Überblick
Methyl fluoride (or fluoromethane) is a colorless flammable gas which is heavier than air. It has an agreeable ether-like odor. It is narcotic in high concentrations. It burns with evolution of hydrogen fluoride. The flame is colorless, similar to alcohol. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

Reactive GroupFluorinated Organic Compounds
Reactivity AlertsHighly Flammable
Reactivity Profile
Halogenated aliphatic compounds, such as METHYL FLUORIDE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. The prolonged mixing of halogenated solvents with metallic or other azides may cause the slow formation of explosive azides, for example methylene chloride and sodium azide, [Chem. Eng. News, 1986, 64(51)].
