| | ARSENIC TRIFLUORIDE Usage And Synthesis |
| Description | Arsenic trifluoride is a chemical compound of arsenic and fluorine with the chemical formula AsF3. It is a colorless liquid which reacts readily with water. | | Chemical Properties | Mobile liquid that fumes in air. | | Physical properties | 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. | | Uses | Fluorinating reagent, catalyst, ion implantation
source, and dopant.
| | Preparation | 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. | | Hazard | Extremely toxic. | | Safety Profile | Confirmed human
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
ARSENIC COMPOUNDS. |
