Description
Colorless to yellow to dark-red, oily liquid; [NIOSH] Ignites in air; Insoluble in water; [Sullivan, p. 979]
Sources/Uses
Used as an anti-knock agent in gasoline in Europe; may be generated when fine iron particles react with carbon monoxide; [ACGIH]
Comments
Acute inhalation studies of animals: lung irritation and pulmonary edema are prominent toxic effects. [ACGIH] Also can cause liver, kidney, and CNS injury; [CAMEO] Readily absorbed through the skin; Acute exposure can injure the lungs (pneumonitis), liver, and kidneys. Chronic exposure can cause iron overload and hemochromatosis. [Sullivan, p. 982] See "ORGANOMETALS."
