Trifluoromethane Usage And Synthesis
Trifluoromethane, also known as Halocarbon-23, is a colorless, nonflammable, and nontoxic gas with a slight ethereal odor at ambient conditions.
Refrigerant for low temperetures.
Trifluoromethane is a colorless nonflammable gas. Trifluoromethane is shipped as a liquid under pressure. Trifluoromethane may be narcotic in high concentrations. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Trifluoromethane is used as a refrigerant.
TRIFLUOROMETHANE, R-23, is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.
Trifluoromethane is considered an asphyxiant.Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
At very high concentrations, trifluoromethane may produce cardiac arrhythmias or arrest due to sensitization of the heart to adrenaline and noradrenalin. Exposure to fluorocarbon thermal decomposition products may produce flu-like symptoms including chills, fever, weakness, muscular aches, headache, chest discomfort, sore throat, and dry cough. Complete recovery usually occurs within 24 hours after exposure.
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
Narcotic in high concentration. A mild respiratory irritant. Mutation data reported. See also FLUORIDES. When heated to decomposition it emits toxic fumes of F-.
