CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Hexafluoroacetone is a colorless, toxic, and highly reactive gas. At ambient temperatures, it is likely to generate a considerable amount of vapor. It is an irritant to skin, eyes and mucous membranes and is toxic by ingestion, skin absorption, and inhalation. When heated to high temperatures it emits toxic fluoride fumes. Prolonged exposure of the container to fire or intense heat may cause it to violently rupture and rocket. It is used in the production of other chemicals. |
