The Uses of DIETHYL ETHYLPHOSPHONATE

Diethyl Ethylphosphonate can be used as a flame retardant, and also used as a general reagent in phosphinoalkene and phosphinoalkyne synthesis.

The Uses of DIETHYL ETHYLPHOSPHONATE

Diethyl ethylphosphonate is used for heavy-metal extraction and solvent separation. It is also used as a gasoline additive, antifoam agent, plasticizer and textile conditioner. Further, it serves as an antistatic agent, flame retardant and as a general reagent in phosphinoalkene and phosphinoalkyne synthesis.

General Description

Colorless liquid with a mild odor.

Air & Water Reactions

Slightly water soluble. May hydrolyze under acid or basic conditions .

Reactivity Profile

Organophosphates, such as DIETHYL ETHYLPHOSPHONATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
