| Diphosgene Usage And Synthesis |
| Chemical Properties |
clear colorless liquid |
| Uses |
In organic synthesis; as war gas. |
| General Description |
Colorless liquid, odorless to fruity. |
| 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. |
| Hazard |
Toxic by inhalation and ingestion, strong irritant to tissue. |
| 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. |
| Safety Profile |
Low toxicity by inhalation. A corrosive liquid. When heated to decomposition it emits toxic vapors of Cl-.
