tetrachloromethane
Noun: A colorless, nonflammable liquid compound with the chemical formula CCl₄. It was historically used as a solvent for fats and oils, a cleaning agent, and in fire extinguishers, but its use has significantly declined due to its high toxicity.
Tetrachloromethane is a technical and scientific term. It is primarily used in chemistry, industrial, and environmental safety contexts to refer to this specific chemical compound.
Scientific Context:
- The laboratory procedure required the use of tetrachloromethane to dissolve the lipid sample.
- Due to its ozone-depleting properties, the production of tetrachloromethane is now strictly regulated.
Historical/Industrial Context:
- Old fire extinguishers sometimes contained tetrachloromethane.
- Before its toxicity was fully understood, tetrachloromethane was a common industrial solvent.
- Environmental Science: The term is used when discussing persistent organic pollutants or ozone layer depletion, as tetrachloromethane is a potent ozone-depleting substance.
- The treaty mandates the phase-out of tetrachloromethane and other halocarbons.
- Carbon tetrachloride: This is the most common synonym and alternative name for tetrachloromethane.
- Perchloromethane: Another systematic chemical name for the same compound.
- Halocarbon (n): A class of chemical compounds that includes tetrachloromethane.
- Chlorinated solvent (n): A category of industrial solvents to which tetrachloromethane belongs.
- Carbon tetrachloride: The most widely used synonym.
- Carbon tet (informal abbreviation).
While tetrachloromethane strictly refers to the pure chemical compound (CCl₄), its historical applications define its common associations: 1. As a Solvent: For dissolving greases and oils. 2. As a Refrigerant and Propellant: In early applications. 3. As a Fire Suppressant: In specialized fire extinguishers (now obsolete). 4. As a Chemical Intermediate: In the production of other chemicals.
Its primary meaning today is that of a toxic and environmentally hazardous chemical whose use is heavily restricted.
-
a colorless nonflammable liquid used as a solvent for fats and oils; because of its toxicity its use as a cleaning fluid or fire extinguisher has declined
