msds information

trimethyl phosphite usage and synthesis

general description	a clear colorless liquid with a strong foul odor. flash point 99°f. denser than water and insoluble in water. vapors heavier than air. used to make other chemicals.
air & water reactions	highly flammable. insoluble in water and denser than water. slowly reacts with water to form phosphoric acid and corresponding organic alcohol.
reactivity profile	as soon as trimethyl phosphite contacted a small amount of magnesium perchlorate in a flask, there was a flash and an explosion that shattered the flask (allison 1968).
health hazard	symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.
fire hazard	special hazards of combustion products: toxic fumes of po x
