503-38-8 Usage

Hazard

Toxic by inhalation and ingestion, strong irritant to tissue.

Definition

diphosgene: A colourless liquid,ClCO.O.CCl3, originally used in 1916by Germany in World War I as achemical warfare agent. It is nowused as a reagent in organic synthesis.See also carbonyl chloride.

Chemical Properties

clear colorless liquid

General Description

Colorless liquid, odorless to fruity.

Safety Profile

Low toxicity by inhalation. A corrosive liquid. When heated to decomposition it emits toxic vapors of Cl-.

Air & Water Reactions

Decomposes slowly in water or moist air (or when inhaled) to form very corrosive hydrogen chloride gas (hydrochloric acid) and carbon monoxide.

Fire Hazard

Some may burn but none ignite readily. Vapors from liquefied gas are initially heavier than air and spread along ground. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.

Uses

In organic synthesis; as war gas.
