General Description

A colorless liquid with a pungent odor. Denser than water. Very toxic by inhalation.

Air & Water Reactions

Highly flammable. Pyrophoric, will spontaneously ignite on contact with water or moisture in air. In water the compound also decomposes to form hydrochloric acid, [AAR 1991].

Reactivity Profile

ETHYL PHOSPHONOUS DICHLORIDE is an acid halide and organophosphate. Flammable/combustible material. May ignite on contact with air or moist air. May burn rapidly with flare-burning effect. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Health Hazard

Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Fire Hazard

Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.

Safety Profile

Moderately toxic by inhalation. Corrosive. A severe irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits very toxic fumes of POx, Cl-, and phosphine. See also PHOSPHINE.
