msds information

triethyl phosphite usage and synthesis

chemical properties	clear colorless liquid
general description	a clear colorless liquid with a strong foul odor. flash point 130°f. less dense than water and insoluble in water. vapors heavier than air.
air & water reactions	flammable. insoluble in water.
reactivity profile	triethyl phosphite is colorless, moderately toxic liquid, combustible. flammable when exposed to heat or flame. when heated to decomposition triethyl phosphite emits toxic fumes of oxides of phosphorus [lewis, 3rd ed., 1993, p. 1271].
health hazard	exposure to high concentrations may cause headache, nausea, and dizziness due to reduced chlolinesterase activity.
fire hazard	special hazards of combustion products: may form hazardous decomposition products.
