| Hazard Information | Back Directory | [Chemical Properties]
dark brownish to dark grey powder | [Uses]
In the fluorination of hydrocarbons. | [Purification Methods]
It is highly TOXIC because it liberates HF and F2. It is very hygroscopic and reacts violently with H2O. It is a powerful oxidising agent and liberates O3 from dilute acids, and I2 from I-solution. Store it in quartz or iron ampoules. It is white when pure; otherwise it is brown-tinged. It is thermally stable up to 700o. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 241 1963.] |
