Arsenic trifluoride is a colorless oily liquid; fumes in air; etches glass; density 2.666 g/ml at 0°C; boils at 60.4°C; vapor pressure 100 torr at 13.2°C; solidifies at -8.5°C; decomposes in water; soluble in alcohol, ether, benzene and ammonia solution.
Fluorinating reagent, catalyst, ion implantation
source, and dopant.
Arsenic trifluoride is prepared by reaction of arsenic trioxide with fluorosulfonic acid. Also it may be prepared by treating arsenic trioxide with a mixture of sulfuric acid and calcium fluoride.

carcinogen. A poison by inhalation. Strong
reaction with P203. When heated to
decomposition it emits very toxic fumes of
As and F-. See also FLUORIDES and
