the top and air is ventilated in through the bottom. Water that reaches the bottom of the system is typically considered treated, but additional testing may be done to determine if it is safe for consumption. [1]
Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning. There the gas is liquefied in the condenser , where the heat of vaporization is released, and evaporated in the evaporator , where the heat of ...
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.
Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.
