CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Diethylzinc is a pyrophoric liquid with a garlic-like odor. It is stable when it is shipped in sealed tubes with carbon dioxide. It may decompose violently in water and ignite spontaneously with air. It is toxic by ingestion. If exposed to heat or flame, containers of this material may explode. It is used as an aircraft fuel.
