How is hydrogen cyanide used in chemical warfare?

How is hydrogen cyanide used in chemical warfare?

Hydrogen cyanide (AC) is a chemical warfare agent (military designation, AC). It is used commercially for fumigation, electroplating, mining, chemical synthesis, and the production of synthetic fibers, plastics, dyes, and pesticides.

What molecule is poisoned by hydrogen cyanide?

Hydroxocobalamin (vitamin B12a) appears to be useful as an antidote and is generally first-line. Sodium thiosulphate may also be given. Historically cyanide has been used for mass suicide and by the Nazis for genocide….Cyanide poisoning.

Is hydrogen cyanide gas explosive?

Vapors may travel to a source of ignition and flash back. Hydrogen Cyanide may form an ignitable vapor/air mixture in closed tanks or containers. Anhydrous and Unstabilized Hydrogen Cyanide are severe explosion hazards and can polymerize violently, resulting in fires and explosions.

What does hydrogen cyanide do to your lungs?

Breathing small amounts of hydrogen cyanide may cause headache, dizziness, weakness, nausea, and vomiting. Larger amounts may cause gasping, irregular heartbeats, seizures, fainting, and even rapid death. Generally, the more serious the exposure, the more severe the symptoms.

What is the difference between cyanide and hydrogen cyanide?

There are several chemical forms of cyanide. Hydrogen cyanide is a pale blue or colorless liquid at room temperature and is a colorless gas at higher temperatures. It has a bitter almond odor. Sodium cyanide and potassium cyanide are white powders which may have a bitter almond-like odor.

What is cyanide used for in war?

Hydrogen cyanide, under the name Zyklon B, was used as a genocidal agent by the Germans in World War II. Reports have indicated that during the Iran-Iraq War in the 1980s, hydrogen cyanide gas may have been used along with other chemical agents against the inhabitants of the Kurdish city of Halabja in northern Iraq.

What causes hydrogen cyanide gas?

Hydrogen cyanide (CN), the gaseous form of cyanide, is generated by the combustion of nitrogen- and carbon-containing substances such as wool, silk, cotton, and paper as well as synthetic substances such as plastic and other polymers.

What emits hydrogen cyanide?

HCN is produced commercially by the reaction of ammonia, methane, and air over a platinum catalyst or from the reaction of ammonia and methane. HCN is also obtained as a by-product in the manufacture of acrylonitrile and may be generated during many other manufacturing processes (Pesce 1994).

How do you handle hydrogen cyanide?

Wear chemical splash goggles and impermeable gloves, such as Teflon, Siver Shield, 4H, or butyl rubber. Do not use PVC or polyethylene. Liquid hydrogen cyanide is highly flammable. Keep away from ignition sources.

How is cyanide gas produced?

The principal process used to manufacture cyanides is the Andrussow process in which gaseous hydrogen cyanide is produced from methane and ammonia in the presence of oxygen and a platinum catalyst.
