METHYLPHOSPHONOTHIOIC DICHLORIDE Chemical Properties,Usage,Production

General Description

A colorless liquid with a pungent odor. Noncombustible. Toxic by inhalation. Denser than water. Corrosive to metal and tissue.

Air & Water Reactions

Reacts with water to form hydrochloric acid, reaction may be violent.

Reactivity Profile

METHYL PHOSPHONOTHIOIC DICHLORIDE is water reactive. Incompatible with strong oxidizing agents, alcohols, bases( including amines). 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

Inhalation causes irritation of nose and throat; effects are quite similar to those of phosgene. Ingestion causes irritation of mouth and stomach. Delayed, painful eye irritation may occur from exposure to vapor; liquid causes severe irritation. Contact with skin causes irritation and burns.

Fire Hazard

Special Hazards of Combustion Products: Irritating hydrogen chloride, sulfur dioxide and other fumes may be formed in fire.

Safety Profile

A corrosive irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits very toxic fumes of Cl-, POx, and SOx.
