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]
The most important is dichloromethane, which is mainly used as a solvent. Chloromethane is a precursor to chlorosilanes and silicones . Historically significant (as an anaesthetic), but smaller in scale is chloroform, mainly a precursor to chlorodifluoromethane (CHClF 2 ) and tetrafluoroethene which is used in the manufacture of Teflon.
The handling of this chemical may incur notable safety precautions. ... log 10 of Dichloromethane vapor pressure. Uses formula: ...
The International Bottled Water Association has adopted a tougher standard for its members: 5 parts per trillion for one PFAS compound and 10 parts per trillion for more than one compound.
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.
The potential hazards of a chemical or a substitute candidate must be assessed by noting the toxicity of the chemical to both humans and the environment. An assessment of the chemical should list the dangerous properties of the chemical, such as flammability or corrosivity. [3]
1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2.The two compounds are isomers, each being colorless liquids with a sweet odor.
Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
