Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane.
1. Most of the total production of chloroform is used to produce monochlorodifluoromethane (CFC22) which is used as a refrigerant but also as an intermediate in the manufacture of tetrafluoroethene which then may be polymerised (PTFE).
2. Chloroform is also used in the production of dyes, pharmaceuticals and pesticides. Its use as a solvent and application in anaesthesia is rapidly on the decline.
