trifluoromethane

A scientist carefully releases trifluoromethane from a small canister into a sealed glass apparatus.

Definition

Noun 1. A colorless, nonflammable gas: Trifluoromethane is a chemical compound consisting of methane in which three hydrogen atoms have been replaced by fluorine atoms. Its chemical formula is CHF₃. 2. A type of haloform: It is classified as a haloform, similar in structure to chloroform (CHCl₃), but with fluorine atoms instead of chlorine.

Usage Examples
  • The refrigerant system was charged with trifluoromethane.
  • Trifluoromethane (CHF₃) is also known by the designation HFC-23.
  • As a haloform, trifluoromethane shares a general structural similarity with bromoform and iodoform.
Advanced Usage
  • In industrial contexts: Trifluoromethane is primarily used as a refrigerant (R-23) and as a gaseous fire suppression agent. It is also a byproduct in the manufacture of other fluorinated compounds.
  • In environmental science: It is classified as a potent greenhouse gas with a high global warming potential, leading to discussions about its emission controls and alternatives.
Variants and Related Words
  • HFC-23: A standard industrial designation for trifluoromethane, indicating it is a Hydrofluorocarbon.
  • Fluoroform: A synonym for trifluoromethane.
  • Haloform: The class of compounds with the formula CHX₃, where X is a halogen (e.g., chloroform CHCl₃, bromoform CHBr₃).
Synonyms
  • Fluoroform
  • HFC-23
  • Carbon trifluoride hydride
  • Refrigerant 23 (R-23)
Notes on Meaning

While its basic definition is a specific chemical compound, the term's practical usage is almost exclusively found in technical, industrial, and environmental contexts rather than in everyday language. Its identity as a haloform links it to a well-known family of organic compounds.
