Definition

ChEBI: Phosphorus trifluoride is a phosphorus halide.

Safety Profile

Moderately toxic by inhalation. A severe eye, skin, and mucous membrane irritant. Explodes on contact with dioxygen difluoride. Violent reaction or ignition with borane, diborane, F2. hexafluoroisopropylideneamino lithum, O2. Will react with water or steam to produce toxic and corrosive fumes. Dangerous; when heated to decomposition it emits highly toxic fumes of Fand POx. See also HYDROFLUORIC ACID, FLUORIDES, and PHOSPHORUS PENTAFLUORIDE
