Lung Injurants Choking Agents

Chlorine, CI2, is a corrosive industrial gas (bp -34 °C) with a pungent and eharaeteristic odour, and yellow-green eolour. It is produced industrially by the eleetrolysis of brine and used extensively in the production of industrial 

Perfluoroisobutene, (CF3)2C=CF2 (bp 7 °C), included in Schedule 2 of the CWC, is also a lung injurant that causes pulmonary oedema. It is a by-product of Teflon production. Like phosgene it is a reactive electrophile. It is not known to have been weaponised but was studied as a potential hydrophobic canister penetrant.

Choking agents injure an unprotected person chiefly in the respiratory tract (the nose, the throat, and particularly the lungs). In extreme cases membranes swell, lungs become filled with liquid, and death results from lack of oxygen thus, these agents "choke" an unprotected person. Fatalities of this type are called "dryland drownings."...
