CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Trifluoroacetyl chloride appears as a colorless gas. Shipped as a liquid under own vapor pressure. Contact with the unconfined liquid may frostbite unprotected skin. Very toxic by inhalation and may severely irritate skin, eyes, and mucous membranes. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. |
|---|---|
| Color/Form | Colorless gas |
| Odor | Pungent odor |
| Boiling Point | -27 °C |
| Solubility | Exothermic reaction with water to form water soluble trifluoroacetic acid and byproduct HCl. |
| Density | 1.384 g/mL at 20 °C |
| Vapor Pressure | 72 psia at 25 °C (3273 mm Hg) |
| Stability/Shelf Life | Stable under recommended storage conditions. |
| Decomposition | When heated to decomposition it emits very toxic fumes of F- and Cl-. |
| Corrosivity | Corrosive to materials |
| Heat of Vaporization | 20 kJ/mol |
| Other Experimental Properties | Reacts avidly with water and with moisture in the air to give fumes of hydrogen chloride, a water-soluble toxic gas. |
| Chemical Classes | Toxic Gases & Vapors -> Acid Halides |
