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 .
Another source of poisoning is exposure to the organic solvent dichloromethane, also known as methylene chloride, found in some paint strippers, [89] as the metabolism of dichloromethane produces carbon monoxide. [90] [91] [52] In November 2019, an EPA ban on dichloromethane in paint strippers for consumer use took effect in the United States. [92]
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 most common exposure route to chemicals in the work environment is through inhalation. [4] Gas, vapour, mist, dust, fumes, and smoke can all be inhaled. Those with occupations involving physical work may inhale higher levels of chemicals if working in an area with contaminated air.
There is a fundamental difference between using heat and UV light to make dichloromethane. UV light is much easier to use and is less dangerous than heat. SchicagoS 18:20, 10 April 2012 (UTC) If you want to claim that this is an easier way to make dichloromethane, you will need to find a reliable source that reports this.
