Boiling Point:111.5 °C
Flash Point:82°F
Refractive Index:n20/D 1.408(lit.)
Water Solubility:Reacts
Storage Conditions:Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Never allow product to get in contact with water during storage. Storage class (TRGS 510): Flammable liquids.
Vapor Pressure:Vapour pressure, kPa at 25°C: 3.2
Vapor Density:Relative vapour density (air = 1): 4.3
Flammability characteristics:Class IC Flammable Liquid: Fl.P. at or above 73°F and below 100°F.
Odor:Irritating, pungent, oily, pyridine-like odor
Experimental Properties:Air sensitive|Pour point: less than -60 °C|Hydrolyzed by hot water|Decomposes to dimethyl phosphite and methanol in water|Hydroxyl radical reaction rate constant = 7.10X10-10 cu cm/molec-sec at 25 °C
Air and Water Reactions:Highly flammable. Insoluble in water and denser than water. Slowly reacts with water to form phosphoric acid and corresponding organic alcohol.
Reactive Group:Sulfonates, Phosphonates, and Thiophosphonates, Organic
Reactivity Alerts:Highly Flammable
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).
