Related to Fluoroform: trifluoromethane


(organic chemistry)
CHF3 A colorless, nonflammable gas, boiling point 84°C at 1 atmosphere (101,325 pascals), freezing point 160°C at 1 atmosphere; used in refrigeration and as an intermediate in organic synthesis. Also known as propellant 23; refrigerant 23; trifluoromethane.



(trifluoromethane), CHF3, a colorless gas, with a boiling point of –82.5°C. Unlike chloroform, fluoroform is an inert compound; for example, it is resistant to the action of alkalies. It is prepared from chloroform by an exchange reaction with SbF3 or HF or from chlorotrifluoromethane (Freon-13) and H2, as well as by other methods. It is used as a refrigerant.

According to PBE/6-311++G(d,p) calculations, structural evidence has been adduced to show that the blue-shifting hydrogen bonds and red-shifting hydrogen bonds result from the shortening and lengthening of the C-H of fluoroform and chloroform, respectively.
Finally, from the foaming agent series, the more polar fluoroform with a higher density and higher dielectric constant than carbon dioxide, solubilizes the reactants at a lower pressure.
