How many people did phosgene kill in ww1?

World War I ends with 1.3 million casualties caused by chemical weapons, including 90,000 to 100,000 fatalities, primarily from phosgene.

What gas killed the most soldiers in ww1?

It is estimated that as many as 85% of the 91,000 gas deaths in WWI were a result of phosgene or the related agent, diphosgene (trichloromethane chloroformate).

How did phosgene kill?

Phosgene is an irritant that’s six times more deadly than chlorine. Instead of announcing its presence in a yellow-green cloud, phosgene is colorless and takes its time to kill. Victims don’t know they’ve been exposed until days after inhaling it, at which point their lungs fill with fluid and they suffocate.

How many soldiers died from mustard gas in ww1?

90 000 deaths
By the time of the armistice on November 11, 1918, the use of chemical weapons such as chlorine, phosgene, and mustard gas had resulted in more than 1.3 million casualties and approximately 90 000 deaths (Table 1 ▶).

What does phosgene gas do to a person?

Difficulty breathing or shortness of breath. Nausea and vomiting. Skin contact can result in lesions similar to those from frostbite or burns. Following exposure to high concentrations of phosgene, a person may develop fluid in the lungs (pulmonary edema) within 2 to 6 hours.

Can you survive mustard gas?

Exposure to mustard gas is usually not lethal and most victims recover from their symptoms within several weeks. Some, however, remain permanently disfigured as a result of chemical burns or are rendered permanently blind. Others develop chronic respiratory diseases or infections, which can be fatal.

How do you make phosgene?

Production. Industrially, phosgene is produced by passing purified carbon monoxide and chlorine gas through a bed of porous activated carbon, which serves as a catalyst: CO + Cl2 → COCl2 (ΔHrxn = −107.6 kJ/mol) This reaction is exothermic and is typically performed between 50 and 150 °C.

What is the common name of phosgene?

carbonyl chloride
phosgene, also called carbonyl chloride, a colourless, chemically reactive, highly toxic gas having an odour like that of musty hay, used in making organic chemicals, dyestuffs, polycarbonate resins, and isocyanates for making polyurethane resins.
