Triethyl phosphite Chemical Properties,Uses,Production

Chemical Properties

Colorless liquid. Insoluble in water; soluble in alcohol and ether. Combustible.

Uses

Synthesis, plasticizers, stabilizers, lubricant and grease additives.

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.

Safety Profile

Moderately toxic by ingestion. A skin and eye irritant. Flammable liquid when exposed to heat, sparks, or flame. When heated to decomposition it emits toxic fumes of POx.
