PROCESS FOR THE SYNTHESIS OF DIETHYL ETHYLPHOSPHONATE

摘要

Diethyl ethylphosphonate is formed by the catalytic rearrangement of triethyl phosphite in a reaction medium at elevated temperature, preferably using an ethyl iodide as the rearrangement catalyst, employing a heel of diethyl ethylphosphonate in the reaction medium when the reaction has begun with maintaining of the reaction medium at a temperature above the boiling point of the triethyl phosphite (for example, a temperature of from about 175 DEG C to about 185 DEG C) and addition of the triethyl phosphite to the reaction medium at a rate slow enough to maintain that temperature.
