ECHEMI Editorial ReferenceDiethyl phosphite is an organophosphorus compound, a colorless liquid with a tetrahedral structure. Its molecular formula is C4H11O3P, its molecular weight is 138.1 g/mol, its boiling point is 187-188°C, its relative density is 1.072 g/cm3, its refractive index is 1.4080, and its flash point is 90°C. Diethyl phosphite is soluble in organic solvents such as ethanol and ether, but is incompatible with strong oxidants, strong acids, acyl chlorides, and strong bases. It may decompose when exposed to moisture and is flammable. Diethyl phosphite is a commonly used reagent that can use the high reactivity of the PH bond to generate other organophosphorus compounds.Basic Info-
