phosgene
- n a colorless poisonous gas that smells like new-mown hay; used in chemical warfare
- For example, phosgene, which was first used as a military weapon in World War I, was first made by British Chemist John Davy in 1812.
- Using bombs, artillery shells, mortars, multiple-rocket launchers, air-delivered sprays or even land mines, the Soviets can attack with phosgene, mustard gas, hydrogen cyanide .
- Eventually the consensus of opinion was that the phosgene should be disintegrated by the admixture of other chemicals into a harmless residual product.
